Thought I might straighten this one out a little as the build doc is entirely Distortion+ MXR Distortion+ Resistors: R1 - 10K R2 - 1M R3 - 4K7 R4 - 10K R5 - 1M R6 - 1M R7 - 1M R8 - 4K7* Capacitors: C1 - 1n C2 - 10n C3 - 47n C4 - 1u C5 - 1n C6 - 1u C7 - 47u* Semiconductors: IC1 - LM741 D1 -...

well ... kinda depends. if I had a single op amp in mind, like a 741 ... then I'm all about design 2. if I have a bunch of tl072, I'm going with door # 1. technically pulldown can be on either the in or the out so it doesn't really matter does it?

well fuck me ... three whole successful builds ... where's the ignore button?

I always considered building one then nobody ever stocked them.

a note about klon diodes ... the original trace measurements (350 mV) were taken at 5 mA ... if you're measuring with a typical multimeter, you're probably testing at 1 mA and so your Vf should be lower ... how much lower depends on the performance curve of the diode (If/Vf) ... ballparking of...

for starters, move the input wire so that the route doesn't cross under the board. then I would move on to verifying that jack ground has continuity with power ground has continuity with all the board grounds ... then all the points in the schematic that go to ground ... also, there's no real...

I should have expanded on this some ... I went out and purchased a small lot of both the kt3102e transistors and the kd521a from the russian federation a few years back ... I was expecting the transistors to test higher as the shared forum knowledge has them between 400 - 1K of hfe making the...

the diodes tested out at .525V at 1mA (closest would be 1N400x rectifier diodes) and the hfe was averaging in the neighborhood of 350 which is lower than 2N5088 but higher than 2N3904 ... depending on how they test out, 2N4401 and BC547 are probable candidates

the soviet transistors are lower gain and the diodes have a lower Vf ... these are fairly important details

those are awesome pedals, glad you got yours finished!

the only input I intend to provide is to remind you that the lowest Vf wins in this configuration. Depending on how you wire your MOSFETs, you'll either end up with essentially a 1N914+1n34 in series (usually comes out to Vf of 0.9V to 1.0V) or as a true MOSFET in which case your Vf may be...

should be fine

if I were in the market for a desktop amp I'd probably buy the Kustom Defender 5H or 5H Mod and run it to a small cab under the desk

I wouldn't use anything stronger than paper towels and alcohol wipes just because you don't want to drive or thin this stuff out and migrate it inside

keep in mind that power supplies will measure high with no load on them ... if it is an unregulated supply it can run high if the supply from the wall is high ... for instance if the power specs are at 110 or 115 VAC and your wall is 120 your mileage will vary towards the high side

yeah ... that's absurd and I'd honestly be offended if you wasted the time trying to shrink the format down to ludicrous levels

I counted up the knobs on the 5f6a, your logic is flawless
