eesbiboi,
MUR1620,(hard ti find)but.......
any 100v 8a will do,(back to back diode),
I use D5LC0U,from scrap
and.....,
BF422/423,... ecb ....(hard to find)....but
MPSA92/93,.... ebc .... will do (different pin out)
engel...
i see...this diode is a bit hard to look for...
i might also find it hard to look for substitute little trannies...
anyway...
thanks for the info...
i'd first have to build another aB amp before i proceed building step drive...
regards...
ees
Hello Apex,How reliable is the short-circuit protection, such as the transistors do not die when the output is shorted?
Short-circuit protect is never 100% reliable on high power amplifiers, only short-circuit protect from this thread: http://www.diyaudio.com/forums/solid-state/162081-dc-servo-mosfet-amplifier-3.html can be 100%reliable.
Regards
2 Channel B500 with protect connected

Thank's for the pictures, thermal diode BD241C(TIP31C) must be on main heatsink.

yes when i finally mounted it on the chassis i will put it on the heat sink. when B500 fully done i DIY H750 or H900 soon..i am very thankful to you apexaudio
ALL Chassis And Speaker boxes will be named by Author APEXAUDIO: for Credits
Do you planing to build some of my speakers boxes?
Bass from B500 have very good definition, and I like it, but you need 'CREST' style like VERTEX for 'real hard bass' or somethin simplier like this:

sir apex do you have simplier to build high power amp.for sub woofer used

This amp is good for sub, and in bridge mode (post #206) it's very powerful
