Zenith AM/FM Radio Y832
I have rebuild a Zenith AM/FM radio from 1956 for Maguette. I choosed this one because of the full scale FM band up to 108+ MHz. This is a difference to German and European Radios from this era which had a limited FM band, usually in the 50ties up to 100 MHz.
The Zenith radio has an impressive tube complement, consisting of:
| 6BJ6 | RF Amplifier |
| 6AB4 | AFC |
| 12AT7 | Converter |
| 12BA6 | 1st IF |
| 12BA6 | 2nd IF |
| 12AU6 | Limiter |
| 19T8 | Discriminator, 1st Audio |
| 35C5 | Power Amplifier |
Chassis number is 8Y02, model number is Y832. Thanks to Klaus Bayer and Walter Haring I got the schematic and the alignement instructions:

The Y832 radio is from 1956. It is a AC/DC design for 117V without main transformer. I replaced the old Selen rectifier with a BY500/800 diode and all of the PS caps.
The tuning capabilities are excellent. The radio is doing a really good job to get Maguette's favorite radio station FFN on 101.9 MHz. It is a 3 speaker design which sounds really big.
I'm did a similar Job with another Zenith model of this era, a 117V AC portable with AM/FM, for Maguette's girl friend Heidi. You can find it on my Zenith K725 page.
