I like the JJs. I have used them in Marshall 18W clones and AC15 clones with excellent results.

That looks amazing! I've only ever built on tag or turret board, never PCB for an amp. I'm a tinkerer though so turrets really suit me. If I was to build something where I was certain of parts values something what you have done here would be killer. As for drilling tube socket holes, you...

That makes sense. I really wondered where it was used!

I think there comes a time when we all could use some BAT41s. I should have said - lovely job as always Michael. I wouldn't mind trying this one - I love the LPD68.

This surgical tubing we all use in Fender style guitars - is it really surgical? Where do surgeons use it? Is it what they use in a triple bypass surgery?

If you see how the original Timmys were made you'll see that it was easy to solder one end of each diode to the board and just twist all the other ends together and solder 'em together. Maybe it was a time-saving thing that sounded "subtly better"?

Saul Lochran?? I went to school with him! Damn... I wonder how he's doing?

And here's me just using BAT41s wherever it says to use Ge diodes..

Even better then! As long as they sound good silicon is even better than Ge in my book.

And the MID pot in a Super is 10K. I like the Marshall tone stack better!

BTW if anyone wants to make a four knob version of this I can verify that the tone stack I posted above works perfectly. It sounds like the regular version with MID at just past noon, which is where I park it most of the time. Same principal as a Deluxe Reverb tone stack Vs a Super Reverb Trem...

From building amps I have seen this kind of tone stack a lot! The .022µF caps, the 500-ish pF treble cap, the 33K slope resistor - these are all Marshall changes to the '59 5F6-A schematic. Marshall altered the 56K slope resistor and 250pF treble cap of the 5F6-A Bassman schematic to fatten up a...

And thanks for the updated version. I will obviously have to try that one too!

I find the MID control fairly mild - I don't really like it below noon. I'm even planning on trying a version with a fixed mid. Chuck, Would this work?

Any clues as to what the Chinese looking writing says?
