I remember those.
It was needed to turn a 2 channel radio in to 4 channel.
I had one of those reverb units.
Made it sound like you were in a tunnel.
Strange
I have old audio stuff around I needed to make room and put a stereo and 40 speakers in my second pole barn . The 1960's Cambridge receiver worked great for 2 hours then started popping and the sound went out . It has been a long time since I worked on anything I am sure I know what is wrong if I take it apart I will probably find some ruined capacitors and fried resistors ... I may even have some on hand from the 1970's . I gave 50 cents for the thing at a yard sale in the 1980's it was an early all transistor receiver with a blown fuse and a few burned out lights couple of hours and a stop at Radio shack and it was back in shape .
I used it up to ten years ago it had great night time AM reception using my house boiler heating units as an antenna. Same in my last house I had it in basement workshop hooked to furnace duct work for AM antenna . FM had separate "normal Antenna also great reception .
When I think back on all the **** I learned in high school it's a wonder I can think at all ! And then my lack of education hasn't hurt me none I can read the writing on the wall.
I see all kinds of old, big name, receivers at a thrift store. Dont know much about them, just the names. Cheap
Those old stereo receivers are great shop/deck stereos. I have one in the shed off my deck that feeds the waterproof speakers out on the deck so I have music when I am working out there. Just restored an old 100 watt RMS per channel receiver for a guy who uses it to feed speakers out around his pool so the kids have music. Has a CD player and a bluetooth adapter so they can play their phones thru it.
