wax poured out!

aardvarkash10 · 19th October 2009, 08:29 AM

bringing up my newly built Hagerman phono stage / pre-amp tonight and the tell tale buzz, followed by a smell and then the oozing of wax out of the PTX... sigh.

One of the dubious pleasures of recycling old parts is the lottery of the first run. Sometimes you win, sometimes... the wax pours out! Still eh, gotta be philosophical about it. More time to finish a quiet red wine now!

Now, where's my box of old PTX's???

I had that a few decades ago with a Philips transformer driving an EZ81 that went short circuit. The tube was replaced and the transformer is still working to this day! I didn't try to get the wax back in.

I think that wins the "most random thread that isn't about what you think it will be about" competition for me. Come to think of it, I didn't even know there was wax in a transformer to pour out, the more you know. Good show.

Modern transformers have no wax, but rather synthetic resin. Which is not always an improvement, since it is impossible to remove if you need to rewind the transformer.
Wax impregnated transformers are so easy to disassemble & repair.
