Median Compressor PCB - Available Now!

[jcpst]

When I did a bit of searching on the T7, it sounds like the processor has been changed over time with varying levels of reliability.

I picked up my 2N5457s from Stomp Box Parts, and they seemed legit based on my tester and it working as expected. This is the one I ended up buying:

Thanks, I might give that tester a try.

I did quickly hook up some jacks and a switch to the pedal, and tried it out for a minute.

It seems to be working, and I have the trim pot set roughly in the middle of its range. Still not quite sure where to set that.

I guess the transistors are fine, because the circuit seems to be working. No idea if they meet the specs written on the build guide, though I installed some sockets so I can swap them out if I need to.

Currently using TL072CP opamps.

So, for now, I suppose I'll drill the enclosure and install everything and play with it some more.

I just don't know how to properly test them without the pricey Peak DCA Meters

There's plenty of information here and elsewhere about testing JFETs without the need to purchase expensive equipment. All you need is a few components and a DMM. Search for the ROG JFET testing method.

Thanks y’all I’ll look at those threads. Here’s a few pics of the build so far.
