Do I really need this monster?
Since I must have acquired a really bad case of TEA
I placed a bid on a governmental sales of a TDS8000 sampling oscilloscope that supposedly had been used in a scientific research facility and was offered non-functional...whatever that means. I was quite surprised when I received a letter (yes, by snail-mail ) from the sales organization with an invoice, confirming that I got the deal! 300EUR plus tax.
So I rolled the dice and seems I need to do a little repair job or two. $400 USD landed on my door from the USA and only $40 of that with evilbay global for freight instead of $120 cost (seller screwup) So off to the 'shelf' until I find it some time for a little loving and some power.
Valhalla 2500-EP Current Amplifier.
Relay Daughter board has broken stand offs and seems to have relied on the wire and tracks for one of the mounts regardless
Shipping hit to the side frame to be taken up with the seller or just suck it up but worst case some gentle heat and clamping will likely take it out. Much less work than my 740B Handle welding job.

Lucky you, I like the build of this supply. I hadn't heard of Toellner until recently when I stumbled on a F.G. looking for something else.
Would you say they're a kind of Bang & Olufsen of T.E?
Another DMM (a GMC rebrand): LEM Unigor 350 with silicone sleeve, AC current clamp adapter, test leads, carry case and manual for 41€ posted. (+much much patience and determination!)
Good grab. The Gossen Mavo30 will leave me again into a lady engineer's hands, as I shot myself a TekMeter THM560 for 100.-
Got this Toellner Lab power supply from the evil bay. Description said "untested and for parts only", picture showed a pretty much beaten up unit.
Made a lowball offer, and got this:
It's a dual channel 32V / 5A (each channel) supply - and yes it worked out of the box. Needs some slaps with a hammer to make the covers fit again, and new encoders. Will have to figure out how to remove the front panel PCB to see what type they are and then order some new ones.
From my experience, Toellner makes pretty good lab supplies, and some other interesting stuff, so I'm quite happy with it.
What I don't like - they mount a lot of parts using blind rivets. Hope I don't encounter one when removing the front PCB.
Good grab. The Gossen Mavo30 will leave me again into a lady engineer's hands, as I shot myself a TekMeter THM560 for 100.-That was a good deal.
I bought the THM565 a while back a little more.

If you mean 'gold standard' or high end - definitely not. They build solid gear, that did also appear under SIEMENS branding. You seem to think about Rohde & Schwarz (their real stuff, not the HAMEG line). Where Power Supplies are concerned, I would rate them along with Zentro, but not with Heinzinger, delta elektronika or R&S.

Sorry. I don't get it. What was misspelled?

In the listing for your Tektronix THM560, it was spelled Tektronik , might be one reason why you got it so cheap.
