[AMPS] Amp Supply LK-500Z

[rthorne@arn.net (Richard Thorne)]

Hi Folks:

Question.  I have an LK-500ZA that uses a pair of 3-500z's.  I replaced
one tube last year with an Amperex Graphite tube.  Recently when
operating on 10 meters I get the burning smell thing going.  I noticed
that a blue spot appears on the amperex when transmitting and moves
around.  When I'm done transmitting it goes away.

Is this a sign of a bad tube or is it my choke?
