Layout and pcb.
Ver. wit 6 pair of outputs require A3 format of printwork.
No changes from original, only 1 or 2 pairs of tr. more.
with 5 or 6 pair output, u need tef driver stage,
without tef driver stage maximum 4 pair outputs for safety.

I'm not using toshiba's, have done some testing with diferent outputs with much less beta-drop on another amps and endup werry well. Gonna make one of this 2 ver for fun anyway, not for real PA.
Hello Nazirdigi,
How's the outcome of this project? is it successful?
what's the different compare to 4 pair?
Regards,
This statement is true if you add at the end "with the same psu voltage" 😉
This one might be if you specife type of outputs 🙂
Regards.

That gives advantages if you use six pairs.
1.-power increases.
2.-votaje to the PLS is the same.
3. - We need to increase the font ampreraje.
4.-As to amending bias amperage.
5.-If aumeto the eight or more pairs to get some advantage.
Postscript: Veljko, thank you very much for uploading all this information.
best regards, Sergio.
B500 tef,
thanks for Mr Mile for B500
For example this is the eight pairs.
A loose question, or who has performed the ten pairs.😱😱😱
This is driver for b500 tef and will upgrading in h900tef vertions...

I do, i played with some transistors and use a chip amp so this is my first homemade amp
Just for fun!!! My APEX B500 in Vertical & Horizontal
My new APEX B500 in Horizontal position (tested and working) with APEX protect using NE555 IC in progress.
Many thanks to APEX....
