Mike,

If I remember tonight, after I do the rest of the tunings for contest, 
I'll cut up the Yam C7 pinblock I just replaced.

It had been well blackened with _something_ before it arrived here, 
(plate and keys) and I'd kept it almost tunable for years with 
occasional spot applications of CA.  I hope to be able to see amount of 
penetration of both types of living-better-through-chemistry and bring 
segments to the meeting tomorrow.

See you there. Same time; same place.
