I haven't done that yet...I'll try to figure out how to opening then without breaking anything.
Sorry, I mistook the selector switch you cleaned up with the Dolby switch. How did you clean up the tarnish on the switch wafers on your selector switch.
Ah haha those...I remove them from the casing and then I let them sit in a contact cleaner solution for potentiometers and used a toothbrush to remove the black thing
One other question. I am looking for a list of caps to recap my 9090db. I had found a list on here before but have been unable to locate it. Do you have a list you would be willing to share?
Yes I used Tom's full recap list. Here you go
Oh, thanks. Yea, that was the one I had seen before, but had not been able to find recently. Did you pretty much follow what was on list?
How is your project coming along?
Yes I followed the list as it is but a few parts where obsolete or outdated so I had to look for replacements following the specs from the list...I used mouser, digi-key, think allied and NewarkElement to get almost everything.
Overall is going well. Everything works but I still have to go over the dolby board and the push switch board that still has the original components
Finally the restoration is coming to an end.
The problem I had with scratchy pots was a dolby board thing, it had a few traces gone so I had to fix that and also all the pass throughs + the recap.
I still don't get the dolby test tone but I don't care cause it's useless nowadays (I think maybe the dolby chips are dead) but I do get clean sound on all inputs.
Here some pics
Great Job on this! Inspiring to us all.
Did you leave tantalums on the F-2655? Looks great so far..
I replaced the elctrolytics, ceramics and the green ones except 2 and I left the tantalums originals..should I replace them??
I replace them... I just forgot the reason... I think it was something like they can get short or something like that.
My amp is working great, but suddenly now I get no lights from the front panel. It started flickering from time to time but today I tuned it on and no lights at all.
Where should I check??
