Hi John,
Thank you again for sharing your version of the scheme. I put your corrections to a clearer drawing

PI cathode resistor (R38) should be 820R, not 920R.....no?

[jabguit]

Sorry - I think you want uf (microfarad) for cap values - not mf (millifarad).

cheers,

In this photo, it looks very light, brighter than the typical grey, but maybe it really is gray. Moreover, 920 is a non-standard value.
Thank you for your comment.

Regarding the capacitors, these are just regional features of the drawing software. In addition, I have never seen millifarad capacitors )))

I updated the pictures

Looks gray to me… Compare it to the white and gray wires.

Does anyone know whether the wiper of the master in the Studio Pro 35 Plus is also wired directly to the send jack?
Is the "reverb in" of the Studio Pro 35 Plus also connected to the return jack?

I kow, it is a long time since this thread was started but I discovered it only yesterday

there is one thing that keep me astonished, the pot values indicated on the Layout

does someone has an explanation about so odd values ?



MANY THANKS

Franco,

My guess with the seemingly odd valued pots is that they are actually as-measured, so the 87kA is for a 100kA nominal pot, etc.

Measured values within tolerance of stated values.
