Hi all, hope you are doing well.
Last night i wandered what is the simplest but best sounding amp out there in guitar amp world. I have seen many tube Fender amps that have a simple schematic, but they all have that problem... highs are brittle, and lows aren't punchy enough.
What i am looking for is a simple amp that has a warm tone and punchy lows (could that be achieved?) So i would very much appreciate if you posted a schematic.
I am pretty much a beginner, but i know all basics and i am very interested at this field of electronics. The main reason i want a simple one isn't because i don't know to read "hard" schematics, but because I don't have a lot of money.

The Supro/Gretscth/Valvo amps get a lot of love - see here
e.g. the 6150 is about as simple as it gets, especially if you replace the rectifier with some solid state stuff (And use an earthed chassis)

If you're cheap have a look at some of the techniques used by GWills in his Lamington series of amps - e.g. the SOLO or the LITE

This version has the grid leak bias, the supro with the normal preamp sounds better when overdriven IMHO. The supro super is really a nice beast and as simple as the champ.

Simple amps are often cheap amps. Cheap speaker. Highs are cheaper than lows, so you get a shrill thing. The cure is obvious, though obviously not cheap.

I believe you - I just couldn't find that schematic. Plenty with tremolo or reverb, just no "plain vanilla" ones.
This handdrawn one (no model number, from EL34 world) is about the best I could find.
Any suggestions on model numbers?

In low price section (and simple🙂 The VHT low power tube amp got good reviews, i believe the schematic was available- https://robrobinette.com/Special6UltraMod.htm (not very simple though)
As simple as can be is Fender Champ .... yet it was good enough for Eric Clapton to record Layla 🙂
Check the AX84 site, KILLER simple amps, in all flavours, from simple Champ type to High Gain ones.
And that with the light original 8" speaker .... you will be pleasantly surprised if you hook it to a "good" Eminence, Celestion, Jensen or similar (Weber, Scumback, GWS, Jupiter, etc.) .... let alone a 4x12" .
Here´s a Gibson guitar into a reissue Champ with original light 8" speaker:

judge by yourself 🙂

I've never had the chance to play this amp, so no first-hand experiences, and no comment on the sound quality (I did read good reviews when the amp first became available.)
Looking at the schematic, eleven different switchable values of cathode bypass cap seems a wee bit excessive. 😀
Also, the N-channel, depletion-mode, JFET (all JFETs are depletion mode) shown in the schematic, is actually an N-channel, enhancement-mode, MOSFET. The person who drew the schematic used the wrong symbol.

Sounds to me like f-dur open tuning with 6th string tuned to C. Hardly to compare to well known standard tuning.
Wow this conversation started to go lit after that MH45! Now I am all buzzed up studying that Orgaphon amp... But i am thinking to lower the voltages in that amp if i ever start making one of them because i have a really nice pair of Mullards and i would like to prolong their life because they are extra rare finds that i got for cheap! Wow.. i got lucky
For EL84 fans, Tim Hickey has just finished a Rex Mascot Clone. Volume, Tone, Vintage/modern switch (Si or Tube rectifier) from three tubes: 12AX7 + EL84 + 6V4
+1 on the 12" speaker. can't expect punchy bass from an 8"
this is my take on the champ circuit and it runs into a WGS ET60, before this I built a turbo champ from Tubelab's schematic (found in the hundred dollar chalange about page one or two) this was really quite bassy used a KT88 and WGS G12c/s
