Model 20 power transformer
#2

Hi Danny

Unfortunately, no.

You will need a power transformer with a center tapped high voltage winding, a 2.5V center-tapped winding, a 5V winding for the rectifier PLUS another 5V center-tapped winding for your 71A tubes.

I would suggest you consider having Heyboer Transformer custom-wind a replacement for you, if you plan to keep and use the radio.
http://www.heyboertransformers.com/index.shtml

A new transformer for your radio should cost around $100. The advantage of having a new one made is that you can have them design the primary for 125 or even 130 volts AC, instead of the 110-115 volts that the original was designed for. This will reduce the strain of higher than designed voltages on your old radio's circuitry due to today's higher line voltages.

Should you decide to pursue this, you will need the complete specifications for your transformer - physical size, mounting, and the voltages and currents required for each winding. I'll post the transformer specifications later.

Heyboer does excellent work. I've used their services twice so far, and would not hesitate to use them again. But be advised they do not provide a terminal board as the original had, only wire leads. You will either have to adapt the new transformer into the original bells and terminal board, or hook the wires into the radio circuitry, without a terminal board.
