Title: Zenith H-845 Tabletop radio
Post by: Mongojustpawn on October 07, 2014, 03:29:08 PM
I just got this radio today at the thrift shop, model H-845, S-53555, am/fm/fm afc, diagram on case bottom shows 8 tubes, dated 1961, 35 watts, has 2 speakers, sounds pretty decent. Needs cleaned up inside and out.

35 watts is the current draw, I am sure.   Give us the tube complement and we can probably ballpark the output.

I don't see a power transformer, be ware that it s probably a hot chassis.

I read on antiqueradio.com, (I think) that the output is 10 watts, and that the chassis is hot. Here's a tube list, Sylvania 12at7, all Zenith, 35c5, 19t8, 12au6, (2) 12ba6, 6a84, 6bj6.
I pulled the chassis out, for a cleaning and deoxit of controls and tube sockets, put it back together and it still plays. My only functional tube gear.

Good candidate for practice re-capping.  You can also re wire the chassis to make it safer, antique radio sites will show you how.

Thats a 50's radio with ceramic disc caps instead of paper caps.
You may only need to change the filter caps and clean and align it.
I have one and some people thinks its good sounding and some call it an audiophile radio but I think its better than some but not the best i've heard.

Here's a pic of Anders radio from the media section here on the forum.  You can see a lot of his radios there.

Mine has a date stencil I presume of 2/62, on the bottom, as for recapping, my initial foray into restoration has not gone well, and I'm kind of gun shy. Here's a link to my other project.
