Zenith C-845: no reception on AM or FM

[Jeffhs]

My Zenith C845 AM/FM radio (the set in my avatar) is giving me trouble, and I don't know what may be causing it. I have no reception on either AM or FM (ground buzz on AM, white noise and no stations on FM), though I'd be happy just to get it working again on FM since there's little worth listening to on AM anymore, as in most areas of this country nowadays. I do not have a tube tester or any test equipment except a DMM, and very little room to work on the radio since I live in a very small apartment. I thought about swapping out tubes in the RF sections of the radio (I have a currently non-working Zenith MJ-1035 with many good tubes, most of which are also used in the 845), but I am not sure just replacing tubes will cure the problem. I'll try swapping tubes between the MJ-1035 and the C-845 first, to rule out defective tubes.

If swapping tubes doesn't get the 845 playing again as it once did, however, I don't know what my next step will be, as I do not know anyone in my area who would be willing to look at the set and, as I said, I am in no position to work on the radio myself beyond tube swapping. There is a TV repair shop in the next town south of here, but I'm sure they wouldn't touch a C-845 with a ten foot pole, or even know what one was. That shop deals in TVs, mostly flat screens these days, of course, and would probably turn me down flat if I came in asking them to look at a 53-year-old radio with vacuum tubes.

Thanks for reading this, and for any replies. I don't listen to radio much these days (almost every station in Cleveland is playing that doggone rock and roll or worse), but my C-845 did sound great when it was working (little hum, believe it or not, even after 53 years), so I'd like to get it going again -- if it isn't too far gone.
