Need amp for my PSU and out put devices

opor · 8th November 2005, 04:02 PM

Hello,

I am loooking for good quality PA amplifier. I have good switching power supply +/-70VDC (with input 220VAC) 1.4KVA and many Toshiba transistors, 2SC5200/2SA1943.

Thank you.

There are some great digital kits out there. . .PSU + Kit amp = happy
days.

As for the output devices. . . maybe ebay to supply the $$ for the kits.

Let us know how it works out.

Hi

It looks at the last circuit posted by fjromero
I am sure that he can be suited for the bjts Toshiba.
Pcb 300 W

I also think that the driverses can be replaced with the
MJE15033 & MJE15032 + 2SC3788 & 2SA1478

bye

at the first look :

MJ15003 = 140V 20A 250W hFE 25..150
TIP41C = 100V 6A 65W hFE 15..75
2SD669 = 120V 1.5A 20W hFE 60..320

2SC5200 = 230V 15A 150W hFE 55..160
MJE15032 = 250V 8A 50W hFE 100
2SC3788 = 200V 0.1A 5W hFE 40..320

with +/- 70Vs on 4Ohms is 600W
It would be better perhaps to put 6 couples of SC/SA

bye
