Amber Model 7 FM Problems
Posted by mawgui@aol.com on March 2, 2024 at 09:45:53:
I purchased an Amber Model 7 at an on-ground auction several years back. Didn't pay much for it but was hoping for the best because the FMTunerInfo page has good things to say about its sound. Only now am I circling round to see what might be done.
The tuner works great on AM. On FM, the tuner will find a channel and will respond to the tuning buttons when cold. Once it has been on for five minutes or so, the tuner gets stuck on a frequency (currently 88.1) and will not respond to the tuning buttons. Turning it on and off has no effect.
Visual inspection of the interior didn't find any obviously bloated capacitors.
These tuners aren't terribly valuable so a full recap and replacement of semiconductors is not in the cards. But if someone has some specific ideas, it'd be fun to run these to ground. I appreciate your thoughts!
Thanks!
