rds-8000 repair question | rds 7.6 mod

[adam <submersible@worldnet.att.net>]

Hello,

I have an rds-8000 i just picked up on ebay. The unit allows a clean signal
to pass through but no delay. I'm familiar with the layout so it's not a
question of user error (Proud rds 7.6 and the pds-8000 owner since the 
early
90s). The box also has a noticeable hum. Any similiar prblems from RDS
users? Any suggestions? quick fixes? Nothing seems out of place on the 
board
(no sketchy solder joints or loose chips). I'd take it to the local
authorized digitech repair but i was burned on an amp repair at that joint.
Never again!

Thanks for all the 7.6 MOD input! I ripped it open and manage to coax 26
seconds out of it before the signal quality went below what I doing. I did
set the pot on the max (maybe 35-40 seconds) for awhile and looped a few
bits. Some of the craziest ring mod/ bit reduction sounds i've ever heard!
Yes, I did record them!

Thanks again!

Adam
