In addition, check out my earlier video and others where I introduce the Simplex, model PB mini-cathedral dual-band receiver I acquired about nine years back that's been in storage. The seller at the time told me the radio was from a family in the Charleston, SC area; other than that, I don't have any other information on the history of the receiver with the exception of the Simplex factory was located in Philadelphia, PA then later moved to Sandusky, OH where the company was purchased by Philco and the plant was closed shortly after.

I watch your channel a lot , I respect your ability and knowledge, I have radios myself, and work on them. Hopefully this interest in the hobby will continue with the new generation.

[@RestoreOldRadios]

I hope so too. Thank you for your kind words and for taking time to reach out. All the best. Don

I love everyone of your videos, I just wish they were longer.

[@RestoreOldRadios]

Thank you for your kind words. I’ll keep the longer videos in mind. Best, Don

Hey Don, Tuning cap came out nice. Looking good. Glad to see you back at it again. :)

[@RestoreOldRadios]

Thank you Doug, I’m slowly getting back to it. I got real sick back in early January and shortly after my mother-in-law passed unexpectedly, then both of my parents were hospitalized at the same time; they are both back home now, so the last few months have been busy handling… Thanks again for your kind words and I hope this finds you doing well. Best, Don

[@RestoreOldRadios]

[@RestoreOldRadios]

Thank you Jim. Some life issues since the first of year has had me sidelined. Hope to wrap up on the chassis soon and transition to the cabinet before summer gets here. Best, Don

The question that always preys on my mind in rust treatments like this is, "how long was it in the citric acid/ultrasonic cleaner?" And thanks for the video. Cap looks great.

[@RestoreOldRadios]

Thanks for watching. No set time as it depends on the amount of rust. Citric acid works best for surface rust. For the power transformer housing, it took 2 days for one section and the other 4 days. The IF cans took less than 1 day. Hope this helps. Thanks again for your kind words. Best, Don

Do you find you have to treat the metal parts with anything after cleaning with citric acid? I recently did some steel speaker grilles, and they would start to form a fine rust coating within minutes after being in the atmosphere

[@RestoreOldRadios]

I typically use one of the following: Rust Inhibitors kzbin.info/www/bejne/aqWTfpynhrCMkNk Hope this helps. Best, Don

WD40 also works in addition to Mothers Mag and Aluminum Polish. Best, Don
