Bought a few items from the latest PP auction
Weinschel 150W 10dB attenuator
2x Leica GLS 100 lamps - They're missing the light pipes, but I fished a couple of these from a skip a while ago. So all good, assuming the bulbs aren't dead in which case may be a waste of money.
HP 8011A Pulse Generator - (sorry ICETEA) It's a nice little unit, will fit well on the bench.
Narda 150W 3dB attenuator - I do actually need this to go between the output of my 2m radio rig and the input to my amplifier.
HP 5326B Timer/Counter/DVM - I'm a sucker for nixie's
HP8662 Sig Gen - Got a bit carried away, but I do like boat anchors
HP8132A Pulse Generator - Spares or repair, this might be a nightmare/lost cause with all the custom parts inside. Hopefully not, otherwise you might see it for sale again !
Wandel & goltermann SPM-19
Philips PM5132 function generator, which matches nicely with my PM3225 oscilloscope.
NanoVNA and TinySA. I am hopeless for these miniture test equipment gadgets
An inductive amplifier for Eu1,--
A megger but it is over voltage (should be 500V)
A very old megger, you have to crank up the voltage manually. Doesn't work but is a nice heavy paperweight.
Megger
my father had one. get it repaired if u can.
also I want , Philips PM5132 function generator

@RAPo: Megger output voltages are always way off and highly dependent on the load.
I have two working versions of these vintage "crank Meggers". Unfortunately, many of them on offer on ebay are non-working, usually because some idiot saw a voltage scale and tried to measure voltages with them, which instantly destroys the coils. Inside they are extremely interesting though. They have hand wound resistors and the crank cogs are made of some sort of paper/resin mixture to isolate the generator from the crank handle. The case is usually a grained redish bakelite material which also looks cool for display purposes.
But even non-working versions can still be used as a quick and dirty HV voltage source (if accuracy isn't important).

One of mine....
I've got a newer version, the Megger WM4. It works like a charm!

No you don't, trust me you don't.
Its brother the 5131 was my first FG and I couldn't replace it quick enough with a proper AWG and then the Philips sat on the shelf for some years until someone came along that only required a very few basic features..
Want to set an accurate frequency with one of these, just forget it, no way unless you had a counter connected to it at the same time and then watch it drift !
Really you don't want one.

Heh. No worries. For future reference: you can always drop me your username in a PM. I try not to bid against established forum members if I an avoid it. Quite possibly I might not look at the 'other guys' name in the heat of the moment but otherwise I won't bid against you.

They seem to be about £50 to £100 on ebay, so I still got it cheap. It's a shame someone screwed a nameplate into the front panel on that one, but hey ho. I'm going past Aunby next week anyway on my way to Fluke, so I haven't got to pay shipping.

I love analog function generators, lots of dials and buttons to push
The PM5132 has excellent performance for an analog signal generator and it does 30Vpp which is more than most cheap function generators these days.
The PM5132 has a short term drift that is at least one order of magnitude better than that of the PM5131. It's more like Tiny Tim.
Of course you don't use this sort of equipment for stable frequency reference, but it's acutally not that bad either.
I happen to have a counter.
Drift over 500 seconds was 0,036%, which is well within specification.
I also have a PM5193 it's the 'Big Brother' of the PM5131, PM5132 and PM5134. It has a drift that smashes the PM5132 by at least three orders of magnitude when it comes to stability.
It's all good, but sometimes you just need to whistle or need manual pulse width control and in those cases I prefer good old analog stuff.
Thanks for your photos.
The needle of the meter is all over the place.
I have a decent new merger so I'll keep the red thingie as is

The guage in these Meggers are a complicated arrangement. The needle has two coils pulling in opposite directions, comparing the current of the generator (across a resistor) to the returning current. Connecting any source to the meter will fry these coils immediately.

I bought a McGregor mixer amplifier off ebay.
Looked in good condition.
However all volume controls were very scratchy and speaker jack sockets were in poor condition and not making good contact.
It wasnt sold as spares or repair so I complained to seller.
He refunded me and told me to dispose of it.
It probably needs about £30 of components to fix it and maybe an hour or two of time.
So basically beyond economical repair.
I fixed the speaker jack socket and just use it in the house as its not reliable enough for gigs, pots too scratchy.
It is a pig to get open and I cant see how to get front panel out as wooden blocks in the way of removal, so poor design.
Shame as its a nice looking amp with front illumination.
I've got a newer version, the Megger WM4. It works like a charm!
That brings back memory's.Although the version i remember had much more dirt ingrained in it and often an apprentice attached to the clips uttering naughty words as we tried to see how fast you could spin the crank.
The Metrohm 7A501C Safety Tester (not really a megger) have a wide voltage tolerance, see the instructions/specs.
They are intended to test wiring and cables, for resistance between conductors 0-50 Ohms, and to earth, and insulation resistance 0-50 megs.
The load for voltage test is 1 M Ohm.
it uses a ratio so exact voltage is not important.
Beware to use fresh batteries, the red rocker switch may need cleaning.
I acquired two, at Paris Flea markets, EU 5 and EU 13!
Reading 425V and 610V with a 1000V 10 M Ohm Philips DVM.
Despite the voltage variation, both read similar R for 10M or ~ 1M test.
Great units!

Rebonjour, Gigaset C530 IP base, 2 handsets, chargers, EU 7 all.
Great IP phone, used but Like new!
Connected to 100 M fibre modem, POTS RJ13x and Ethernet RJ45X, so both landline and VOIP. Controlled by web.
Fine upgrade....found At Vide Grinier (street sale) in Paris Sunday.

Sick of my kid always stealing my tools (that then I have to search around the full house for them) to disassemble his toy cars I took initiative and:
Now he don't need to steal mine...
And before someone says, yes he is 3 years old, already know how to take off screws and put them back and no, he doesn't use then without our supervision. If he wants, he asks and we are with him while doing it at the table, so also no running with tools in the hand.
