Schematic/layout for Standel 20J12 / S-50 -- help with missing values?

[oldmacman]

Hi all,

Based on some gut shots on amps that have been listed for sale, I've put together the following layout/schematic for a Standel 20J12 (combo) / S-50 (head). This is a 2 x 12AX7, 2 x 6BQ5 amp with a 12" Jensen speaker.

There are a few values I'm missing:
* All of the pots
* A few of the cathode bypass caps
* The output tube cathode resistor
* The power and output transformers

Does anyone have access to one of these amps, or more photos that could help me determine these values?

Also, there was a 20J12T version of this amp with tremolo, and none of the photos I've found have a clear enough depiction of the tremolo circuit for me to figure it out. Any info on that would be much appreciated.

Thanks!

I was able to get some more info and detailed photos of a 20J12T to fill in the gaps. Attached are the new revisions for both tremolo and non-tremolo versions.

Here are a few sets of photos from Reverb listings, Instagram, etc.

thanks to all who posted on this. I have a 20J12T 1961 trem version and was unable to locate much outside of this. Happy to use mine to help fill in any gaps as I can
