{Collins} Re: My S'line



And remember never ever bury your gear in a concrete vault in the back yard
with the intent of leaving it to some family member 50 years from now.
(those from Tulsa know what I am talking about) of course that's assuming
SSB will still be around in 2057 or the line voltage won't have gone up
another 20 % on top of what we see today or 60 cycles will still be the
standard frequency of AC power generation or the vacuum in the vacuum tubes
will stood be good after almost 90 + years but I digress.




Thank You
