[TenTec] Come On Guys

[Lee]

Greetings Gary,

Sorry to hear of your frustration with the Argonaut V.

If you get to the point of parting it out, I can use a volume control 
dual pot.  Mine is beyond repair due a very bent shaft and broken 
internals. (shipping damage!)  I only need the pot but if you would be 
parting at board level only I might be interested in the entire board.


Thanks, 73,

-Lee-
