I have a Goldmund Mimesis 9 amp in need of repair. I brought it to a local guy that tells me one of the transistors needs to be replaced. But they are matched pairs of Hitachi k149 and j49 transistors. These are not made anymore. Does anybody know where I could get replacements in matched pairs? I need three of each. Goldmund is of little help. What do you want for 15 grand I suppose.

Thanks
Chris

I would replace both channels with matched pairs. If you can't find matched pairs, you may have to buy a small lot and measure them yourself for matching purposes.
