Is there an AC version similar to a 37-624?

[davemc]

Does anyone know if there is an AC version of the 37-624, a 6-tube 6-volt DC farm set? It has a complex 3 section bandswitch, and a very high build quality. I restored a 37-624 - one of my favorite restorations (and very complex). Here is the after restoration photo, in case someone recalls a similar AC set:



Thanks!

Yes - Model 37-620.

Congrats on the restore. Did you restuff the paper caps?

Yes, all capacitors were restuffed. The radio was all original when received. I always try and retain all originality possible. I have the time! And it's a hobby, not a business. Here's my restoration log for that radio.

I've been told I was crazy to dig out the tar on the old "speed boats" and put new caps & resistors inside vs. clipping leads and doing the replacement externally. But you are the first I've known to "re-stuff" the small capacitors. I'd like to start doing that. Could you explain the process, please? Thanks, David

An excellent tutorial on this subject may be found here, on Chuck's site:

I think David is asking about the paper tubular caps. Once removed use a heat gun to heat the wax. Hold on to it with a rag grab one of the leads with pliers and pull. the innards will slide out leaving just the paper tube. I just slip the replacement cap inside without sealing up the ends. Some guys will use hot glue over the ends of the tube.

I re-stuffed the paper caps on one radio I restored by using my drill press to drill out the innards from one end and after putting the new smaller part inside, I hot waxed the open end. Then I re-dipped each cap in melted wax that I got from a craft store so they looked original. That was a lot of work and I'll not do it again.

What type of wax did you use? I tried once to dip restuffed caps in paraffin from a melted candle, but that did not work too well. Did you use beeswax? I normally clean off the existing wax on the outside of the caps before restuffing, since in most cases it is very dirty and grungy. I heat it up using a small alcohol lamp or heat gun and wipe it off using paper towels.

Yeah, I also heated most of the old wax off ans then cleaned the paper tube lightly with lacquer thinner before dipping in new wax. I got a beeswax formulation form Michael's craft store. It comes in a block that appears opaque white but when melted becomes clear. I have attached a photo of the chassis underside while I was working on it.
