Ask if he’d like to sell it to you for very cheap, or donate it to the channel. Would be cool to see it going. I just finished restoring a 1937 Philco that is similar, the dial and controls face up towards the ceiling and the speaker is forward facing. It’s meant to sit next to a chair.
This is actually a Stewart Warner model 1803 chairside with chassis R-180 from 1938! She needs a little work on the tuner separation to the chassis. Good assessment. Originally had a 5W4-GT rectifier. Nice rare chairside radio JP. Too bad the owner doesn't want it repaired!
NIce assessment. I agree about the mica mold caps. I used to confuse them with mica caps when I first got started. Once I had ruled out everything but one of those and changing it fixed the problem, I learned to the difference. Easy mistake for a beginner. The lack of isolation on the tuning cap is a little more egregious but we all have to learn. I hope you have an appropriate speaker. Enjoy your content, Doc
I had a Philco 38-5B that would motorboat if the tuning condenser was too close to, or too far from the chassis. took a bit of fiddling to find the right thickness of grommets for it.
Power supply caps, B+ bypass caps, may as well replace all the rest of the caps too. Check those resistors. Tune it up if it needs it. EDIT: That floppy tuning cap is probably the source of the motorboating.
Would that magnet have a Hum bucking coil to anti phase the hum, or am i thinking too far in the past?. That radio chassis looks like it came from a table radio. Ooow heat shrink tubing for the capacitor isolation, maybe coax pushed on to the stubs. Thats enough of me thinking lol.
This set is old enough to have an electro-dynamic speaker. The coil would have provided both a magnetic field for the speaker in place of a permanent magnet as well as acted as a choke to kill some of the hum. However, given the phase cancellation effects as part of the speaker, it only does a marginal job at removing the hum with a PM speaker. There really should have been an outboard choke and a little more filtering (50mfd vs the 10mfd that's in there) No matter, the owner does not want to pursue repairs.
FYI: I submitted a work order to the owner, and he'd much rather put the effort into something he likes alot more.
What a shame he wasted your time :-(

that's sad.. not too many chairsides left around.

I worked on a Zenith radio similar to this,it was a table radio like an end table.
Great video. Thank You!

Good idea to lose that 5U4. Double filament current will get that old transformer an unnecessary workout.
Just a thought.......
I thought you were leaving town so I brought my turntable elsewhere or i would have come to you.
I'm not gone until likely late 2024. I'll be looking for a new house in the spring. For now I'm taking in small repairs.
With first generation octal tubes with grid caps, it looks to from the late 1930s, not the 1940s.

Nah that was the radio farting not me ;)
A "car speaker " LMFAO He didn't just so happen have a cable spool for a coffee table, or a transmission servicing in the bath tub, did he?
Sounds like it's got a bad case of gas 😆
