About the 4 pair version I got from buzz. Power a plenty.... I have been using the boards with a pair of 24 volt 400 va transformers running about .55 amp per device. I needed fans on the heatsinks too keep things cool. My speakers are fairly efficient, but the set seems to sound better with a preamp.
Comparing it to a stock f5 .. sounds similar, but where the f5 seemed to run out of steam this one doesn't.
Compared to my Moskido running same transformers with 2 pair per of buz901/906 per channel this amp sounds a bit dull. Snare drum, slapped bass, this sort of thing lacks the realism/impact that the moskido has. I have been running the f5 with the aikido push pull front end as a pre amp so I believe the comparison is valid.
I know my comparisons are amateur...but that's all I got...
Evan

Thanks for sharing Evan. I wouldn't expect a huge performance increase in going to 1A. You can fiddle with P3 if you want. Just watch the output offset and make sure you readjust. I believe the J74 has higher transconductance, so to reduce distortion, you want to degenerate it more, to bring it into line with sk170. I believe that is turning it towards the bottom or counterclockwise, but dont quote me. Been too llong since i fiddled with it and too many other things swirling in my noggin.

This is why I am sticking with f5tv2, what horns are you going to be using.

Altec 416 paired with Iwata 290, with ALtec 288. If i dont like that I will go for jbl2235 or TD15m. I am thinking i will like it based on what I know at this point, but you never know. Alternative to 288 will be Radian 745 because they are supposeddly making a truextent diaphragm for it. May try the HornsPL JMLC350 as well. It, like all things, will move and change as needed. I might love the ALtec setup and stop there

To build the power supply for a monobloc F5T V2, is it the best way to do it?

Hi Everyone,

Can someone tell me if this diagram is correct or not?
My big question is how does the output sum between the N channel and P channel boards?

What is "LINK"? Looks like Ground.

All other ground best be sent to the power supply as a star ground.

Modify this diagram or please draw up another diagram.
Made in Microsoft Paint and the file is a jpeg.

Thanks,

Vince
