Need something identified
Can anyone identify this? and is there schematics available for it? it appears to be a Zenith radio power supply/amplifier, but aside from that I dont know.

Date code on one of the caps suggests a manufacture date of 1947, so that is helpful in locating a sams/schematic/model number. Based on that, the Sams would be a double digit sams set (Sams 35-90 or so). ETF has some early Zenith data - check that out as a resource.

The power supply chassis looks like it's from a Zenith Model 12h090.
The chassis number 11c21. The radio had AM, SW, FM1 (old band) and FM2 new band. The Sam's number was 462-20 from July 1946. Last edited by EdKozk2; 01-30-2015 at 05:10 PM. Reason: Removed info due to Sam's index errors. |

Interesting set indeed . I looked at the Nostalgia Air schematic and the first thing that caught my eye was the odd selection of tube base styles used . Exactly one 7 pin mini (6AG5 being used as the RF amp) and one Loctal (7W7 being used as the 2nd IF) with the rest being Octals .
I was also kinda wondering about the single 5Y3 being asked to feed all the tubes' B+ , and do it with enough power to produce decent sound from the pair of 6V6s .... |
