Re: HP-608A Repair

Some years ago, I was at a ham flea-market and found a nice Tek scope cart.
I asked how much, and was told that I had to take "this" with it, and it was
$25. "This" was an HP608E. So I took it. The 608 works, except there is
something flaky in the attenuator. (I really don't understand that,
since the
attenuator depends on physics, not resistors or pots, but anyway. . . .

The sliding part of the attenuator has a couple of 53 ohm resistors and a variable capacitor in it. It may or may not be possible to get the thing apart to replace them. In any case it would be a lot of work.

HP 608D's are good units, just big. If you are going to use it and
space is not a problem, by all means fix it if you do not have to spend
too much.

But keep in mind the market for these is very slow and they do not bring
much anymore. Most people don't have the space and newer smaller design
seem to have pushed them aside. Not that they are any better, just
smaller.

I have one I keep for a back up, but use the two HP8656A's I have most
of the time (smaller, easier to setup, little warm up time). I think I
gave only $75 for mine several years ago. Not sure it would bring that
now.

At least that is what the market looks like in my world.

Hope this helps.
