In regards to the Superadio three versions have been mentioned. Is the Superadio III the one to go looking for or do the first two models stand out as better stock versions?
What about the RCA RP7887 compared to the older Superadios versions?
I own every model of Superadio except two - the digital one and the new RCA branded model. All are excellent once aligned well. The older models seem to be less likely to need an alignment. The model III seems to be subject to a lot less quality control by the manufacturer and often needs a touch up to work well, but then works as well as the older models.
If I were to buy another right now, I'd look for a Superadio or Superadio II in nice but not excellent shape. It should cost about the same a new RCA model, but be easier to work on or fix should the need arise, and I think they are built a lot tougher too.
I'm always looking for a bargain Superadio, but I mostly buy the boomboxes instead of the standard models because they are rarer and have more features. For example, they all have signal meters even if they are only LED meters, and cassette recorders. And they are all about Superadio II vintage, so they are built like tanks.
For the record, my best performing Superadio is a model III. It's had a performance modification for greater selectivity and I got the tuning dial to track much better than stock. From what I understand, Thompson incorporated the selectivity fix (or at least as close as they were willing to go in a production radio) to their later manufactured Superadio IIIs, but the dials are still an issue.
Anyone have a digital Superadio they want to sell?
