Babelfish M25, SissySIT - general building tips and tricks
few things - don't waste your time with WCF; I made it as option , but consensus by now is that is too much of good thing ...... interesting for Babelfish M25 , simply because of inherently much lower THD than SissySIT , so adding some sugar can be good in some circumstances

while with SissySIT , in most cases it is too much

regarding F4 - as I'm always saying - there is no comparison between amps really ...... but comparison of some other amp vs. preamp driving a F4 ...... simply because F4 is always just forwarding preamp's character , nothing more

and yes - that NP of yours ......... my Pa is eating him for breakfast , every day

NP is fun , as I heard , but Pa is much funnier



edit: luckily we had few more eyes and brains , to help with your adventure ; mine would suffice eventually , but it was faster with help of Greedy Boyz

and ....... don't waste your time with serious listening ...... just enjoy ; I know that you must (and you will ) realize the same , but now you made one of the best small amps money can buy ..... either commercially done or as DIY

As always, thanks for the input.

I feel really privileged to have mono-block F4s & SissySITS both just hanging out ready to make beautiful music. Plenty of frustration in the build process, but also lots of enjoyment and learning. And I don't need a large amp, so I'll just consider that I have two of the best available...

Hi, finally some time to make an attempt to get the sissysit up.
Pcb’s are done, cinemag HQ trafo
Will re-use my two identical M2 amps as dual channel mounted monoblocks, M2 and sissysit per chassis. I shall power one channel per chassis.

Sissy question...
I have 4 Harris p9240 unused; in the M2 it was advised to use them, got them from Teabag, but I used Toshiba’s, so 4 left over, could use 2 of them.
Would they improve the amp, and if so; need to be measured for Vgs?

o yeah , Harris welcomed

no need for any measurements ...... at least that was my experience with P Harris - they were all well more than 4V of Ugs , for I/V area of interest
