I don't know but I'll keep an eye opened for you. If you do happen to find one, please post a picture.... do you know where I can still buy core designed isolation transformer (I don't want to build it as I don't have the time to do it and not hobby to build things)?
Here's a good example of this. I picked up these reference tubes from ebay.Beauty of hardware doesn't just come from it's appearance but also it's functionality.
I bought a 500VA Isolation Transformer for research and study (in my country, all transformers are autotransfomers being only 1/5 the cost of the IT) but found out it was shell type which is more efficient. But I want a core type for collection.I don't know but I'll keep an eye opened for you. If you do happen to find one, please post a picture.
"Powdered and rouged"...todays youngsters have no idea what you are talking about. At 75 I do! Somewhere I may still have a "belly-button Brownie"...remember those? Back in the early 50's my Dad and I were on a trip where he returned from the bathroom laughing so hard he was choking on his tobacco chew. I asked what was so funny, and he told me someone had taken the Kodak counter ad-sign that said "Film for your Brownie"...and placed over the toilet paper roll. We both laughed for a 100 miles.Be a day or two to get them all powdered and rouged for the camera.
Don, as you can see by my 65 Mustang I am an old car guy. One thing you may not know is, if you have old hard rubber items, say headphone covers, wipe them generously with lacquer thinner to soften them. It works great on old rubber car parts, like window seals that are no longer available. Afterwards, Armorall helps keep them soft. Phosphoric acid works great on old rusty metal...but don't drop an old Rare 40 Ford rearview mirror in it overnight...next morning glass is all that is left.
Thanks Charlie. I'll certainly keep these in mind.Don, I forgot...Pot metal is not safe around phosphoric acid...which I learned the hard way.
Wow Dave. That's some good looking test equipment. Thanks for thinking of me. Unfortunately I live west of Kansas City, so it would be a fairly long drive for this old man.
Thanks for thinking of me.
one of the hottest summers on record for parts of Australia It's been dreadfulThat and it's really cold this winter.
Yes. The one I have looks like it may have been in a store.I remember when tube testers could be found all over the place, even in grocery stores.
I think that I have the same oscilloscope that's in the background.I was given a B&K Tube Tester panel that was covered with dryed mud. After lots of cleaning I built a wooden box frame for mounting the tube tester on. Here are a couple pictures of this old beauty from around 1959.

The thing works very well so I'll be putting it to good use.
