Default My screwup = free PCBs...

So... I've been working on a PCB for a push-pull driver using a triple-triode compactron tube.

Somehow, I sent the wrong version out to fab. It should work fine - I have NOT built it - but its missing a couple of features that I intended it to have, like an AC balance pot, and a CCS in the tail of the diff amp.

So, I have about 50 of these boards that I do not intend to use.

I'll give them away to anybody that wants them. Limit of 4 boards per person. Free! Although if you're outside the US I might ask you to pay for the shipping...

If you're interested, send me an email (the PM function is not the best way for me, sometimes I get no notifications). pmillett at hotmail works.

I'll attach a picture of the PCB, and the schematic. Hopefully they are readable.

Sorry, you're mostly on your own with this one, since I haven't even built it. I don't really have the time to help much with it.

Ditto witrh the above. Requesting a pair.
There cannot, and never will be, any progress in society, vis-a-vis racism, so long as the concept of celebrating Diversity -- in it's current, politically-correct, deliberate, punitively extractive form -- continues.
