ppcblaster - I would keep the shunt current around 100 mA if staying with those 'sinks. Stay around 20 ohms or so for those current set resistors. I ran mine that way for awhile. It would live a long happy life, and sound great. You'll certainly need more substantial heatsinking if you decide to "drop the hammer".

Thank You,
Good to know,
I have a box of heatsinks plus we have Russ Boss here in the forum somewhere. I am going to go with bigger HS's.
Say, can anyone tell me if it is OK to use the MUR 840/60 instead of the MUR 120 in the "non hot rodded" DC-B1? I have every intention of building the Hot rod, but thought I would make sure its good standard, then go to full throttle.
Maybe just build it hot rod from the get go?

Of course, they are diodes after all. They will do the job. Just put the 10R 5W, use the box's floor as sink, and it will do OK.
Thanks for the reply, figured I'd just check that out. 10R 5W it is!

Updated build status
...Hotrod modification installed...
Also the Lightspeed was modified. The onboard 7805 is gone and he got his own "Salas Shunt Reg."
What i could hear is......Chapeau
An externally hosted image should be here but it was not working when we last tested it.

The Heatsinks are from Fischer Electronic typ SK68.
I use the 75mm version and shorted it to 60mm, so they fit perfect to the mosfet´s.

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.
