I've been looking for a harmonic distortion meter just to play with for years, but most of them are to expensive for me. Just got a HP 332A yesterday for 20  bucks including shipping  :-+.

It seemed to be in kind of a rough shape cosmetically, but after arrival everything seems to be intact, just dirty. A quick rub with some water & soap revealed it to be pretty nice. It will still need lots of hours of TLC though. It supposedly stopped working about 25 years ago, so it might take some work. I have already checked some caps, and a lot of them seem to be bad.
I didn't even think you could ship it for $20.00. :o

Yeah, that's a good deal, even if it's in need of TLC. Hope you start a thread on its restoration.

I did buy things before where shipping cost 2x the actual item price due to being some obscure piece of boatanchor gear that nobody else wanted.

I keep thinking that I need to find lighter things to collect, but of course it's the old heavy stuff that interests me.  New stuff is blah.

Yeah, huh?  That's quite the deal!  Nice find!  I hope you can get it up and running without too much difficulty.

Sadly, I have no idea what kind of strange mains plug that is - a normal IEC plug doesn't fit, even after trimming the excess plastic of, the slots are just a few millimeters off... Would love to try it out though.

Might be an IEC C10?

Shouldn't be a real problem, just need to replace some caps and the mains cable. Then I can start debugging.

Why not change it for a normal C14 connector? Or a  C18 as the ground connector is unused. I replaced the connector of my HP 332A today. The old one was crusty as hell, and someone glued the cable and connector together. I replaced it with an 30 year old C14 connector. Really looks original, but works nice too.

It's so convenient to use one type of connector on your bench.

I've contemplated modernizing a couple of instruments that have the old PH163. But, the other side of me likes to keep things original. :-//

However, that old C14 looks great and maintains the look and feel of the original. What did you use to enlarge the panel opening?

Just a round and a flat file. Only took a few minutes of work, I even reused the original holes.

Very nice. Yeah, I figured you just enlarged the opening.

Fortunately, I have cables for the few devices that still use PH163. But this'll come in handy for the next one. ;)

I try to keep old stuff as original as possible but this is one area where I'll occasionally make an exception, especially if I don't have the original cord. I hate having to find an obscure power cord, or hook something up with a suicide cord that has alligator clips on it.

Seems legit, thanks.

I thought about that, but as I don't even know if I will ever use it for anything, why should I bother? :)

A couple of Heathkit frequency counters...

Not sure what I'll need two for ...

Sheesh were you at the swap too?

We might have to setup a little meet after one of these events if that was the case.

Unfortunately, I wasn't. I just recognized them from 12voltvid's BARC tour video. So, I had to ask. Now, if I could make a vacation trip to Canada just happen to coincide with such an event (wow, how did that happen?), a meetup would be a hoot. :-+

Yep @ 9:32 in the video.   I wasn't sure if they worked or not, but even if they didn't, they're a really nice case with a 12v transformer inside, and worth it for that. In fact I'm still debating gutting one of them just for the case.

Cool. Although if it does work, you can probably sell it for a nice return. Healthkit stuff tends to fetch a lot of bucks on eBay.

34401A branded Agilent, stamped Jun 2000.

100£ Buy it now on ebay.co.uk. Estimated 130€ shipped to me.

Sold for "repair or parts". Seller wrote something like "Doesnt start up. Illuminate display, beeps twice, turn off".
Couldnt resist and take a risk. Seller was very nice to send it overseas.

Missing mains switch push rod, that plastic part fixing front terminal in place and back plastic frame. Clean internals.
Quite easy repair, repair here.

Fluke 8800A 5.5 digit DMM, ca late 1970's/early 80's.

Super basic as far as DMMs go, this doesn't even have a NULL or REL button. Certainly no math, dB display, min/max, logging, etc. Just DCV, ACV (average responding), and Ohms. It is auto-ranging which is great. It uses a monolithic dual slope converter IC, likely Fluke proprietary, identified in the service manual only as "Part of final assembly". Gee, thanks. I opened it up to check on the two AA batteries that are used to power the current source on the ohms board, and was pleasantly surprised to find none. This one is apparently a later serial number that uses the same ohms board as the 8810A which has an isolated converter rather than batteries. Nice.

DC is spot on all ranges (photo shows 20 V range agreeing rather nicely with a Keithley 2001 7.5 digit meter). AC is accurate and very flat up to a couple hundred kHz. Too bad it's not true RMS (8810A is). Ohms looks accurate too. As you can see I don't need another bench meter (two Keithley 199 and three 2001 visible in the pic, one more 2001 out of frame), but I literally rescued this from the scrap pile at a local electronics recycler. They were purging stuff that had sat around unsold for too long. Paid... don't be mad. $5. Canadian. That's literally its value as e-waste destined for the crusher.

One of those is still on my list.  (those on here who know me will doubtless be shocked to hear that...   :-DD )
