nope...got them replaced...as what sir apex advised,...nsl 32 can be replaced with regular LED and LDR,...47k resistor may also do the job in place of LDR...LED serves as clip indicator...i placed it in front of the amp so i can see if amp clips...then i may lower down the volume...
you can also place LED and LDR in a black tube facing each other...
this serves as an improvised NSL32...
tnx to sir apex advices...everything worked fine...
i simply added power trannies on it...for safety operations...since my heatsinks are very small and thin...
esbiboi what trannies you used on output mjl21193 or 2sc5200 where did you buy the parts at cebu? coz im planning to make?
i used 2sc5200/2sa1943...are you living in cebu too???...i bought them at advance electronic supply...
power out bridge in 4 ohms
Hi Apex,
What's the output power of your H900 in bridge config at 4 ohms speaker?
Thanks,
Joel

Transformer
yo thats a big transformer. Where did you get it and what are the specs?
hi everyone!!!...
today i've finished b500 and have mounted in the chasis...
i've tested it today...amp sounded reall good...very good for mids...
very crystal clear audio...very nice highs too...
one should make this amp...
tnx a lot to sir apex for sharing this very good sounding amp with us...
thank you sir...
this amp deserves a drink...

my friend made that for me...he made it in just a day by hand...
EI core with 0v 220v 240v primary and 50 0 50 secondary @ 20amperes...
Transformer
thats nice. Is it possible to make a similar transformer from a microwave oven transformer?. I have rewound one and its giving 35-0-35 ac. At no load its not heating at all. Is it suitable for the B500?
Thanks in advance

Yes, but voltage to low for B500, better use for this amp http://www.diyaudio.com/forums/solid-state/164093-100w-ultimate-fidelity-amplifier-28.html or this http://www.diyaudio.com/forums/solid-state/162081-dc-servo-mosfet-amplifier-8.html

Transformer
if i use it with the b500 how much power can i get considering that after rectifying its gonna be something like 45-0-45. I want to use this transformer till i get a good one

Bridge B500
How about this B500?
Do you recommend this to be used with 4 ohms load in Bridge?
Pout = ?
Thanks!

I not recommend any amp to be used with 4 ohms load in bridge, but many people do that without problem. If you use 1000VA transformer for stereo B500, like QSC in RMX1450 or CROWN in XLS602, you can used 4 ohms load in bridge.

apex, sir...
sir im very sorry for this silly question...
how do i translate 50v 0 50v 1000va trafo into amperes???...
i think i've read it somewhere in the thread but i just forgot where...
salamat po,

i really hate math...
i think it's p/v???... 1000/50+50= 10 amps ???...
correct me sir if im wrong...

This math is correct, and you must use it in electronic, it's basic math not high school,i really hate math...

He hate math, but he like to soldering
it's not that i really hate math very much...i just dont like counting NUMBERS...
but for sure, i love to solder...
