Smile BOZ preamp project

Hi all,
I'm going to build a Bride of Zen pre-amp but I have some difficulties finding some parts.
Can someone tell me the equivalent of IRF610 and TIP29GCE ?

Is IRF610 = IRF9610?

These IRF and TIP will be solded on the same side with other parts or on the other side?

I have finished the PCB as in the passdiy.com.

Thanks heap.

Cheers!

LikeDIY,

I thinks, The IRF610 is not equivalent with TIP29GCH.
And IRF610 = N channel Mosfet
IRF9610 = P channel Mosfet
You can buy the IRF610 and IRF9610 at MOUSER and DIGIKEY

Thanks Seene, but I didnt mean the IRF610 = TIP29, What i meant is "What are the equivalent to IRF610 and TIP29".

TIP29:

The operating voltage between C and E is about 25V and current is less than 0.5A. I however would apply my "don't worry be happy" factor 2. If so, any NPN TR rated at max. VCE of 50V and 1A or bigger will be okay.

IRF610:

Buy all IRF510/ IRF520/ IRF620/ IRF630 /IRF140 /IRF240/ IRFP250N . . .
And take experiment of sound differences from them . . .
Lot of fun . . . !!!
You will love diy, Likediy . . .

I that I should have said "min" . . .

On the PCB, i have seen there is a hole for the drain of the IRF, I'm a bit confused how we actually connect the drain pin and this hole, is this through a screw nut?

Put whatever . . . tight size into the hole . . .
As you know, as long as the drains are "electrically" connected with R104/204 . . . fine . . .
