1933 Cathedral Model 89B
#3

I agree, it's a great little performer. Nice looking cabinet!

But it can be an absolute bear to get working, especially if you have a 36 tube based oscillator. A bit of advice, stick close to the schematic in that area except for he 36 cathode resistor, change it to 8k6 or so.
You will likely have to rewind at least part of the oscillator coil as well, be careful and precise. I had to do mine four times before it worked well.

Good luck!
Will
