I suggest to use TOP3 outputs like SanKen 2SA1294/2SC3263.
For test use 150R/10W instead fuse in 220V AC line.

It will take lot of time for me to get SanKen 2SA1294/2SC3263, can I use two pair of MJ15024/MJ15025 as mounting holes are already on heat sink.

Sir Sonal,
If you are using MJ15024/MJ15025, there are 24 strands of wire chases in the box.
If the project is finished I want to hear about it from your review.

Good luck.

Yassud
