[ARC5] INFO Wanted: R22 receiver BCB NAV

[Hubert Miller]

So that's how it's done. Some decades back I was offered a slug of Arc Type 12 VHF receivers that all had this treatment.
I wondered how he did it. But I had no interest in VHF.  BTW, I don't think I have ever seen out here at a hamfest, one
of the BC band receivers, and maybe only one Type 12 LF receiver. Where'd they go? I imagine finding the control boxes
is a magnitude more difficult. 
So the VHF receivers I saw, where did the dial come from? Do dials from control boxes fit?
A friend had some kind of Type 12 test set, with cables and connectors and a receiver control box and who knows what.
Very cute set in a wooden box. But about 20 years ago his house burned. Poor maintenance + no insurance = not a formula
for contentment.

True, but the differences between the R-10 and the R-22 are very, very small. I cannot remember what those are right now.

OK. Here is the deal: first of all, the tuning capacitor in that receiver is identical with the tuning capacitor in the BC-453 and the R-23 and R-24 ARC-5 receivers, excepting only that it has no connection for a dial.

Therefore, it is a very simple matter to 1) remove the snout, 2) remove the original tuning capacitor, 3) install the tuning cap from any of the above receivers, 4) add a tuning dial and a knob.

If you look at your receiver, directly under the dial is info, J-4803, which is the nomenclature for that "snout".

As I said, I have a schematic, and that book that David pointed you to has the schematic for the R-10. In any case, that schematic would make working on your R-22 easy.
