Joke or truth?
You speedy finder on the web 😉
How many well documented educative DIY publications on line, we find with Tokin SIT's and Ge?
I mean in class A, practically none. It's a voyage on audio "Forbidden Planet".
Luckily from time to time exceptions are the "messages in the cabernet bottle" from the Wiz of Sea Ranch

I recently watched the video of Nelson's stash of SITs, etc.
It will be very interesting to see what Nelson creates with the Tokin SITs and the Germanium power transistors.
