for some reason i was quite confident this one would work,
looking back im not sure why:)
ive had some pass f-5 pcb boards lying around this long time waiting to be put to work
using a variation of the power technology used the group buy amp i used these premade pcbs
http://passclone.blogspot.ie/p/blog-page.html to prove my theory before starting from scratch
(these are good quality and good value really would recommended for a standard implementation )
once the pass clones were installed it was obvious that
A: it worked
B:the power supply was able to keep up with the bias discharge just about :)
C: it sounded good enough to pursue further investigation
D: and of course most importantly.... IT DIDN'T EXPLODE!..
this followed by using blank f5 boards to try my lunacy on
direct connection to the almighty power of the lifepo4 battery pack
precision resistors in the feedback loop
jfet buffer pre entry to amplification
After some soldering, head scratching and the magic smoke rising
i had the first working prototype
and boy can she sing
then on to fryderyk for the first class pcb design
only one issue with it is the amount of heat it generates as a stereo unit
im fairly sure if i put a lid on it that it would hinder the cooling enough that you could call it a stove!!
this is because there is 20 regulated supplies in it all working at moderate levels
plus the heat dissipated through the output mosfets
Mono is the only way this bird can fly (well safely at least without concern or fear)
which i plan to do for myself in time
