wow,
good to see that Bill will still be involved,
he is fun and a delight to talk to on the phone, treats you like his best friend, will answer all your questions with no BS, and spends as much time as it takes,
Jensen only sells one tube output transformer, the JT-10K61-1M
it is so good that no other models are needed in the product line,
layers at the beginning and end all have different turns counts, this is to make it run as flat as possible, you can not design a transformer like this with calculator or a computer, it has to be done experimentally, so tons of time spent figuring out how many turns per layer, never seen another transformer with so much turns tweaking as the JT-10K61-1M, and i do not know where they get the lams but they are incredible, more Henries per turn than anything out there except maybe Tamura,
try one today!
(never know what happens when a new guy takes over)
check the crazy good specs>
