b5oo second channel on the go...
apex...,,
sir..,,
tonight, i had a sigh of relief...i finally made my second channel work...😀😀😀😀😀🙂🙂🙂🙂
i replaced all MJE340, MJE 350 and replaced zeber diode 15v...
but there is one thing i am concern...when amp is powered on and speakers tapped to output, dc voltage occure at output...but powering amp without the speakers, amp work normally...
what could be the prob???...😕😕😕😕
tnx...
regards...

What size dc offset are you getting ?
What size dc offset are you getting ?
i got 15v of dc from the output...🙁
hi apexaudio
greetings can b 500 be bridged for 8 ohms load more output transistors will be added to make amp safe is it possible
thanking you

B500 can be bridged, for 8R you don't need added more outputs, it's safe with 4 pairs of outputs per channel,hi apexaudio

it's time to burn
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...

Transformer
Hi i want to make a transformer for your amp. Any ideas on stripping a microwave oven transformer. I mean the turns ratio, i dont want to tamper with the primary.how many turns 4 the secondary if i want to make a 50-0-50 supply. Thanks guys!

the picture on your amp? look like you bridged it or you just add transistor?

i simply added power trannies on it...for safety operations...since my heatsinks are very small and thin...🙂🙂🙂
