The 500T is an early transistorized successor to the 500C unit. The early Fisher transistor units had quite a few reliability issues. All the early Fisher SS units I've had have required a bit of work to get them fully reliable. It is not unusual to find one or more transistors to be at, or near, the end, particularly some germanium types. Fortunately, most units mimic the tube units of that era, and have socketed non-output transistors, which makes replacement easier. And they have a large number of small electrolyic capacitors in the sub-50 wv range, all of which should be replaced. Most also have a few early style circuit boards stuffed in them, which have a tendency to suffer from poor solder joints. I am not familiar with the exact complement in the 500T, but it should likely follow that example, similar to the 220T, 440T and 600T. My favorite is the 220T, being dirt cheap, simple in design and operation, easy to fix, relatively attractive and nice sounding with small, efficient speakers. If you are familiar with the tuner circuit topology of the 500C, you should be able to discern the major outlines of the 500T tuner circuits, as the early SS tuners loosely followed the tubed units. Of course, it is best to have a correct schematic.Nevertheless, if you don't have to stuff it full of expensive replacement germanium output transistors, these units can generally be restored inexpensively. The several I've done (mostly 220Ts and a 440T) have come in well under $20 for parts. So, for under $35, that's not such a bad deal. Obviously, if someone else is doing the work, then you may have second thoughts.
These early Fisher SS types sound pretty good for SS, but not up to the level of the earlier tubed models, however. I use mine for background office music, or for kids' and other second systems. They are not junk by any means, and the overall design and construction quality is up to Fisher's standards for that era.
Al the Fisher Doc does handle the early SS units, so would likely have a "RestoPak" or similar more detailed info on your unit.
Good luck!
