Thanks anon/s

I took a transistor from the other board and it’s all working fine now...other than needing an oscilloscope to calibrate it properly, but it’s at least doing what it’s supposed to...sort of.

>You can test a transistor with your Ω meter and a (wet) finger. Connect red (+) lead to collector and black (-) to emitter, meter should show open loop. Now bridge base and collector with your finger. If the transistor is ok the meter should show some resistance. Pic shows how to measure and calculate the approximate current gain B. The 2SC945P should be between 200 and 400.
Thanks. That’s really helpful to know. I’m pretty new to all this so any help is much appreciated. I’m trying to build as much as I can at the moment in the hope I’ll eventually be able to make my own modules.

>Which diy kit is it?
It’s a Din Sync VCF303 Filter Module. Pic related is next on the list for trouble shooting. I’m not really having any luck with filters!
