I found this: http://www.kk-pcb.com/hiraga.html Maybe I'll build it just for the hell of it. But what I would like the most is some kind of good (and cheap) circuit to reverse the polarity for a "balanced output" version of JISBOS. With 6 db increased gain this would be a real killer.

Did I say this amp sounds good

, can't stop listening.

N.V, Where did you get the schematic of the actual amp you built?
Would you print it if it is not available on one of these forums (fora?)?
Unless that is not what the designer wants.

I just made it battery powered/portable. And because of that I had to use some kind of ground channel. It's just two JISBOS with a 10 kOhm pot, a TLE2426 as railsplitter/virtual ground (or in my case two resistors since I fried the TLE) and another JISBOS as active ground. I can draw it sometime, not today.

Look at this (at the bottom of the page) http://www.tcaas.btinternet.co.uk/jlhphones.htm , even simpler. This is from the 70's! Progress (read opamp based amps) is sometimes regress

.

TNX, I found it on the Headwize site--the final version
