hi diyers'
may i ask any idea on my b500 it works well but.
the turn on ploop strikes +/-30VDC
so i have used the h900 protect stereo with tip31 thermal diodes.
there is still about +/-4.5VDC which i think not good for the speakers

NSL32 can be replaced with 47k resistor and LED for 'clip' indicate, if you don't want use limiter,
MJE340/MJE350 need some small heatsink.
hi folks!
I'd like a advice from you all.
I want a good quality HI-FI performance amplifier and will have a power like this B500 !! I like the power of this B500 but need more HI-FI performance !!
Any circuit please !!!
A new design of b500 may be.
thank you all !!

I want to change predriver to mje15032/33 pair driver TTC5200/1943 pair and 5 pair mjl3281/1302 as outputs...can anyone tell me mje340/350 are equipment to mje15032/33 pair ? because I saw for tef version there all mje15032/33 instead of mje340/350.
I have a question.can i add one extra pair i.e total 5 pair mjl3281/1302for standard version of apex b500 without changing any component?And what will be optimal bias current for mjl3281/1302 pair at 75v dc ?
hi to all may i ask if i can use my 60-0-60AC trafo for B500 orig design 8 outputs using 1943/5200 or shall i use MJL/MJW for this voltage?
thanks

...or MJL/MJW/NJW 21195/96, which show about the same specs, but are (why?) somewhat cheaper than their 93/94 counterparts.
Btw, any objections against faster devices here, such as MJL4281A/4302A?
Best regards!
thank you so much for the reply...
especially to Mr. Mile...
i am sorry for asking too much, it is my avidity to these things constraining me to solicit advice, learning electronics through ethernet is difficult but because of the support of this forum all my apex designs are working great compared to available hi fi or mid PA in the area. (b500, sr200, ax14, ax20) next in mind is the Hclass, but i have to go to school for now soon i'll do it after parts are complete.
best regards...
