Re: 36W Turretboard Layout
Looks great! You might want to get those pin 9 wires tighter to each other on the preamp tubes. Personally, I don't solder pin 9 or connect the pin 9 wires until the rest of the socket is wired. Less worry about my iron slipping.

Re: 36W Turretboard Layout
Thanks Josh -- on V2 and V3 the pin 9 wires skirt around pins 4 and 5 to go up the middle (one between pin 3&4 and the other between pin 8 & 9). For V1 I ran it between pins 4 & 5, underneath the solder connection in that little tunnel.

Re: 36W Turretboard Layout
Yes, I see what you did. But you might have noise issues if the pin 9 wires on those 2 valves aren't tighter together, and going up the middle. Maybe not. Keep it in mind if you hear heater noise. Either way, their current position will make soldering the surrounding pins more difficult. Hopefully you can move them out of the way.

Re: 36W Turretboard Layout
Granger amps has a video showing how to melt holes in a Plexi panel with a soldering iron. To add the FX loop I needed 7/16 holes.
Drilled up to 1/4 and then on 5/16, the bit started to chip the hole edges so I switched to the melting method at that point, worked great.

I decided to go with Saul's tube FX loop.

Re: 36W Turretboard Layout
Interesting technique! Personally I use an exacto knife, no drilling needed.

Knife immediately. I cut a cross pattern in the middle, then work around the edge to keep it smooth.

If you think so, you probably shouldn't be allowed around sharp objects.

Re: 36W Turretboard Layout
Looks great. I've always wondered, the Ceriatone layouts always put a high voltage cap across the leads at the rectifier. What's the electrical function of that?

Re: 36W Turretboard Layout
It may be an illusion of forced perspective, but the left-most backup diode on the tube rectifier socket appears to be touching the body of the cap can. Killer job though, very clean.

Thanks for the feedback! Yes that's an illusion, the diode is about a centimeter below the can.

I figured, but thought I would mention it anyway. Better safe than ---POW!----
Looks really good, man. I have iron for a 36W build (scratches chin....)
