The Talking Machine Forum — For All Antique Phonographs & Recordings

So today i was browsing a local yard sale and i saw this little table top 78 player from the 40s i'm guessing for $8 bucks! however the back panel where a wiring schematic usually is and all the tubes are missing... for that price im willing to take a gamble to get it up and running. has anyone any information on this machine and where i could find the tubes for it? i would love to see this record player up and running again! Thank you - Tyler

Tube complement might have been
35Z5 (Rectifier)
50L6 (Audio Output)
12SA7
12SK7
12SQ7
These were the typical tube types used in a 5 tube radio chassis of that era.
Look for Riders manuals or Most Often Needed radio schematics, this might be too old for Sams manuals.

That is a really nice clean example, doesn't look too hard to restore.
Of course the old paper and electrolytic caps would need to be repalced.

where would you recommend i buy the tubes from? this is my first repair on anything with tubes so this is new to me

That appears to be a Silvertone 6072 from 1947. You can download the schematic from here:

You might get more discussion over at phonoland.com where there is a forum dedicated to Electric Phongraphs, Radios and Gramophones. This forum (Talking Machine Forum) primarily covers non-electric phonographs.

The tubes you will need are 6SA7GT, 6SK7GT, 6SQ7GT, 6V6GT, and 6X5GT, all fairly common. Be sure to google the "notorious 6X5" (just like that), as that one has a reputation of shorting out and causing lots of other damage. Also, you will most likely have to replace the phono cartridge, or send it out to be rebuilt.

Good luck, and have fun...it looks like a great starter tube set.

Thanks a lot for the schematic Bob, & yeah i know this forum does not really cover this electric phonograph but ive gotten some great information here many times so i figured some phono wiz would know something or 2 about it & thank you for the warning on the 6X5!
