[Amps] W7RY QSK boards

[Paul Kraemer]

I am looking for W7RY QSK board for the L4B / L7 amplifier or a 
schematic of same.

I have tried a lot of internet searches with no luck.  I have tried 
contacting Jim at the email listed on QRZ with no luck.

Is this product still available?  Not on ebay any more apparently.  
Anyone have one they would sell or share a schematic would be 
appreciated.  I could probably adapt any of the variants of the board 
for other amplifiers.  Seems to have been popular for Heath SB220 and 
others.

Thanks
