Well that was quick, and informative . SS - solid-state, Doh!

Like I said, its been awhile...

Anyway, thats why I like this list. Everyone is extremely helpful and
the info is great.

John, Al, thanks again and hopefully I'll get upgraded soon (Tech+ now)
and talk to you all soon from the HT-37. I have a nice (other than
paint), working, SX-122 to go with it. They should both look very cool
with an old straight key I use and the D-104.

Thanks.

John C.
