Realistic STA-90 Back from Shop; Panasonic Make?

Just got this STA-90 back from my tech for a clean up and check over. It sounds absolutely great and looks really cool too. I have never owned a vintage Sansui or Pioneer but this unit gives what I think a very warm sound. We were talking about the various manufacturers that made Realistic receivers over the years. I remember some folks saying this model was possibly made by Sansui or Foster. My tech said no, the STA-90 was made by Panasonic. He said Panasonic made quite a few receivers for other companies. Regardless, for 44 watts/channel this thing really sings.

theres a site online for ratshack lovers you should check it out.when you start talking radio shack your talking about a who,s who of mfg.foster,some say sansui etc.

interesting little side note, foster and fostex are now one and the same and have been for a little while.some people say the sta-90 was a sansui deal,cant prove it though.
