There have been some posts lately about cascaded current source. With reference to JimL's srx schematic and the srx layout made by Kevin - I made a couple of small boards, surface mounted dn2540 along with some resistors and replaced the two 10m90s resistors.

Looks very compact and elegant indeed. Nice work as always.

Would cascaded CCS - be of any benefit in modified T2?

How about HN4C51J as replacement for 2sc3381? It's a Toshiba dual NPN common base in sot-25.

Just curious. Did Stax use c3381 in T2 servo.

Beautiful. Like that top cover.

Thanks for info, that's good to know.

Left channel 510R: 10.178V, 6k2: 11.428V Right channel 510R: 10,147V, 6k2: 11.395V

Thanks for advise.

The designer of Stax SRM-T2 he knew what he was doing.
