I finally finished the amplifier. No hum, and it sounds clear and the bass is deep and good.. Playing Sting with the album "If on a winters Night". Great album with lovely sound, good production. This amplifier turned blue, tried to find the same blue color as Edcor's output transformers, and hit...like almost-ish? Has red amplifiers, black, green, and then this one just had to be blue. Wondering what color the next amplifier will get? thank you all for a great forum, with lots of good people!

Glad the amp turned out well. I've always liked the Lacewood V2.
By the way... "Edcor Blue" is actually Gentian Blue #00099. The RAL number is 5010.
Sometimes you can find paint vendors who can produce RAL compliant colors. Or you can get a physical RAL fan deck and have someone match the color of your choice to their pigment systems.
Here are the component mixes in various digital systems:
RGB: 0, 79, 124 CSS: rgb(0, 79, 124);
HSL: 202, 100, 24 CSS: hsl(202, 100%, 24%);
HSB: 202, 100, 49 Hex: #004f7c
CMYK: 100, 70, 5, 15 Websafe: #006666

No, it doesn't come from a toy car. This is a volume control from an old radio I found in a rubbish dump thirty/forty years ago. Probably the volume wheel is eighty to ninety years old?. A bit tough with a bit of vintage?
You live in a country where you can buy any parts, so take it seriously.

Ok, that's possible, but don't quite understand what you're getting at? Have a few different types of knobs lying around, some in aluminium, some in plastic... somewhere. It was this knob that was closest to a box, and then it got the honor of being the first knob!
I've only been building tube amps for a couple years now (I needed something to do during the Pandemic) but I'm pretty sure my ears are not that concerned with the type of knob connected to the volume control, as long as it can turn the shaft 😎
Have built many amplifiers in the last 30 years, and I am amazed at how good it sounds, if you follow certain "rules" such as keeping signal-carrying conductors away from ac voltage, and so on. The amps sounds great. We do not need golden knobs, "expensive "output transformers, and so on... Keep It Simple!
I sold the one I did not have space for. I built Lodstøm's preamp, Remus, based on ecc 82, and ecc83 in the phono stage. Great sound and easy to build. Some ecl 82-86 based on output transformers from old tube radios. Tried myself on some el 84pp, preferably based on different constructions. felt like it wasn't quite where it should be? A few years ago I built Tubelab's el 84 with ecc81 input tubes. It sounded very good, top notch! Some of the best I've heard from tube amps!! Hammond transformers and chokes... There have been some el34, both SE and PP. There must have been close to ten phono stages, and maybe 6 to 7 are still alive. There have been many preamps. 6J5, see there have been some of, 12B4A, ecc 82 srpp there have been 4 to 5 of, some with phono stages, and some without. Have recently built some el 84 SE and some 6V6SE. Some have been sold and some are on shelves here and there. When I've sold a few amps, I suddenly have room on the shelf for one more, and then it's just a matter of starting a new project. As long as there are some output transformers, transformers and chokes, here and there, then it's just a matter of getting started on new projects. Some Nelsom Pass B1, in different versions and some AmpCamp amps has been built and stored...

Most of the people who use amplifiers don't like to turn the volume whitout knob, or see a few empty holes on the panel of a box and won. . A lot is shared about diy amplifier . We can learn good tips.
Chokes are one of the most effective parts in sound quality. In an old radio, choke tubes are often small and made to play the middle sound. They are never able to play low frequencies in the single circuit. Many of them do not have insulation between the layers. . The music that can be recorded is not only the middle sound. I have never used the output choke of the radio. I didn't pay much for the choke, I bought the core and wound it myself.

Never use....... used parts. They may have been changed. It is hard to find similar parts.The sound is different every time. How does our information progress? . Today, the existence of the Internet allows us to learn and do anything. Producing valuable technical content even makes us create jobs for others. ,
I don't quite agree with you when it comes to reuse of old components. Have many times used chokes that have been in old, defective amplifiers, together with transformers. No problem with reuse with them. Chassis can be reused, and it can be done together with switches, but they must be cleaned.... Tubes that have been in an old radio or amplifier very often have many years left....
I may have to open a new thread, I'm about to start building this amp, and first I wanted to simulate it in LTspice, and in the frequency response diagram I get this.
what the hell is that?

I would think that it's self evident. That's a problem with one of your models. No real circuit is ever going to look anything like that.
More than that I can't say. I don't trust most spice simulations. Too many weird bug fixes and inconsistencies in the simulation code.
YMMV

Perfect example of how these computer simulations of tube amps don't = what an actual built amp does.
