48-482 rear panel help - keithchip - 04-10-2025

I've recently finished the internal restoration of a locally purchased Philco 48-482. The cabinet is in ok shape except there is no rear panel.

All is working well and the radio is a good performer. The question is when to stop on the project? I kind of like the "well used" look of the cabinet and am reluctant to refinish. But I would like to have a somewhat realistic rear panel for safety purposes, and to add completeness. Can anyone supply a rear panel photo of a 48-482?

Then there's the question of where I use this radio? The most likely location is for garage entertainment while tinkering on other projects. Should I add a Bluetooth module so make the unit more versatile, or is this sacrilege? It's a moral dilemma!

Thanks in advance for any help with rear panel pictures.

Welcome to the Phorum, keithchip! How far you take a radio on cabinet restoration is a matter of personal preference. Like you, I prefer the 'gently used' look. Several members here take their restorations to "fresh out of the box" condition, and I have no problem with that either. I don't believe the 48-482 came with a back cover, but I may be wrong. I've never seen a photograph with any back. Take care and BE HEALTHY! - Gary

Gary is correct, there was not a rear panel on the 48-482. I restored one of those and its a great sounding radio that recieves FM. Unfortunately the FM1000 tube that was unique to Philco and is required for the set is getting very hard to find.

Thanks for the responses Gary and Bob. I'm a little surprised that there's no back panel - although I know older Philco's were that way. There's a slot in the cabinet at the rear that looks like it could be used to attach a panel - I may make something up to keep hands out.

I was lucky that I got the radio with an operational FM1000 tube - albeit rolling around in the back. The FM discriminator is working pretty well but it's a picky circuit to get to that point. I think my strategy would be to adapt the radio to something else (6BN6?) if the present FM1000 failed.

Many thanks!

Yes, I can confirm. I bought one (haven’t restored it yet) which didn’t have a back panel.

Thanks Joseph. Hope you get to restore your 48-482 before too long!

I also have one of these, again it never had a back, and no trace of one. I have been told that the pushbuttons used to have clear plastic covers, which I though was interesting since other Philco models with similar pushbuttons do not. It's strange because the pushbuttons also have plastic covers over the station tabs like many others do, so it isn't obvious that they are missing anything.

Yup Arran is correct it is missing the pushbutton covers. I don't know where they all go but it's a common issue on this model. Had one back in the 70's It was complete. You might check w/are resource page under knob venders and see if any thing turns up.

Here's a link that will get you to some pics most w/cover and a few topless: https://www.radiomuseum.org/r/philco_48_482.html

Hi Keith, here is an article that covers different FM detector circuits including a section on the theory and alignment of the FM1000!
