[Amps] Alpha 91b problem

[Alek Petkovic]

Likewise here Rob.

For my friend's amp, before he decided to bite the bullet and buy a new 
transformer, I had two toroidal transformers custom wound. Each had a HV 
winding and the the other voltages were split over the two transformers. 
The combined result being a much more substantial transformer, built for 
50Hz operation. Another friend has a sheetmetal shop, so I had him 
fabricate the box. The connectors were removed from the busted 
transformer and so we had a plug in outboard transformer box ready to 
rock and roll.

I still have the whole kit here. It will probably never get used as I'm 
very unlikely to ever build a tetrode amp.
