[Amps] LK-500ZB

[mike stokes]

i picked up a LK-500ZB at a local hamfest.  After getting it home the SN is
only 2 after the one i already own.  It works fine other than the tubes may
be a little weak, with the exception of 15 meters.  The rig shows extremely
high swr on 15 meters  i assume this would be something in the tuned input
circuit..  I am guessing the relay has the highest possibility of failure.
Anyway I appreciate the groups thoughts on the most likely problem.

Thanks in advance
