apex b500 stereo Sprint Layout file
there is .lay file (open in Sprint Layout)
(i didn't know that file should be a zip file)

B500
greetings...
may i ask for Mono-Stereo-Parallel circuit option for 2 channel B500
thank you

Does any body have gerber files for apex b500 tef ? please post a link or send me. Thanks in advance.
i have used mjl3281/1302 pair(5pair) insted of 2sc5200.dc voltage is +-82v ..nice clean sound super bass..
i have built my Own pcb . schematic is b500 standard virsion all components same as schematic just change outputs... for more reliable in bass note i used mjl pair.cheak my dual 15 inch top result is awesome....crystal clear audio.Thanks mr.mile..
Hi,Mr mile...I have 2 questions 1)can b500 handle 60 0 60 v ac with 4 ohms load with 5 pair mjl3281/mjl1302.??
2)is their any replacements of driver or other components for this voltage??

hi , what is price of mjl ? and where to get in india ? i test with +-90 v dc b500 works good but heat more coming.
I bought them from mouser.in online store @RS--500/ pair.i also test with +-82v dc 2channel with 2nos dual 15inch top (500w rms each speaker)with full volume in whole day...With big heatsink and 4inch cooling fan..Result is aswame...Mainly bass note it's punchy.
Crest Audio used 7 pair 2SC5200/2SA1943 with +/-85V in FA1201/2401. The driver was one more pair 2SC5200/2SA1943. Triple darlington would better to use for such high power amplifier.

Thanks for answering sir.
7 pair 2SC5200/2SA1943 at 85v = 1A×7=7ampere.(2sc5200 at 85 v SOA 1A for music) But 5 pair mjl3281/1302 at 85=2A×5=10ampere.
So,i think 5 pair mjls are more powerful then 7 pair Toshiba ..Is it correct sir??
Can I replace my driver mje15032/33 to 2sc5200/1943 without charging anything??
the Toshiba 1943/5200 are rated @ 150W @ 25degrees C at up to ~44Vce, the ONsemi 3281/1302 are rated @ 200W @ 25degrees C at up to 4A @ 45Vce
To see this more clearly you really need to use a plot of temperature de-rated SOAR vs load power and the Toshiba shows much lower capability. This becomes especially significant at the higher voltages, above 55Vce
I use a very simple guide for determining the maximum reliable power output:
Pout = total output device Pmax / De-rating Factor.
For mosFETs DF = ~4, For BJTs DF 5 to 6,
ONsemi work with DF=5 and Toshiba work with DF=6
5 pair mjls =10*200=2000
Now 2000/5=400watts.
4pair Toshiba=8*150=1200
Now 1200/6=200watts.

that shows that 8pair of Toshiba roughly match 5pair of Onsemi.
In your previous post you compared 7pr to 5pr
Have you tried comparing current capability @ 100ms & 60Vce?
Worth having a good look at the two datasheets for the higher Vce SOA limits.
Rough work... 😀😀😀

Good Day Sir,
At what load are you referring to?
4R or 8R
can Amplifier classes has something to do with the power output?
especially when used to class H with 2 or 3 steps of voltages
thanks
