Need to know if anybody could tell me where to get a replacement transformer. The set is in such good cosmetic condition, that I`ve just got to get it up and playing. any info would sure be great !! Thanks in advance.........Mike G.

What is wrong with your original transformer? I have a radio that is similar to this electrically, only a few years newer (1941). It has a similar tube layout. The total amperage draw at the rectifier cathode on mine is 70 MA. Yours should be similar, though I did not look in detail. I am too tired right now. Your diagram as shown on this site is really hard to read. From what I got out of it, though, the high voltage or "B" supply winding puts out 315-0-315 volts, or 630 volts across the entire thing. You want a transformer with similar voltage and amperage ratings. If you do not wish to hunt for an original, here is one that I found. No 315 volt transformers are sold by www.tubesandmore.com as far as I can see. They sell either 300 or 325 volt transformers. 325 volts is ideal for your radio. It will likely operate great with just a hint of more power. A 10 watt wire wound resistor (value to be determined by you experimentally) may be installed in series with the field coil to reduce the voltage appropriately so that readings at all other tubes are accurate. The radio will likely function fine, though, with 10 volts over spec. This transformer is also a vertically mounted transformer. Yours is likely horizontally mounted. Perhaps your shells will fit this transformer so that you can make it look original and mount it horizontally, or perhaps you will have to mount it vertically. Here is the listing, however. You may check www.tubesandmore.com for other transformers if you wish. Also, you never know what you'll find on eBay. Note below that this transformer has more than enough amperage in the high voltage winding, which is good (150 MA).

: Thanks Thomas for the info. The original one is toasted, burned black inside and melted wax run off all around it.I plan to re-cap the entire thing. thanks again............Mike G.
