if you have them already on hand, yes, but if you are going to buy, then the MJE's are better to use...there are now local on-line shops, like deeco and newport electronics, even alexan or e-gizmo can be source of parts, apart from element 14 and rs philippines...
All To264, 247, 220 have the same pin out.
Only To126 is reversed.
Except Lateral mosFETs. They have the Source in the middle, whereas the Vertical mosFETs and BJTs have the Drain/Collector as the middle pin.

can i power this amplifier sir with 87 volts dc..?? how many output like 2sa1943 and 2sc5200 do i need
how many pairs are you using? the 2sc5200 is not that robust above rails of +-55volts....
sir i dont understand about the rail but all i know is my transforemer is 65-0-65 ac.. is this ok for this amplifier sir..?? how many output or 2sa and 2sc i need...
sir ajt i'm using the original pairs of output 4 2sc and 4 2sa.. but i didnt try yet to supply the 85 volts dc coz i want to ask first before i try the transfoermer
a 65Vac transformer will five you about 90Vdc to 95Vdc
a 65-0-65Vac transformer will give about +-90Vdc to +-95Vdc (190Vdc total across the supply rails).
ClassAB will blow up your 1943/5200 transistors.
Try ClassG, or ClassH, that may allow your transistors to survive.

hi guy can i asked, i want to build apex psu 7 for my b500, can i replace bc517 and bc550 t0 2n5551?? thanks 
best to follow designer's comments,
raising the rails while giving you more power,
does not necessarily give you more spl.
using lower rails makes your output trannies
live a little longer than with high rails...
Need Gerbers files for each PCB's
PDF versions of the PCB's are fine for making the PCB's yourselves at home,
but I would like to send the PCB's to a vendor. I have made PCB's myself but
I do not like the mess and nasty chemicals.
Unless someone knows how to change PDF PCB images into Gerbers or
something that software, like Eagle, etc., can understand, then I need
Gerbers files for each PCB. Another option is Group Buys for each PCB's.
Let me know what possible. Take care.😕

can i load this amplifier with 3 speakers sir 8 ohms each speaker..?? my supply is 54 0 54 ac 20 ampers
The output from a 54-0-54Vac transformer will be somewhere around 600W to 700W into 2.7ohms.
Will the output devices and drivers survive your operations?

i have 3 speakers sir at 1000 watts each,, can this amplifier handle this..?? the amplifier wont be damage..//??
