Use ML3 preamp http://www.diyaudio.com/forums/analog-line-level/167363-mic-line-eq-preamps.html

Mr. Mile,

Is this regulator can handle 83VAC input to regulate +/-90VDC output for B500? if not what are the changes needed?

Regards,

Yes it can be use for single channel B500 but you must use 10000uF/120V instead 100V and transistors MJE15030/15031 instead BD241C/242C,

You can simple increase output on your preamp, post preamp schematic and I will help you.

If one cannot remember
n = nano = 10^-9
u = micro = 10^-6 or more correctly µ (Greek mu)
m = milli = 10^-3
k = kilo = 10^3
M = Mega = 10^6
G = Giga = 10^9
Then print out a copy and paste it onto the edge of your keyboard.] 😎


THANKS FOR SHARING IT.

Stereo Speaker Protect

Mr. Mile,
I hope this is correct I slightly revise so I can use other kind of speaker connector for my stereo AX-14.

sir apex,
do you have top pcb layout without parts of ax14 and PSU with short circuit protect? i will use it for tone transfer.

 

[joeyt]

sir apex,
i have found the top view pcb layout on page 104. thanks

An externally hosted image should be here but it was not working when we last tested it.

Rakesh,
are your 6 channels of speakers right next to each other?
Then why put your 6 channels of amplification right next to each other?
To save money, or to give better performance when driving the speakers?

Why is it wrong? Heating maybe,or some larger troubles? It would be nice if this 2x3 chanel amp would be for tri-amp solution...
