Title: TR 26 logic card 82E12
Post by: christiancarvin on February 19, 2014, 06:23:17 PM

TR 26 is missing on 82E12 and when I fill with a BC212 then all leds on module have very low intensity light and solo and cut don't work anymore.
I've seen on schematics that TR26 is related to RC4 (channel input cut).
My question why channel cut is working while TR26 is missing?

Thanks!

With transistors like BC184 BC212, you really have to be careful.. make sure you have the right type

The BC212LB pinout is E C B, whilst the BC212B is C B E
