[lelut]

hi Apex..

i want to continue this PCB project,
what the additional circuit to complete perfect power amplifier (PA),
for illustration:

input--->APEX550--->output

what kind of input and output circuit for best PA?
can give me the circuit schematics,

thanks

With only 3 wire for connect this VU meter can be add to amplifier, and you have 4 LED display per channel.

I find this paper (over 20 years old), single pair 2N3773 without zobel but with VI limiter.

You can use 2SC5200 instead 2N3773, this amp use only NPN outputs.

sorry sir my bad thx for the reply and btw sir if i used 10 pair of output using 47.5-0-47.5 volts how much overall output wattage and sir all of the caps in electrolytic value are all in 80volts or 100volts espicialy for pf and nf thx..

@apex i've done with the PSU my only question sir is in the PCB 80 volts or i'll go for 100volts thx....

Use 80V caps in PSU. 100uF/25V, 2,2uF/50V and 470pF/50V in amp input, all others 470pF/250V and 100nF/250V.
