I recently picked up a TRC-431 that had D506 and D507 removed as part of the
modulation mod. I would like to undo this so I can troubleshoot some issues
but can not find any info on what type of diodes need to be reinstalled.
The original diodes were totally cut out so I am stuck without a schematic.
Any help would be appreciated.
Thanks!




Hi.

Go on the radio shack website. You might be able to download the manual
with the schematic. If not, give them a call and ask them. NOT the
stores, you will get blank looks.
Call the main place (tech support) , I think it's in Texas. Not sure
though.
