Just a reminder for myself too; worn or bad tubes leak heater current to cathode and it gives mains hum 50/60Hz and 100/120Hz. Don’t be me and chase hum from heater wiring, grounding and possibly cold solder joints BEFORE doing some preamp tube roll with known healthy tubes. And be sure your...

Good guess? Dunno if snd and rtn are other way around. Easiest to check if led pwr out from board is 9v or 18v before choosing voltage dropping resistor. Gnd wires are missing from my sketchy sketch.

Short answer: -series coupling cap sizing -bright cap across volume pot (220-470pF) -emitter resistor bypass cap sizing (smaller values give brighter sound) -tone controls cap and resistor values

From what’ve read so far, I wouldn’t say what you’re suggesting isn’t even far away from it. I’ll give a test for the ”germistors” with the lowest leakages and see how compare to the ones on the FF circuit. It’s easy to observe how sound changes when not moving tone shaping knobs on pedal or...

Care to share your observations what changed with leakage? It would be intressing as I just build FF variant and have some lowish hfe Ge’s with leakage varying 50-300uA.

More good or bad guesses! Is D10 orientation right as it’s hard tell it looking your pic? If you jump the relay bypass board, do you get signal?

Leak or dirt on the electrolyte cap circled?

Short or trace mistake on footswitch board if it happened before? LEDs cathode shorting to enclosure via resistive (+10k ohm) path? Only one string maybe? Otherwise clean build and got to hand some respect about playing with fit so tight!

This is nice and your p2p builds keep getting cleaner! Good call on breadboarding beforehand. I really should do that too and give my b-board some use before making ”final” decision with p2p builds. Life’d be easier.

Thought I made a screenshot or saved bookmark about killing oscillations, supply and RF noise in pedals so could someone help me out fill this quick list? 100nF cap from power jack positive lead straight to case feedback cap between OPA output and - legs and hpf cap on transistor BC legs Star...

I’ve been tempted to get Duo-Phase, but deciding between DIY or just getting Behringer clone is hard. Guess cost wise both options are approx same? Happen to know if Behringer is sonically in same game?

I have to admit yours gave me inspiration to get through component lead nest even thought my brain hurted bit. Now I’m doing p2p OPA muff with ultra stoner tone stack. It’s harder. :rolleyes:

Cold joints circled? And on footswitch pcb cold joints and possible bridges?

Drone Master Vero build based on Fuzzlord Effects Rat variant with a footswitch for mid adjustable tone stack. Been using red led mode and non-mid tone stack. Still doubting if I’d fit metal can LM741 back to it. Better than Mosky King Rat and responds nicely to picking dynamics. Morgul Boost...

I forgot to mention my fellow countrymanship. Amazing to get this custom thing cleared, thanks! Now I’m gonna go and get those cheap alucases. :P

I’ve restricted ordering Tayda before as I didn’t know theres option for this with Tayda/DHL. But I’m wondering which point self declariation is available and does DHL bump you with it as package arrives customs? Or is there some secret buttons to press?
