This listing is for one matched set of 4 Yamaha VFETs: two each of 2SJ26A and 2SK76A. I have all 8 VFETs, so if you’re interested in more than one pair, message me, I can give a break on the pricing. I’ve tested the VFETs according to the instructions shown in the picture (see above), they all test good. I removed one at a time, to ensure the matched pairs stayed together. If you’re interested in any parts, just send me a message.
