[Elecraft] KPA500 #181

[Peter Dent]

My KPA500 went together well EXCEPT I could not get isolation between U3 and
the heat spreader but  I continued assembly any way.

Now when I switch on I get 0 HV message in the readout.

BTW the reason for the delay between assembly and this email is that the XYL
and I have just spent a week in VK3 land (Melbourne) Australia..

Any thoughts or suugestions?
