Kirkwood Rough, if you have not met, runs Upstairs Amps. Â He is an electronic magician. Â He can fix anything you can break.
Rather than replace a vintage amp transformer he was able to perform open insulator surgery to find and repair the lead that some how came off or burnt off the output lead.
It is hard to tell but the coil wire is very very small and this is a very delicate operation. Â Good news is the vintage amp now remains original.
