Thanks, I'm glad to having it working again too but disappointed that Fulltone never responded.  I guess that the new manufacturing agreement with them probably also means that any warranty work is also out of the question.  I wonder what's going to happen to all those MN3007's he has?

Prior to fixing my TERC, I fixed my TC1210 which turned out to have a faulty BC547 AND a faulty 4013 on one of the Delay Cards.  The experience inspired me to attempt to reverse engineer the calibration process and redesign the card to work with a couple of mn3007 chips rather than the impossible to find mn3010's.  It's a work in progress, but could ultimately lead to recreating the 1210. 

I'm just curious to know if any progress has been made on this?

I have a TERC and recently lost the left output.  I've been doing my best to chase the signal through each of the three "bucket paths" and all looks good, but one of the 4558's (U7) near the output has 7.5V on the B output (pin 7).  My gut tells me that one of the 5457's failed, but a schematic, or even that section of a schematic would be helpful before I feel compelled to pull up the board.

Fulltone hasn't bothered to respond, despite that this unit should still be under warranty.

EDIT:  Found the issue...U7 was bad.  Replaced it and it's all good now.  Still wouldn't mind a schematic if there's one out there though.  Thanks!
