[Boatanchors] driver transformer for Viking 1 modulator

[Al Parker]

Hi John,
	Yes, I think it was a common failure item.  This might not be a lotta 
help, but -- I used the driver xfmr from a parted out DX-100 for either 
a Viking I or a Valiant, can't remember which. So, it's a setup that's 
used in quite a few xmtrs of that vintage.  IIRC the orig. used a xfmr 
with a CT on the secondary, but it is possible to use one without a CT, 
with a balancing ckt (dtls I can't remember but have in notes).
73,
