Bought a second Tele Studio at a discount, thinking that a parts box would be a good thing to have. Now I'm trying to consolidate the two into one working unit.
I'm testing the top board today because after assembly I only have AM & SW, but no FM for more than a minute or so before it all turns to static. I'm thinking it's a capacitor that's gone bad. I cannot check most of the alignment points because I don't have any way of injecting the signal that's needed. I made some checks around IC 101 with my oscilloscope before losing FM but I don't find anything. I'm also checking some diodes just downstream from the antenna input without finding anything unusual yet.
Anyone have any experience working on these? I have the service manual from the sites downloads section, and I seem to be able to puzzle out enough German to follow along, but short of a recap I seem to have hit a brick wall. It appears this manual is OK for use with the Studio 1 & the Studio 1M.
I have all the boards connected, but no FM going out to the next board it seems. Any help would be greatly appreciated because that and a re-belt seems to be the only thing between me and rocking down the house.
