A bit of a change from guitars and amps on this project.
I have a whole slew of vintage radios. Quite a few are restored, but I also have quite a few in the project queue, but they keep getting spurned! Here's one that shouldn't take much effort.
There were 4 variants of this radio - the H845E, L, W, and Y. They all share the same chassis (Zenith's number for the chassis is 8H20), but have different cabinets.
That vertical dial was seen on a lot of Zenith sets from the 60s into the 70s.
And of course, this is one of the last tube sets Zenith made. Its lineage goes back to the late 1940s with the well-known bakelite AM-FM sets. The circuits on all of these Zeniths are more or less identical.
First thing is to take off the back panel.
It's straightforward - there are four 1/4 inch screws holding it on.
You can see how I labelled the leads for future reassembly. I like to use solder wick to get all the old solder off - this way I'll be soldering to a clean connection later.
I didn't photograph the next step - which is to remove the control knobs from the front. They just pull off their shafts.
The red arrow points to the Mallory FP filter capacitor can. I'll be removing and restuffing it with modern Panasonic capacitors.
The blue arrow points to the selenium rectifier. I'm going to bypass that with a modern silicon 1N4007 diode. The selenium rectifiers have a reputation for going bad, so I always remove them from the circuit.
I will leave the selenium on for looks - no reason to remove it.
This radio has never been serviced. I like 'em this way.
Not only that, all of the tubes are the original Zenith-labelled ones. It's relatively rare to find a set with all original tubes.
