Well that was most disappointing. I blew up all of the capacitors and was greeted maximally with a “pfft” and that was it. No booms.
Inadequate applied voltage. My preferred means of capacitor grenading involves a salvaged microwave transformer.

Mains AC should help
, see around 22.40 to 27.00 in this Shango066 TV recap video and recapping it did not fix the fault.

I know bd... He
started with mains AC. Now it's time for the
good stuff.

Was 70V DC wrong way round at half an amp. Buggers usually let go fine at that.
Further to us discussing the other day whether you can leave feedback after a case is closed on eBay. I just had to force a refund out of a seller that sent 'not as described' crap (it was what they said, but was so borked as not to fit the description). They tried all the usual crap that it typical of
some Chinese vendors - discount and keep ("no it isn't any use"), emails outside eBay "can't refund with case open" (screen shotted and added to case photos) and so on. So, they are definitely getting negative feedback. They finally caved and refunded - immediately after I copied their external emails outside eBay into the case, funny that.
Anyway, refund has been paid, and this is what it looks like at the moment pre-feedback:
I wonder if people who thought that they couldn't leave feedback simply missed the entry because it had moved to "Returns and Cancelled Orders" or some other sub-category other than the headline "Orders" list.
Negative feedback now successfully left.
all the Tek TM500 modules are popping up recently.
I've got that oscillator too. It's a really smooth device, and its tone is very, very good, plus I like that it's got a balanced output. In the same frame it is paired to a very sick distorsion analyser, an AA501A, but I'm suspecting its no more than aging pains.
What's the trick to get a module out of the frame if the handle is broken?
Edit: Found this thread and subsequently ordered a cable...
I did use the following trick, which is applicable if the remaining part of the lever is visible and functional:
With a pin vise and a small drill bit, a hole is drilled into the plastic of the remaining lever. Then I screwed a plastic screw of sufficient lenght into this hole. In one case, it is still in place, acting as a substitute pull tab. In another case, where the pull tab was found in the package, I used the screw after removal of it's head to repair the pull tab with a matching hole drilled in the broken part and a drip of epoxy adhesive.
The Type 3A74 4 channel vertical plug-in is fixed. The new NTE160 transistor did the trick.
One more plug-in to fix. A Type 3A6 Vertical.
Well that was most disappointing. I blew up all of the capacitors and was greeted maximally with a “pfft” and that was it. No booms.
I am sure I could make these caps blow at 1000 DC once my Keithley 236 arrives and gets upgraded to 237.
Those can run to 100s of watts, so very "tzzzzzzzt".
This reminds me of someone, but quite who momentarily escapes me:
ever tried this ADF4351 with display?
Not doing a Dave .... it is a Tony... does it work for you guys... just trying some stuff...
This is a cool looking mini scope: https://www.ebay.co.uk/itm/264005789638
It's a bit "Star Trek, during the movies but before TNG" looking. Not sure if I like it or loathe it.
As to whether it looks useful or not, I've got to give that a big thumbs up. If it was in the UK at that price I'd be seriously considering dropping the money on it.
Yes indeed. It’s totally “Japan” as well if you know what I mean.

In the words of mnem, "tzzzzzt":

That wee scope you linked is nice, shame it's in the land of mad shipping prices.
Note that the Electrophoresis type supplies are designed for biology lab use and have safety features including earth leakage detection on both positive and negative outputs that make them hard to use as regular power supplies.

I've watched all of two minutes so far, so this isn't anything like a fair summation, or even a comment on the content. BUT, too many "erms", "errs" and "ahhs". I
know that's it's difficult not to do, but the thing is that all those noises that would go unnoticed during a face-to-face conversation
really distract one during watching a recording.
A trick that works for some people is to talk just a little bit slower than normal so that your brain has slightly longer to catch up with what you are trying to say. Like I say, works for some people, not for all. Perhaps try it to camera, play it back and see if it works for you.
My two cents. I'll try and find time to watch the whole thing later and say something a little more constructive (no promises, I've a zillion things to distract me today).
100uf 6.3v x5
10uF 16v x2
47uF 16v x1
22uF 16v x1
All need to be low profile <8mm long. 10uF ones need to be <= 5mm diameter.
Check yours is the same though before hand as there are a few variants with different configurations.
What about the little brown bastards hiding under the display?

No; this isn't what I was talking about. I've had a few such clusterfucks where once the refund was done, the transaction was removed from my purchase history as if it had never happened; I could only bring it up by ticking the "Show Hidden Items" box, and even then, there were no actions available to me.
No idea why, how, or if it is something that has changed in over a year since my last really shitty fleaBay transaction.
