I'll bet everyone of us has done something that was obviously wrong and didn't see it happening. Learn from it. Next project?

Only the first resistor, 6k8, in the power supply looked a bit burnt.
I replaced it with a 3 watt metal. Seems fine so far.

That's what I get for wiring at 1 o'clock in the morning. That will be my second rule. First one is, don't drink so much beer while wiring.

A few more issues with this one:-
1. Tonestack isn't working properly
2. Sounds like I'm playing through an octave pedal

Here's the best part though, went to slide it back into the cabinet, wouldn't go all the way in. Great, what now. It originally had a Twin Reverb transformer, now with the size of the Marshall transformer it hits the speaker frame!
Got to turn it into a head now :roll:

Actually, don't drink any beer. These things can kill you, right?

Check your power supply caps' solder connections. I had the octave effect happen to me one time because I didn't solder the ground connection on the reservoir.

See if you can rotate the speaker. No more beer. Get more sleep. Clear headed is the watch word!

A quick update. All working perfect.

Octave noise fixed - didn't ground the cap :roll:
Fits in the cab - rotated the speaker!
