Richard is correct. May I add that my HP400H, the model
with linear scales,
was full of black plastic encapsulated paper capacitors
(sometimes called
bumblebees or black beauties). These capacitors are
well known for their
failure rates. There may be a reason you got a good
price on your meter.

"Cheap" meaning free is about the best price one can
obtain.

Shouldn't be hard to replace the caps, right? Am I
missing something
here?

Nope, very easy. Just don't use disk ceramics. Something
in a polyester,
or polypropylene would do nicely.

I am curious why you recommend against using disc
ceramics.
BB's are found in a lot of high-quality equipment. They
were supposed to be high-performance deluxe caps when they
were sold but very quickly got a well deserved bad
reputation.
