Tim,

I found the A-K transformer, unfortunately the dimensions are wrong,

It is 2-1/2" diameter and 3" high, ratio is 5:1 at 2khz, DC resistance is 1k primary and 8k secondary.

This is a good 1st audio transformer but the physical diameter may collide with the detector tube socket.

I would login to Antique Radio Forum, they get a lot more traffic for battery radio sets and post a WTB. There are several avid A-K collectors with parts sets.

Be better off with an OEM transformer but you still need a case with a dud if you can't get two good ones.
