Transformer Potting cases

Anyone have any leads as to where some may be found?

I'm looking for one for my toroid of 5.75" diameter.

Thanks!

You may be able to find some cake pans at a hardware or department store with those dimensions.

Hi,

Got an east Indian store in town? They have shiny stainless pans and stuff that may fit the bill.

Cheers!

You are kidding, right? :o

An ethnic store run by people from India. They import stuff, mostly spices and vegetables, but also inexpensive stainless goods that's on par with high-end department stores for quality.

Cheers!

Nope, not kidding.... Remember seeing one in Toronto about 10 years ago kiddy corner from the Green Giants' urinal... but none down here in the States.

anyways............ Found a Wilton aluminum cake pan 6" diameter and 3" tall with flat sides for a whole $10. Right on Amazon. Perfect size for my taffo. I'll JBwels some studs to the inside diameter so I can mount it to the chassis. Just have to find some themaly conductive potting material with some mechanical damping/absorbion.. not that toroids buzz, so not to trap heat within the structure

Hello Jeff,

I was not going to reply because typically the guys here are more tube adept, but I'm an odd bird and look at things everywhere I go for speakers and amps. Target sells a few different sugar containers or salt, flour whatever women do with those things Yellow_Light_Colorz_PDT_02

Anyway, there are several and a few of them are perfect for your application. I'm going to do the same soon when I rebuild my KT88 amplifier. My thoughts are to tap and drill the bolt through the cover and insert the tranny with a few small blocks of wood to keep it off the top part. Your local automotive store sells door edge guard in black. I was going to cover up the cut edge (as you will have to cut it or else waste a lot of epoxy) with the door edge guard and then case the epoxy. Should make you a nice potted toroid with a mounting bolt in the center.

My .02,

Blair

That's too bad... I think I'd starve without them Yellow_Light_Colorz_PDT_04

Right on! Hope it works great for you :)

Probably any "southeast Asian" store would also have these stainless pots and pans. Some folks at Bottlehead got their "trannie covers" at Ikea, though I've never been to one of those shops, so I can't vouch for what may be available.

The toroid doesn't really have to be "potted" inside the can / shield, but there is a major caveat:

If you do put a metal can / shield over a toroid, be careful not to create a "shorted turn" with the mounting bolt. So the bolt can't penetrate and contact the shield, if the shield is in contact with the chassis. This can and will cause serious electrical problems, real quick... Hopefully, onlu blown fuses, and not worse...) :o
