[SOLVED] FADER REVERSE not morking

[mg73]

The status mode FADER REVERSE has stopped working,
need to fix that quick.
Button lights up but nothing comes into the monitor channels.
MIX, RECORD and  MASTER CH INPUT FLIP works.
Anyone had similar problem and can point me in the right direction to look for the problem?

Assume you mean the VCA TO MONITOR?

The card in question is the 82E21 in the centre section.
As it switch lights up, at least everything works up until the T4 NAND gate.

Check pin 21 of the 82E21 card, and ensure the status voltage changes when switched.

I would be looking straight at the TR7 BC212. These blow out regularly, and are all over the logic cards.

Thanks for this Anthony!

On my SSL VCA TO MON are named FADER REVERSE... Go figure.Could be that it has Ultimation?

Open upped the center section and measured the T7 and it was ok, measured pin 21 and got 18v when engaged and 12 when not
so all looked fine.
Powered on all channels and now it works?!
So I suspect some random intermitting connections somewhere not sure
but anyway now it works and hopefully will for a long time
but if not I know directly where to look:)

thanks again.
