Put the jacks and transformer under the preamp board on the chassis belly.
Thanks Taylor. Jacks out of the noise areas.
I dont have a transformer for the reverb because it is a transistor driven reverb.
Attached the schematic for reference:

The stand offs finally arrived, my supplier had them in backorder.
Did the final drillings for reverb in and out jacks.
Little progress:

Made some good progress. This build is more complicated and time consuming but also a lot of fun.

Thats the faraday shield, you can ground it to get extra noise rejection.

It's alive!
Sound, drive, FET, PAB loop and reverb is working.
Little video; phasing is the low quality recording, but you get the idea.

Excellent! I edited your post to fix the 'youtube' linking. It's a bit odd but you just have to use the part after the end of the url, the unique string of characters and nubmers only.
Youtube links come in like 50 million variants, and rather than trying to support them all, this particular just wants you to use the unique part of the video itself.
Sounds like the phone may have done some AGC on on the levels, it had some kind of 'ducking' and compression if I heard right, but otherwise it sounds great! (my guess is that's the phone audio not the amp)

Erwin,
That's great
that sounds like the perfect amp for me
I would love an ODS with built in reverb and a built in loop
I have a reverb tank from a Deuce sat here
not sure I could re model one of my current amps though.
Do you have any more boards?
