This is really bad news.
BTW, among the list of soapboxes, which ones are supposed to be better sounding (so i'll stock a few pairs)?

All MT200 are good... they come in single chip, LAPT (Multi Emitter) & Darlington... Ft ranges from 20-70mhz with the high powered Darlington at the 70mhz (2SD2561)

Here’s a list - taken only in November

Hi thimios,

yes, you are right, I should have fired up my Tek 576 curve tracer, but I was lazy that day.

Have tons of 2SA2223AY and 2SC6145AY on stock. No need for the big MT200 case.
But of course it's very sad when another good old tranny goes EOL...

BR, Toni

KCT... you must be making some good amplifiers... I am now trying to get the coin to buy 100 of each device... every discrete amp I have is running MT200 devices on output.

And a month ago developed schematics to replicate Darlington new class A power amp chips with more aplomb, to find this discontinuation is a right wench.

Think I better tell Gryphon in Denmark to stack up on there so decent power amps are still available

I had to.... no one else will be making anything decent that’s available anyway.... though some of you on here could certainly fill the void that will be
