Hi Boy’s and Girl’s
Need some help with information and a schematic for a Highboy I got at a Radio Auction. It’s a real nice Highboy, no missing parts, no broken cabinet parts, has 2 doors that swing open and 7 tubes (2 are missing)
It is a CAPITOL RADIO CORP, and made in Chicago and looks to be somewhere around 1929-1931 by the looks of the chassis. I can’t see a model #, just a Ser. # I have not taken it out of the cabinet yet. The only thing I can find on the schematic is a Capitol radio for a round 1950’s for table and record player models. Not even close!!

Hi,
There are a few CRC models, but appear to be just midget type chasis.

On a simple bet, the missing tubes are likely to be "45's", if 4 pin or "47's" if 5 pin. Unless Norm, or Don have something, this may end up being an orphan.

A quick test if the sockets are not marked, check to see if you get a modest resistance between pin 2 of both of missing tubes.

Filter caps "may" be passable, but most likely dried out just enough to simply warrant replacement. I would also consider looking at putting some current limiting resistors in the plate circuit, as you may have higher than expected plate voltages for the output tubes.

Hi Rick, That sounds like a nice find. I can't see any schematics or other information for it. Can you please list all the tubes left in it and where do the missing tubes seem to fit i.e. rectifier, output, RF, etc.? If you can supply some details I'll try and guess the likely missing tubes and find a similar schematic to work off.
Don Black.
