I've been having Paul Birkeland, designer from Bottlehead tube kits, do all my work for me. He's worked on a SET 300B amp, on which he adjusted the filament voltage to better match my EML XLS 300B tubes, and also replaced a couple of bad caps. He said pay me $20. I gave him $120.
He then pretty much rebuilt a Chinese SET 845 boat anchor for me, replace all the caps, of which there were a couple dozen (at least), and did other things to improve reliability. Both amps have been working beautifully, and sound incredible despite their humble origins. That job cost $500, and was worth every penny.
I can't recommend Paul enough. He lives in nearby Renton.
Regards,
Dan
