Thanks Apex...I see it...so I think "dot/catode" on body NSL 32 must be same with "dot" code on PCB B500/H900. Catode NSL-32 connected with R 6K8/2W and negatif dioda zener 15V. Its OK?

Pozdrav.

Hi Apex. I have 2 questions for you:
1.What voltage do you recommend me if there are two 2SC5200 and two 2SA1943 on pcb?
2.What power will I get with +/-56V?
Thanks
Regards

1,2 - two pairs 2SA/2SC with +/-56V you will get about 120W/8R (resonable THD)

the 1943/5200 have a very poor SOAR at higher voltages.

Using +-56Vdc should give good 8ohm performance, but these devices can only manage 40 to 45degree phase angle when kept cool.

However, using +-50Vdc, an 8ohm load of 60degree phase angle can be driven to full power of ~110W. You still have to keep them cool to stay within the de-rated 100ms SOAR
