Hi.
We had a Marconi 6960 power meter power inlet filter do exactly the same
here a few months ago... As you say, a nasty mess... Wasn't a
Schaffner filter though...
Just cleanup the mess and replace the filter with a like replacement,
they are all made to a similar specification. There

Hi Nigel,
The filter is an FN372 2A unit. This is a common failure. It's due to the
particular type of epoxy cased, self-healing capacitor used in the filter. The
case encapsulation cracks and if the unit is left in storage damp gets in. The
self healing is by the metal coating that forms the

Don't laugh, I bought a can of isoprop and some citrus label remover the
other day, they were delivered with a total of ten sheets of paper with MSDS
information - argh!

Its certainly not restricted to the Solartron 7150, I have had the same result
with an HP 436A (late model) which has an open power line filter wired
directly to the IEC power line socket, and its the Rifa 250 volt AC rated
capacitor, which sits across the power line that fails in a very

In the late 70's / early to mid 80's this has been a common failure in
Euopean colour TV sets. Some even caused larger fires.
The culprit was a potted yellow ITT AC filter cap. The TV manufactureres
just sent you bags of grey ones that were supposed to avoid that problem.
Fortunately (remember

As have I, in my Farnell 60A bench supply it took several weeks before
the leakage was enough to show itself as a real fault but not before

Nigel, I assume you have a flexy rubber screwdriver?? Those nasty steel
pointed ones are very dangerous!! :-))

I got one of them from one of those Chinese eBay sources. Hooked it up, let
it warm up,it does get rather warm to the touch. Problem is that I can't get
it on 10 MHz. Even if I connect the control voltage input directly to the
reference voltage out, it is still low by about 4 Hz. Another thing,
I looked up the specifications to be sure, they state a steady state current
of less than 350 mA after warm up. Also, after about 10 minutes, it is too
hot to touch. Definitely bad. I am going to contact the seller.Thanks

Does anyone have a spare, acrylic, red plastic LED display
cover that they want to part with. I just purchased my 5370B
and this plastic piece is badly cracked.
Thanks
