My Zenith Black dial, serial number R323950 , according to oldradios.com is a 5644a chassis, and could be a 6S249, 6S254 or 6S256 .

I know the 6S254 is a console, so it must be a 249 or 256.

Can anyone help with a schematic ?

Regards Paul

Hi Paul

I'll send you the schematic for Zenith 5644A chassis. The 6S254 and 6S256 are both consoles. The 6S249 is a chair side. Your serial number matches the chassis. Does it look like someone replaced the chassis in your tombstone? Is there any numbers on the cabinet?

Hi, I would like to obtain a copy of the Zenith 6S254 Schematic.
Right now, I'm cleaning the radio up, inside and out. The radio plays, a little hum, not bad for 70+ years! Would like to see if I can increase the sensitivity a bit, it receives about 20 stations with a 75' antenna.

Thanks,
Ray
