I would say unless you have a kit already defined tubecad is more advanced especially hybrid. Often you will need more components/alter schematics to cover all the scenerios and variations in physical components.
Matching and selecting components in your hands plays a lot in terms of building good sounding amps. Tubes are forgiving but hybrid is far less forgiving - especially direct dc coupled designs. (I have a hybrid circlotron design based closely on a tubecad idea i’m working on).
Last point is - ltspice is good to test ideas but it is an ideal and the models aren’t fool proof for all conditions. (Thermal etc) but it will teach you alot as you go through the process.
Looking at those long posts I lost interest .So you want 300B "tubey" sound with 10 inch bass drivers...
Then mambo jambo voiced class d amps...then you or others imagine you'll get the 300B voicing through simulations without output transformers...and you didn't settled on 2.0, 2.1 or 5.1 system...
Starting with PS audio BS spread all over the internet we all found out that PA speakers aren't made for audiophiles...PA speakers are f...made for open spaces and they can sound better than any audiophile system because they don't need to suffer of 6 walls reflections , but they are made specifically for open spaces and to be operated by proffesionals to render a live concert that others try to record and sell you as high rez audio file that you strive to reproduce with your damn 10 inch woofers plus sattelites audiophile speakers and "tubey" class d + 6dj8 amplification inside 6 walls!
You need to understand what you want.A transformer +tube is acting like a compressor and harmonic noise gate for the higher than 3 order harmonics, or more like tape compression where H3/H2 gets substituted by H2/H3 ratio.Read Eric K Pritchard for that.
You'll struggle like hell to find a good FX formula to replace some of a 2.0 300B output transformer + high sensitivity speakers on 10 inch multiway speakers and eventually you'll spend way more money and time on irrelevant observations than if you'd buy 300b+ Tango ot +r-core supply tansformers + Voight speakers as new.
My advice for now:
If you think you cannot afford a true 300B system
buy some Alesis compressors or just free compressor-limmiter plugins for your computer plus any amps and speakers you can afford and learn how to use them!

I hope you can at least get a laugh out of what I am trying to do. It really is not worth loosing your composure like that over this. There is some merit using some elegance in speech!
I think building one thing todo everything will prove unviable. What dreamth is suggesting is a D class 5.1 then use a software filters/DSP to ajust the sound on they fly to feed out - an option is a pure digital DSD512 power amp instead of class d with analogue input.
A 300b as a line buffer is going to take the preamp/driver tube characteristics so perhaps a simple 6sn7 line buffer would offer a close tubey sound for an analogue in class D.
Note tubes will introduce noise compared to a SS pre section or an DSD512.
I don't know what territory this is going!
Isn't the tiny amp for flavouring that I proposed already a 6sn7 based? I have already got rid of most of the menu diving stuff from my setup. His is not a suggestion, I do not have a deficiency with the language to not understand that. The earlier unedited masterpiece is the most amazing piece of online forum smackdown that I have encountered in years!!!
Class d - in the project
DSP - in the project
6sn7 - in the project
I do not understand any of the contention, or why do my fooling around with these have to attract the word F*-+/? in response? Doe what I am messing with upset sensibilities so much?
I don't get a laugh at anything these days...
And I live in a 3rd world country where there are less than 5 people in 19 million general population owning a 300B +tango ot...I just tried to get you on track with 3rd world country type of resources and language...Alesis compressor-limitters sell for 50...100 bucks second hand and they do incredible things to the sound.And people mod them too for better dynamics.Then vst plugins is the new audio in the professional audio world for at least 15 years now , that world that makes the music for us.Just talk to a mastering audio engineer if you can't believe me.Some vst plugins costs thousands of dollars...and they are just coded pieces of software doing limited fx's .You get tape or tube flavour for 30 bucks if you can't find free vst..what's the point in spending considerable time and resources to get approximations of a true 300b system? You don't even know how such a system sounds in your home.

Hey man, using your country to explain your manner of speech or your angle is poor form. I was born in Fiji, most of my life I have been quite poor as I won’t do anything that weighs on my conscience. I stopped a very lucrative tackle biz as I couldn't live with the idea of selling things to put holes in creatures for fun. I eat fish and catch fish, but not for sport. I live in a regional area where I face bush turkeys daily, but I do not feel the need to speak thus
A man's speech shows his class. I worked as a taxi driver in Sydney city for 7 years. I encountered folks from every background. I can judge that a man will speak how he wants to, where he is from has no bearing on it
In 1992, I had a 300b system in another home, similar to this place. It's my favourite sound, and no emulation comes close to the glint on the over driven bass notes. I have full FL Studio, Ableton and such. I would rather have a bass, mid, treble and overdrive knobs. I do not expect you to understand this sentiment
Save up for your 300b man, or make something and sell it to build funds. I could have bought a 300b amp, what's the challenge in that, I don't want that larger unit in my entertainment area. The 300b is cheaper than a JL sub amp in my car. I saved and gigged for that. I would take a guess that something along my lines was a pipe dream of yours at some point, and you were unable to pull it off, would explain some of the swearing and such
Going back to your attempt to paint your manner as a product of your country, do you know what a panga is?
It's a smallish boat that is popular in Third World countries as they can be built to United Nations published plans from very basic materials like planks and ply (ply on frame rather than a true monocoque)
Does that mean that the person from that country should not aspire to and run a long term project to end up with something that looks like a lambo on water using existing materials and bringing alternates into play?
Folks like you on a boat forum were telling me to not be stupid and build a panga. What I really wanted to and did build was this. I studied naval architecture applicable to my project, did the sims and engineering and took a year to build this on the remote side of the main Fiji island with a miniscule budget. Born in Fiji, I still speak respectfully
Boat build - the build log if you are interested in what someone from a 3rd world country can do if they want to
Good for you and the like! Have I said anything about me being in need for a b300 setup? I trust you finding the solution by yourself! Have a good weekend fishing only for survival then cause obviously you don't do it for fun! I can't even apply for a work visa to Australia without paying 5000 dollars so we will never meet in this life!You don't need such stupid guys like me around anyway... Good luck!
Tube preamp has bass guitar input and aux input. And preamp output. With tone control. just use preamp.

I was going past an op shop window this morning and spotted this! Looks like a fully integrated surround sound home entertainment system in fairly intricate cabinetry of that time made by a major Japanese manufacturer under their audiophile focused brand
It has a live input for mic or guitar and does a lot without menu diving!!!!!
I am a bit surprised that no one here really seems to get that I would like to make a modern version of this with some tube flavours too. But instead this concept is pretty much being called stupid by many and even attracted swearing and bad language. I cannot understand why a system like this is so upsetting for so many
Seems like a fair time for yours truly to gracefully lose some composure, too. Not at the members, but the forum, one professional to another. As a former system admin and host for industry forums and websites here in Australia, I have run forums where national scale clubs that are properly registered and inc operated are able to hold annual general meeting and such online
This forum creates divide, segregation, intolerance, elitism and poor communications. You have a category for tubes and a category for instruments and amps, and all this does is the same old boring 'this needs to be moved to the other section'. Audiophile gear folks get programmed to look down on live gear, even though logic says their equipment would just be pretty furniture if their program material wasn't created on live gear in the first place
If I can have the intelligence to know that the hi-fi gear goes on to reproduce the stuff played on lower-fi gear after mastering, then surely others have the intelligence to know that the lower-fi gear is not a good choice to use alongside hi-fi and that a different approach is needed to produce a cohesive mix. Whose intelligence says that a bass DI with a 50hz low pass will make a bass in a living room playing with a CD, sound as full and pretty as the kick and keyboards on the recording? A bass plugged into one of these old school hi-fi sounds sweeter and more cohesive than dragging in a Bassman alongside a Class DP amp using MLTLPLLLCOOLJ speakers
Rant over, back in composure and looking for a place to log my project

Hey man, thanks for pointing this one out. Taking a good look at this too, maybe I can use some things from the schematic
The issue is that it becomes complicated fast.View attachment 1087029View attachment 1087026

Different tube designs work best for audio, for mic and for instruments. That in turn leads to complex power supplies. The instrument amp needs a whole design (from input to output trans to speaker) unless you decide to go for a modelling design.
A hifi tube pre into a SS power will given you good audio. Add tubes for instrument distortion/gain will help but you will find the true tube amp sound needs something different to hifi.
You could use an existing SS 5.1 amp and then add a tube pre. Attempting to make a 5.1 from scratch is difficult (dsp).
It would be faster/cheaper to take a used 5.1 then add to it which us what i think dreamth is suggesting.

Learning about this. I can use the information presented for the top schematics tutorial to follow the circuit in the lower schematic untill I hit the 100k resistor to ground after the coupling cap. What does this 100k resistor do in this schematic?
Ground Leak Resistor
Is this the answer to my question? I am only starting out in this so would appreciate if someone confirmed this

The 100K is part of the tone stack. As all the paths after that end in a capacitor DC will not flow. AC current will but that is then shaped by the tone stack, through the volume pot and into the grid of the next tube. The tone stack provides a tuneable set of filters that all AC to pass to the next stage or to ground (actually the return to the power filter cap).
The grid leak resistors are the 1M ohm.
