What To Do With Those 2SJ28's

Leave or lift?

The bracket holds 4 TO-3 transistors. At least one of them will be a VFET.

Yes Mr Pass thanks for lift it.
Four metal TO-3 that is yummy interesting.

One is Sony Vfet TO-3 and the other transistor is a top secret

Brackets due to arrive.

Thanks very interesting ! Do Mr Pass SE kit include Vfet + brackets and the other TO-3 transistors + jfet's ?
Please Patron preview information what no vfet semi's reference(s) is ?
Best regards from Greedy Boy

The kit I have in mind has 1 VFET and 3 Mosfets, all in TO-3 packages.

The other option is 2 VFETs and 2 Mosfets for either balanced or stereo,
but getting twice as many VFETs for it remains an issue.

I can't even imagine how big number is of T03 cans in Papa's Ark

Single - Ended Balanced version is perfect for Diyers who have few extra Vfet's in the drawers. Me included.
Look forward on both options and his specifications. Thanks Mr Pass for watt's news ! Kind regards

I have 12,000. That is why I ordered 3,000 brackets that hold 4 each.

As to VFETs, it's gotten pretty thin. I have about 400 of the Sony VFETs
allocated for the last project, which is 400 channels, plus a few for repair
and my own use.

SIT-1 transistors are also on their last production release. The SIT-3
is slated for 250 amplifiers. Again, I have rejects and a few allocated
for repair and R&D, but that's it.

After that, a few very large parts, 2SK77B and other Tokin 300W devices,
not enough for a production run.

And after that? Darkness?
