Finally got the "Moparola" done. It sounds great.
I wish I had taken "before" pictures--it was a real roach. Lots of rust and some sort of old tar in place of the long ago rotted away rubber dash seal (around the speaker grill there). The capacitors were falling apart. Resistors burnt. Vibrator shot. Only one bad tube though.
I had to remake the dial face as the paint was too far gone to touch up.

cheers

Wow! That looks awesome! Great job. Any car guy would be proud to have that in their dash!

Don't forget to show it at the TRF also...  ;)

Thanks fellas!
I hope he's happy with it. I gave the guy a big discount on labor because he gave me a guy to call who wants to get rid of a room full of tubes. I need some inventory for my tiny LLC's online-retail end of things.

Anyway, I don't have anything pending for in-house work unless a fellow drops off his Fender amp. I am going to start on that AE50!

cheers

Wow, that "Moparola" was built like a tank! From the back it looks like a breadbox Granny used to have! I agree with Dennis--I'd love to hear it play. You do excellent work. Seeing it installed back in the dash of the '49 Plymouth would be great too. That radio was made back in the day when things were made to last.

Thanks Jonathan, that is a true statement this was built like a tank. No welded, chrome plated plastic. Even the dial glass is real glass set into the heavy steel face on small felt strips and held with blued steel band springs. Under the pull of buttons are knurled brass station setting knobs. There is a rubber disc clutch that keeps one from turning the dial knob too far and breaking something...it goes to the end, and slips. Real engineering. (It is a Motorola unit built for Mopar, after all.)

I like to do amps, too. This poor old thing had the wrong cabinet and speaker...some previous owner had built it, apparently.

cheers

If you are into things that have tubes, you could probably use this.

Yeah, no kidding! It looks like it was made out of the ammo rack from an Easy Eight Sherman! :o

That thing looks good enough to sit by itself on a table! I'm not into radios, but that's just beautiful! Great job! ;)

Thanks, guys...Yeah, I am into radio and tubes and stuff.
Finally got started on an AE50 restoration...in my other (only other) thread. I will have pictures of that as I make progress.

That was a very good price! Have you calibrated it?

No, I plugged it in and it powered up that's it. It's now sitting on a shelf in the garage. I'm trying to decide what to do with it.

Well it's a cool unit.  ;D

(You probably already know this, but just in case you don't, or for other readers who don't, one of the worst things you can do to a vintage piece of tube equipment is power it up before replacing the old paper and electrolytic capacitors inside it (and a general checkout). It often destroys any transformer or at least some of the tubes due to leakage or shorts. Electrolytic power filter capacitors don't age well, in particular.)
