Looks like my HP-Z3801 got zapped in the lighting storm last night. The
Voltage Converter Assembly appears to be bad. Not yet sure if it got the
mother board also. Are there schematics out there, and can you get
replacement parts for the DC to DC converter package. I have searched the
K8CU pages and of course have the user manual. Would it be possible to
supply the 5/15/-15 volts from and external supply or would that have an
adverse effect on the performance of the oven and oscillator.

Hi Connie
I'm sorry to hear your bad news, let's hope it didn't get the motherboard
too:-(
I've been looking for a spare PSU module for quite a while now without
success.
I did think of just building a separate PSU but was a bit wary as the outer
oven controller is on the power module and I wasn't sure what that involved.
However, I recently came across this web page, which you might find useful...
