KS1000.1 ARC Audio

[ANTONOV144]

Hi i got a KS1000.1 with no power suply transistor and no output transistor, so i'm trying to find the part numbers and see if i can make it work. I hope someone can give me a hand with this missing parts. Thanks in advance.

Perhaps ask the guys from arc audio... They always try to help...

A friend told me that this amp has the sanken A1294 and C3263 output transistor, but this are very hard to find and expensive too, i wonder if i can use another alternative like the
FJA4213
FJA4313
..............?

I have one here I'll look.

Not sure what revision you have but here's what the one here is.


Power Supply: 75344G board location M3,M4,M5,M6,M7,M8


Output Stage: A1294 board location Q5,Q6,Q7,Q8
Output Stage: C3263 board location Q36,Q37,Q38,Q39


This is for Arc Audio model KS1000.1 Revision 1.04 2007


Hope this helps!!!!

I think they have a good chance of working in that amp.

Hi i apreciate your help guys, i will try with what i can get for now and see what happen but i gonna need more help, i just noticed that there are 3 blown capacitor in the power suply too, C53, C117, C116 and there is no way to get the part numbers either.

Contact ARC Audio. They should help.

These are the values from the same amp I have here.


I will post markings from devices.


C53: 1N5K4 11 not sure about the 11 cant make the last 2 out.


C116: 393J 100v
C117: 393J 100v

Ok thank you very much, i'll try to find them.

 

[ANTONOV144]

i'm still with the same amp, now i need to find the power suply gate resistor couse they are blown also.

Post a photo of the board if you still need help with this.

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

ks1000.1

here is one pic of the board and one of the power suply gate resistor.

I don't have anything on that one. Contact Arc. They are generally helpful and if you ask they may even send you the diagram.
