Zenith G730
 

Hello Folks,

We have this Zenith table radio (model G730) which needs some TLC. I do not
have a schematic for it and can't seem to find one. I am wondering:

a) if there might be one available, (I am willing to buy such a thing), or

b) is this the same circuit as the C730 Zenith radio, for which I have a
schematic.

Any help you can offer would be greatly appreciated.

Did you mean to post a photo? If so, it didn't work...

Yes, Axeman the C730 is the same circuit used in the G730 chassis. In fact, the official Sams Photofact shows what appears to be the G730 model,
but it's hard to tell if it's a walnut (veneer) cabinet like outs, due to the B&W picture. I'm betting the "C" means it's just a cherry-finished cabinet. I've used the C730 schematic years ago to re-cap my G730 and have had no problems. Due to the age of the radio, and unrelated to the schematic, my electrostatic tweeter died, and I replaced it w/a conventional tweeter w/crossover. (Even in 1979 replacement electrostaic tweeters were impossible to find.) There are at least a couple of these radios on uTube w/the original electrostatic tweeter apparently still functioning, so I feel slighted. I'm long overdo to replace the selenium rectifier, and have signs that it is surging the plate voltage in the audio stage (19T8 & 35C5), after it warms up. So that's next on the project list.
By the way, what "axe" do you play ?
