Ok chips are secure in their sockets. (3005)

Feeding any signal into the audio in has mic output.

Although, mix to bbd out 100% and the bbd switch at middle, has signal  
out, polarity - or + at full ddb mix has no output.

Note CV2 in is triangle  output of A-145

Delay clock makes no sound or jitter. from any polarity settings on  
bbd, mix or either.

It was working 5 min before i sent the email yesterday, it seems as  
though something has failed internally, maybe ic ?

I only has the A-145 input on cv, it just stopped...

If there is any specific way to test the ic chips and board, let me  
know and i will have a go.
Replacements??

:(

Regards

Michael
