Hi,
I'd been following Old Crows instructions but didn't spot those two diagrams Thanks for that, especially the see thru.
Re IC24 IC26 and IC34 - all pins 5s are linked.
The buttons are back except Bank D,Patch 4 and 8 - probably new tacts ?
Patches no longer storing at the moment.
Found dry joint on IC30 Pin 7...
I'll follow the +5 thru and then test again.
Best,
Tone
