Hello,

I recently bought a CV-591A, untested. It has some really butchered wiring 
on the mail power transformer, T5. For example, Pin 8 of T5 was jumpered to 
Pin 14 and Pin 2 was jumpered to Pin 7. Pins 7 and 14 are the 5 Volt for the 
rectifier tube (5Y3GT). There was nothing connected to Pin 2, the power 
mains neutral. Very strange. I don't know how it could have worked. I have 
wired it correctly and will do some testing today and try to deterime if the 
transformer is good. Hopefully it is.

What I'm looking for is does anyone know of a source for knobs? I need one 
of the small front panel knobs. Are they Dakware, still being made?

Thank you in advance.

Best,
