I own a really old Sencore Cricket transitor/fet checker. You don't have
to identify BCE correctly because it has 6 pushbuttons on it. It's still
a useful tool to check leakage and gain.

Phil, if you want to tell us about Mosfet dv/dt failure or something, just
come straight out with it.

I don't know why you feel the need to set these traps.

But thanks for the heads up anyway.

A good thought.

My local TV repair thinks the high voltage section may be damaged, but
won't speculate as to the cost of repair until I bring in this 90 lb
set and pay a $25 estimate fee.

I found a service manual online that I didn't have to sign my life
away to download. There is a fuse, but it is in series with a 1.5meg
resistor across the AC input. I measure the ohmmage across the power
cord and voila! 1.47 megohms or so. So the fuse is not blown.

Can anyone agree that there must be something wrong with the high
voltage, and speculate how extensive/expensive fixing it might be?

If the "power strip" mentioned is a battery-powered, uninterrupted power
supply (UPS) with surge protection, it may have tripped on the brief service
interruption and not properly returned to AC Line power. The squeal may be
an alarm that the battery is too weak to provide enough power.

Just a thought, since this has been happening to my UPS.

It not only appears to be built by Hickok, it is identical to the Hickok
533(A)
- even down to an identical drawing number (677W). Even the manual is
the
same with the Stark name substituted for Hickok.
