Rust On The Transformers?

If you bought an amp described as "mint, never gigged or used outside the studio" would you still consider it mint if the transformers had some rust on them. Not a lot of rust or corrosion, but enough for it to look like it's been in some humid weather. I've had amps at home and the shop for years that never had any rust no the transformers, and I've had amps that I've taken out to practice and gigs that developed rust.

So what do you think? Was the guy lying about not taking using it outside of the studio/home? Does rust on the transformers mean anything?
 
this may sound stupid - but rust on transformers is actually good for them.

it deals with the fight against eddie currents and insulation. rust is actually the best insulator for the individual plates of the transformer.

they have developed newer technology in windings since the old days so new iron doesnt need it. but back in the day guys used to purposely rust their OT's and it would actually make them more efficient.

i wouldnt let it bother you. you can take it off if you want - but its not going to hurt anything at all.

Damn didn't know that! Thanks for the info. I guess it won't hurt the resale value of the amp then.

Dude, you have a 5150 - albeit apparently for sale - therefore your opinion is invalid :lol: :LOL:







In all seriousness, I did not know that. I passed up a great deal on a Mark IV a few years ago because I was put off by a rusty transformer.
 
yup - its all true :rock:

i remember reading an article on it a long long time ago. there was a guy that used to sell rusted OT's too. sounds really stupid and odd as hell but rust is an amazing insulation for a transformer. i will try to do some research for you and pull up an article to show you :rock:
 
I think it would depend how old an amp we're talking, and where it's from.
 
find some specialized help to polish your transformers :D

This is interesting.

in theory of course. nowdays better technology exists for laminating the plates of the iron put together.

before hand, they used to let them rust in sections or blocks before assembling.

there was an old old old article about it with some mountain scene where a guy living in BFE had transformers rusted to hell for this reason - ready to be assembled. its been so many years back though i cant remember all of the exact details as to how - but the article i posted will proove the math/theory as to why.
