It has a CT on the 25 volt secondary, and is rated at 1 amp.

Along with a HV transformer. How much leeway do I have in voltage on the HV secondary. 320 VCT with a 6.3 filament winding is also a bit hard to find. I could make a solid state rectifier and rig up some sort of voltage dropping resistor set up, I suppose, if I'm forced to use a higher voltage.  Might actually be better than a 6X5.

I've had this radio for about two years, so its not a giant hurry. I got it originally because it had a phono input and my daughter wanted one that she could use an iPod on. I had a little stereo to mono adapter made up that used Radio Shack mini audio transformers...they don't make the transformers anymore).

it's rated at 100ma not an amp .1amp.

Now I think I've got!
