HI RHODRICH
greetings 90 0 90 ac voltage to much 2SC5200 2SA19A43 DC VOLTAGE R AILS NOT MORE THAN 70 VOLTS OR TRANSISTORS WILL
HEAT MAKING AMPLIFIER UNRELIABLE
YOUR E MAIL ADDRESS
THANKING YOU
MICHELLE

sir
i'd also like to have what you wanted to send to rhodrich...for i am also planning to build this amp and feed it with 80 0 80 trafo...
any advice from all of us here is highly appreciated...

can i use mje15032 instead 2sc4793?
what are the other replacement

 

[michelle]

hi engel
greetings 2sc4793 no need for mica insulator cheap easy to get
thanking you
michelle

 

[erhan739]

thanks michelle for your posting.
it's true. no need for bias to this transistor. it is expensive the others. no need spend cashs. but you have, you can use it but before compare data sheets.
Thanks for interesets...

hello erhan can i use TLO71 instead of ne5534?

 

[irvynejay]

any replacement of uf5408 diode?

 

[michelle]

hi irvynejay
greetings
1 any diode IN4007 CAN BE USED IN5399 CAN ALSO BE USED apex audio uses IN4007 IN SAME POSTION
2 try ic NE5534 AN FOR best result just check INVERTING NON INVERTING OUTPUT POSITIVE SUPPLY NAEGATIVE SUPPLY PINS FROM DATA
OF ICS
THANKING YOU
MICHELLE

michelle,
waiting for your mail

 

[erhan739]

hello erhan can i use TLO71 instead of ne5534?

hello, you can't use TL071. because tl071 is dual, ne5534 is single op-amp. if you want use it you shuld check datasheet on www.datasheetcatalog.com
thanks.

 

[erhan739]

any replacement of uf5408 diode?

you can use any ULTRA FAST DİODE with replacement.

 

[irvynejay]

michelle,erhan
Thanx for the advice ill post result when im done making this circuit

 

[irvynejay]

Hello erhan can you pls help for the wiring diagram between output board and the driver board pls

ehran,
tlo71 is not dual,it is only single but j-fet input
please check

I see ı was messed up 72 and 71 sorry, But the circuit best works with 5534. and replace mje 340 350's base capacitor with 10uF 250v if you want deep bass sound.

Hello erhan can you pls clarify witch of the capacitor should i change 2 100n capacitor change to 10/250v?on both pre drivers and there polarities?

 

[erhan739]

Okay; ı'm uploading an image. you can see.

[irvynejay]

thanx erhan your circuit is almost dome ill put some picture when its done

 

[irvynejay]

erhan circuit almost done

one channel ready for wiring

 

[erhan739]

woow irvynejay, circuit is looking perfect you shuld say the results from testing!

your amp is awesome good bass,,just one question what is the safe voltage or trapo Ac to be used

can i use 60 0 60 ac 25ampere trapo or 70 0 70 ac 25 ampere trapo
pls i need your advice
