Help needed with old Sanyo STK chip amp please

[georgehifi]

Hey guys, i`ve just got hold of a pair of rare Sony Electrosatic hybrid active speaker with motional feedback on the mid/bass unit, can you guys help out with info upgrading the the old STK401-100b chip that`s used in each speaker, they use half for the mid/bass 60watt and the other half 60watts for the ESL pannel, it also has 2500v power supply for the eht.
From what i`ve found on the net the stk401-100 is an old amp and i`m hoping that there is a better sounding stk that could be a direct drop in replacement. ( here`s wishing) Sorry guys i know nothing about chip amps.
Im normaly into tubes, but also an esl nut formost, and i just love these little Sonys.

Cheers George

Thanks Moamps but i`ve already got the data sheet, what i really need to know, is is there a drop in replacement that anyone has subed for the stk401-100 that is a better sounding amp module.
As the stk401-100 is a little rough sounding.

G'day George

When are you coming to visit me, just head down the M5, via the Eastern Distributor and after peak hour traffic it's a breeze. Much fat to chew over plus equipment here to sample, even a decent bottle of red or white, got 'high altitude' Canberra wines from a trip down there. Good stuff!

As for the STK, not even in the same league, period. It may not be a drop-in replacement but worth the extra effort and equipment surgery required to make them fit. Jaycar sells LM3875 for A$14.95 and Electus under A$10 ($100 min order). If +/- supply is no higher than 42V (absolute max), I'd go for it.

Want to sample it in a good system and excellent room with an astonishing source (you haven't heard it)... you know where to come.

And oh... these little critters love a tube frontend.
