No I really mean 489, the new part that they were giving samples at Burning Amp. The distortion on the 389 was promising, and for power amp superlow noise is not 1st priority.
(edit: cant find correct part number)

the 2sk389 & lsk389 are 7 lead devices.
They don't fit the PCB by Roender, nor Rudi's !

Yes, the thick line matches the "bar" in the diode and LED symbols and also matches the "flat", if there, of the LED.
My 3mm LEDs don't have a flat, nor do my rectangular LEDs have an identifying/orienting flat.

I can make rectangular LEDs from 3mm round and 5mm round, to enable thermal coupling in the three (3) locations where Roender designed in the tempco.

It comes usable when you put them onto an adaptor PCB. I did an adaptor PCB for the BF862s but not yet tested.

John, it is nice to watch your progress.
Do it slowly and carefully.

Best regards - Rudi_Ratlos

P.S. The missing emitter resistors are on their way to you!
