Looks Great Oliver

But i dont think it will be long before it really becomes hotrodded

At the moment im running my DCB1 at 350ma...and it sounds so much better.

Cant wait to hear your impressions.

The Heatsinks are from Fischer Electronic typ SK68.

I use the 75mm version and shorted it to 60mm, so they fit perfect to the mosfets.

I wired up my Hypno this afternoon; single input and the output through two 4uf wondercaps as neither my Aleph 5 or F5 has an input cap. The p/s voltageswere 9.6 & -9.58v with dc offsets less than a mv[as posted previously].When I checked the dc offset after the caps I had readings of 26mv and 100mv which slowly dropped towards zero if I held the probes there.
Can anyone explain this to me please and is it a problem?
Thanks in advance.
Marra

Use 1Meg resistors from cap output to ground. The probes played the role of such resistors.

On the DC out, now you put a cap after it, its other end is floating.

Thank you Salas; now I understand. Still learning. Two resistors it is.

It would actually zero when you connect to the amps load, but its not good to have a charge and then connect, accidents happen if an amp is forgotten on for instance and there is a discharge thump with DC component too.

I added the 1Meg resistors after the output cap and everything is as it should be. The blue hypno is now connected in my system and making good music. If first listen is anything to go by I'm really going to enjoy owning this buffer; so dynamic and the bass.......
