The slide switches on the 5370's use gold plated springs that slide on a PC
board. They are located such that the fan fills them with dust and dirt.
Failures are very common, but easy to fix. You need to disassemble the
switch board and clean everything.
If they were it would be a non issue, know how to do the basic fixes for
those and have multiple donors.
The bad switches on my 5370B are the slide switches on the right, start
sep/com, atten, etc.

damage, nothing major to th
If the switches your talking about are the push buttons or Bill West

List,
I have four 5370b units. Two of the three lost the frequency input
channel while I was using it for long term frequency monitoring. The fourth
unit I bought for “parts or not
working” had the same frequency input problem.
Do we see a trend here?
Verifying that the input switch(s) are
I have 4 5335s, one very nice unit repaired by KN5U, two I repaired
myself and one I am still working one. (2 std, 2 option 40)
The 5334 and 5335 to not use the same style switches as the 5370.
HP liked to re-use parts, except where they did not. This gear comes
from a time when alot more parts
This brings to mind the early 60's. You could go to Arrow Electronics
on Long Island. The had trays of a large variety of ceramic switch
wafers, switch bodies, shafts, bolts, nuts etc. You simply selected
what your needed to build you MxNxP rotary switch..
Yearning for the past.

I haven't looked on mine, but can you drill a 1/4 in hole and patch in
little pb switches? or patch in the common small 4-pin pcb switches?
looks ugly, of course, but...

Hi
Don't know if the switches are compatible, but the 5334 and 5335 are a lot more
common than the 5345 and 5370. For that matter I'd bet there are a bunch of
same era DVM's and such that have switches that might work.

Working on reviving a 5370B, have everything working except the
switches. (multiple switches took impact damage).
So, if anyone has 5370 or 5345 front switch/control board(s) they want
to part with, let me know.
