Hey Guys,

I've got a TSR-8 that works just fine except one channel won't record unless the DBX is on. Whenever the DBX is off, the volume meter will sometimes max out(armed or not) without any output. I took out the channel card to see if any anything looked wrong. I did not notice any shorts or blown caps. Any ideas?

Thanks
 
You might want to take a similar peek at the dbx card(s) and the switch/relay which turn the dbx on and off for similar issues.

Cheers! :)
 
Thanks for the reply! I swapped it with another card just to see if the card is the problem and it seems to be. the channel i swapped it with was acting the same way. does this mean that i just need to replace the card or could it still be a problem elsewhere?
 
No, if the problem moved with the card, then the card is the issue to address.

Cheers! :)
 
Go over the soldering on the card with a magnifying glass, there could be a solder joint with a hairline crack that is breaking connection when the DBX bypass is selected.

The R/P cards use a IC -LC4966- to switch the DBX in and out.A clue is if the meter peaks then drops back when switching the DBX or arming the track.If that's the case,replace the 4966.
