Posts: 439. Location: Knoxville, TN. I made mention of an open 1st audio xfmr (large one) in another thread about the Grebe MU-1 but thought it more appropriate to ask about a replacement or fix for this transformer here. The secondary side is open, giving a reading of "OL" on the Fluke meter. The primary is fine at a little over 600 ohms.

By-passing Defective Audio and IF Transformers
https://antiqueradios.com/chrs/journal/transformers.html
The transformer coupling can usually be replaced by capacitor/resistor coupling often without any loss of performance. In the case of Audio Interstage Transformers, connect a capacitor from the plate of the driving tube to the driven tube grid, The value is not critical. I suggest 0.1 mfd at 400 volts. Then bypass the open winding with a resistor.

Attached to the bell assembly by two screws you will find a coil (which is in fact really a transformer as there are two completely isolated coils which are very close in resistance values for what you need in an AK audio transformer). Remove the entire assembly including the core which ironically looks very close to what is originally in an AK audio transformer!

Exact replacements for audio output transformers in old tube radios are often hard to find. Some of the problem is that there is some competition on the market from the audiophile world. But there is a general purpose multi-Impedance transformer type that has not been "discovered", and is easy to find at modest prices and in new production.

Audio Transformer, its Types and Impedance Ratio
https://circuitdigest.com/tutorial/audio-transformer
Audio Transformer creates isolation between the output speakers or audio circuitry with the transformer’s input side amplifier system. The primary and secondary winding turns ratio fixed to 1:1. Due to this, the transformer does not alter the voltage or current level. It does only create isolation between the Input amplifiers with the output speaker system.
