looks like the best I can do is about 5.7 inches

current gg board is 4.7 inches

 

Thanks for taking the time to look into that, Kevin.

Will gladly work around the larger dimension on my end (new cases) when this new tube input GG happens.

Got a gut feeling this will be a killer amp!

far too many projects to keep up, but it's always so tempting once you see the artwork...

i remember reading that kevin was championing the el34 ccs in the megatron, should wire that in instead so everyone gets the tube complement they want even if it's not the grounded grid output. kidding of course, even if it does sound monstrous.

Looking good @JoaMat :)

Here's the new schematic with the updated servo.

It would be very much appreciated if some folks could check Kevin's boards against this schematic.  Thanks :)

EDIT:  Updated schematic to match transistor values.

minor differences: board looks good, don't see any problems

board uses resistor + zener string instead of U10

D3 has a 350K resistor to ground

connection of R15 changed  and values of that and R16 adjusted

Q7 Q8 Q9  Q10 are KSA1156 instead of  STN9360 on schematic

trimpot added to R12 for offset

Q13 collector has an added 100k 2W resistor
