More from the illustrations page of my KISS amp:

and description of how to use the information at Jute on Amps:

Here is an interesting project for those here looking to DIY a Stax amp. I built this one a few years ago, but was losing all the gain across the string of gas tubes. Kevin said this didnt happen with his, so it could have been my tubes. I never bothered to try different ones. It's a neat project, the gas tubes dance to the bass.



Interesting link! Do you know if KG has ever designed tube rectified bipolar supplies for any of his amplifiers?

ok,
so the headphones can be plugged in every amp.
buying also an amp in japan, i need a converter



The headphones can be used with any Stax amp or adapter (except the SRD-4 since it was for electret use only) ever made. You can pick up a used amp and buy new phones or the other way around. The new amps lack the older bias though so they can't be used with very old phones.

The amps use the same transformer whether they are the A or II model but Stax won't give out how to configure them for 120v/230v use. It can be done though but a good external transformer isn't the end of the world.
