Whats Vintage Testing Equipment Do YOU Have/Use?

[v4lve lover]

That thing is beautiful, i'd take it in a whim if it weren't for the shipping and 230 VAC incomparability.

Old stuff, let me see, I occasionally use my Tek 535A the 545A also gets some use. The rest of my teks are in dire need of repair.

Euhmm, old but solid state, a delta D015-1.5 also a Philips PE4817 35v 10A PSU.
HP6281A for powering heaters on projects.

Then there are the Avometers, which see occasional use measuring voltages which the digital meters can't handle.

I have a new, in box HP 400-D -- i guess it's like having a 1983 Chateau Petrus -- you never want to open it.

The only vintage test equipment I have is an old Hickok 539b tube tester. I paid through the nose for it because cosmetically it was in great shape, but I did have some issues with it that seems to be sorted out now that I got it serviced.

It has served me well over the past few years.

REFUGEE1,I like your megger is it a evershed vignoles ,i have the cabinet to hold it in place
and it is driven by a electric motor.....very rare !

Both are real Megger branded. The company is now owned by AVO.

The wooden one with the AVO 8/9 next to it is made to be used with an external power supply and I have also shown an internal view of it.

I have made up a rechargeable battery from an old tow truck beacon and an old 1980s laptop battery.
It works very well and is quite accurate.

Is your philips PM5130 a beat frequency oscillator? If yes do you have a schematic for it? What is the THD+N floor?

I picked this unit up quite recently. (just for the looks I had to buy it!)
The unit works OK, but can’t say what the schematic is. I suppose it’s a Wienbridge.

 

[audiohead]

I am pretty sure that is a BFO.

I looked for the schematic on line but could not find any.

I always wanted to build a BFO, but never did.

I can`t imagine it would be a BFO since that would be an peculiarly complicated way to build an audio oscillator. Wien bridge was pretty usual in those days.

 

[audiohead]

It is not possible to design a wien bridge generator that covers 3 decades without a range switch!

We need to see more old school test gear ,i think they are just so warm as what
valve audio is ,i wish i had a room full of those old stuff ........i will sleep in the room to !!

My late father purchased this Megger brand new (in the sixties I'd guess).
