Smaller of the "5000" trio (ST-5000, ST-5130, ST-5150) the 5150 is an excellent 4-gang unit which sold very well.

Japan saw a later ST-5150D version (may 1974) which had a third front switch for multipath display and an additional terminal for FM discriminator output.



Thanks to Lorne in Japan :
"I have just recapped mine. I changed out all the electrolytic capacitors and many of the film types too.
All the values were replaced exactly or close the original. The sound is very, very good. I mean excellent and moreover very natural."
