Group - 

Recently aquired the mod deck from a GK400 - all the iron
appears OK - however - the unit arrived here as a box of 
parts and a bare chassis..(sigh)

Does anyone have a digi pix of the under chassis wiring ??
Sure would be a help during re-assembly !!  I checked the
WA5CMI web site but no pix of the underside of the mod
deck. Have also downloaded all the BAMA documents.

I will be subing 811a's for the 5514's - I assume that I need to use
two 6.3 vac xfmrs - one for the audio string - and one for the 811's ???

Also considering using the 6L6 audio design from the 500 instead of
the 6N7/6F6's for a less cluttered chassis - the interstage xfrmr is
a Thordarson T-20D78...not sure if it will match the single ended
6L6 stage properly or not.

Advice and opinions are welcome.

tnx es 73,
