irf 9610s and 610s and ztx parts search

[Stefanoo]

Hello to everybody.

I'm building my P1.7 preamplifier.
I'.ve just finished to design the PCB and now i need to put everything together and test the system and do the necessary refinements.

I would need to know how to get those parts MATCHED...or...at least get some...and then i will match them by myself.
Is there anybody on the forum that could sell me a stock of this "s" version that, apparentaly,from the research that i have made here, they seem to be the most suitable for this project?!
(anyway any suggestion on this point over better parts are welcome)

In case nobody has the parts, where can i get those mosfet?
Digikay has the IRF but not the s version.

Consider that i'm from italy....who's a good dealer?

Where can i buy...let's say....20 for each one?
same thing for the BJT ztx...i would like to match them as well.

I hope somebody would supply me with those parts.


Best,
Stefano.

i noticed just now that i can buy the s version on digikay, but the problem is that it fixes the minimum quantity at about 400unit (a little too much for me )

Could anybody help me to get the 9610s and 610s and the ztx550 and 450?


Thanks a lot.

Best,
Stefano.

you really don't need ztx-es; use whatever from BC family-I'm sure that you can find them in any tobacco store on next corner....... BC550C/560C are more than adequate

regarding IRF......what's exactly meaning of "s" ?

I'm pretty sure that Papa is ROTFLMAO or whatever zillionth time .......hehe - I remember also asking him in PM about adequate mosfets for A30.........

I think the S is just plural
one IRF610
two IRF610s

Ciao Stefanoo

I found ztx´s from Farnell, P/N 358-137/358-230 (minimum order of 5 I think) and matched IRFs from Rick Tepstra http://www.rt-audio.nl/ or Marcel, "tarasque" on this forum.

Cheers

If you want to buy both, the best way I found is:

http://www.rs-components.it

If you order minimum 25 pcs the costs are (each):
IRF9610: 2,13€
IRF610: 1,15€ (not IR 0,82€)

You can mach by yourself how NP teach:
