[Boatanchors] P&H LA-400 linear

[Ron VE8RT]

Hi Bill,

    the last hamvention I attended was in 2011, when the XYL VE8LT
accompanied me to SeaPac in Oregon.  I picked up my K2/10 and a few other
items while there.  Tube sockets were hard to find, I remember that.
When someone asked me if we'd be back next year I told them that we
could re-equip the station with new gear for the cost of that trip, I
didn't think so.  Yeah, there isn't much in the neighbourhood, maybe in
Edmonton (2 day drive each way).

    Shipping costs within Canada are of course lower than getting
things out of the US, when I can find what I'm looking for.

    I'm not in a hurry, buying or building an amplifier has been on my
list of items I'd like to have for a few years.
