I will confer with my electrician as I just had major electrical upgrade
completed in January. I was planning to get a dedicated 240V line installed
anyway.

What isn't mentioned is the fact that MOVs are rated by the TOTAL energy
in Joules that they will absorb in their lifetime before they fail. The
energy absorbed from spikes is cumulative and when the rating is
exceeded, boom.
They are also responsible for nasty noise generated by the crowbar

Thanks, Jim for the advice. Appreciate it.

It means nothing. Shunt mode surge protectors (MOVs) at branch outlets
can cause more problems than they solve. The only safe place for an MOV

Jim & Crew,
I bought new 4070 joule APC surge protectors with $150k guarantee (whatever
that means). A fellow colleague responded to me separately about the issue with
the 6m preamp and I am sorting out deal. It appears that the preamp may not

Thanks for the information. I will make sure to do a full diagnostic tomorrow
on the power supplies and strips.

May not have been your radio at all, but instead might have been a
"surge protected" multiple AC outlet box. I have a few Tripp-Lite
"Isobar" outlet boxes, and if they "catch" a surge, they will make a
VERY loud bang! Fooled me for a while until I figured out what was
happening. Sounds like
I did deenergize the equipment during the install. Anyway, something is wrong
and more troubleshooting is needed.

Hi Mark,
There is nothing physical like burn or open visible to the eye.I will probably
try connecting it to an external power supply and see if that fixes the issue.
Whatever happened it was loud. I wonder if the Y connectors are flawed because
I was also going to hook up my LP Panadapter lat
You could open it up and see if any 'spare' parts fall out, or if any
of the components on the board look like they have let out their magic
smoke. Missing/blackened traces on the PC board would also be a
telltale sign.
(I am assuming that any failure that actually created a loud noise

I am a bit embarrassed about something that just happened in my shack because i
think i just blew up my external 6m preamp.
I was putting in line my six meter preamp and using a db15 Y connector with my
