Something Like This:

 

[Coda]

The EffectsLayout schematic is correct aside from a few capacitor values.

I'll have the doc posted by the time the PCB is available (maybe sooner, who knows, let not get too overzealous), no need to start a riot or anything.

I ain’t done nuthin at all…reckon I won’t start with a riot…maybe a TS…

Well okay... but you're gonna feel it when the dance gets hot.

Got to find the reason, reason things went wrong
Got to find a reason why my money's all gone

Wait. This isn't a troubleshooting thread...

 

[Robert]

Give it time...

How consequential are those deviations?

I pull into every thread shootin’ trouble…

@Robert curious what you used for the Ge NPN for Q3?

One is probably noticable, the others maybe not so much. I'll list them in just a bit.

I'm waiting on prototypes but here's the specs of the original:

2SD352
hFE=123 at Ic=5.00mA
Vbe=0.223V at Ib=5.00mA
VceSat=0.016V at Ic=5.0mA and Ib=1.00mA
IcLeak=0.266mA

Referencing the EL schematic:

C2: 150p
C5: 2n2
C8: 10n
C11: 150p
C12: 220n

Q1: 2N6428
Q2: 2N6428
Q3: 2SD352

Also, the Bias control is A250K dual with taper resistors. (Like the schematic posted on FSB)

 

[benny_profane]

C5: 2n2

Is this the one you think might make a difference?

 

[Robert]

C8 is the one that caught my attention.
