They have definitely risen in price on Mouser in the past few years, but I recently saw Tayda is carrying them now for 0.49 each and they have a pretty good stock at the moment, if that helps! https://www.taydaelectronics.com/wima-mks2-1uf-50v-10-polyester-film-box-type-capacitor.html You could...

I try to avoid sockets for transistors, even germaniums. With IC sockets, you have the outward pressure of each parallel side pressing evenly against each row of sockets, which keeps them seated securely, but transistors don't have that advantage and can very easily come loose. I would try...

The calibration process has you insert the test signal into pin 13 of IC10, which is the same as the pads marked "TEST". If you're inserting it there instead of the input jack, then the issue is somewhere between the input jack and IC10. That doesn't narrow it down much, but it does rule out the...

Just to be clear, you restored the 1M or 2.2M RPD resistor, right? Because 100R is going to almost completely kill the signal before it gets to the first op-amp... we definitely do not want that! How did it bias? Were you able to get the target voltages from the build doc?

Truly thrilling to hear this and it's a lot of why I do what I do. And believe me, I also learned a whole lot during the development... it was definitely biting off more than I could chew at the time, but (provided it is paired with tenacity) it's the best way to learn, in the same way that...

I didn't see this or the other related threads when they were first posted - but reading through each of them I just want to say in the cheesiest way possible, I'M REALLY PROUD OF YOU ALL! I really do appreciate the spirit of trying to figure out the issue rather than going straight to assuming...
