I bought a pair of Twisted Pair amp modules to go with the kookaburra, but they started to behave strangely when everything was hooked up. One day I should revisit all this and try to get something working again. To replace my self-built amps I simply bought a rack-mount studio amp to power my office speakers (a pair of B&W 600-series bookshelfs) - it sounds pretty good except for the fan powering the amp. ;) I still don’t know which of the parts was behind the 4875 explosion.

If the amp "modules" went kaput along with the power supply boards would you be interested in acquiring some new ones? If so, send me an email.

I have a sneaking suspicion that the explosion was localized to one of my two regulator boards, and the two amp boards were left unscathed. Because the regulator failed, though, one of the sides of the transformer was probably fed directly into the two amps' +V lines as 22VAC. I'll need some time to verify that first - hopefully over the weekend. Maybe I'll need to take you up on that offer if things don't work out otherwise... :) Thanks for the offer, Sheldon!

I've got a bunch of parts that may get your gainclone working again. Let me know if you need anything mail up north to you, it is a lot easier to drop a couple parts in an envelope than to put an order in to digikey and pay for shipping and wait. Are you power supplies still OK? The gainclone is so simple that there isn't a whole lot that can go wrong that isn't immediately obvious.
