Hi,
I nicked off some of the gold foil on the outside of the power
transformer ( Weber t025130 -- for a 18w TMB) . The foil
is about one inch wide and runs down the middle of the case.
What exactly is this gold foil do ? and have I damaged this
device ?
Foil tape on a power xformer ? Nicking bad ?

Re: Foil tape on a power xformer ? Nicking bad ?
Its an added shield that surrounds the entire coil, not hi-mu but sort of. The tranny will still work fine, but you may have reduced the overall sheilding of stray 'electons' or magnetic 'pulses'. Just find something similar in size - copper foil is best - and carefully patch the new piece on with a bead of solder.
If you think you need to have it, then repair it. Either way. the transformer will work as intended. If your build is correct, you will do more to have a quiet amp than having this strip intact and building things incorrectly.
Does this help?
And all of this being said, don't buy your iron based on price alone. Weber is an amazing source of many things that are very good, and the price on those things will reflect that. He sells Hayboer and MM trannys all day for a fair price, for example. Remember that the amp you are building represents a fair amount of your time and effort. Invest more in yourself, I say, and do that by buying at least something that doesn't leave you wondering if what you end up with - should it sound like crap - couldn't sound better if you'd used better components.
Really, that's the benifit of hanging out at a place like this. Ask people what's working and what's not. OK, trying to be helpful.

Most people stall out when fixing a mistake that they've made. Why?
