Hi all,

I am building an Aikido Pre-Amp and am going to use solid state rectification. I am planning on attatching diodes to a heatsink which will then be mounted on top plate of chassis along with TX's, Caps, Choke etc. Will mounting the heatsink on top plate be ok? Likely to cause any problems?

Cheers

You probably want to make sure the diode anode as well as the cathode are insulated from the chassis. What's the diode physical appearance?

Sorry, not too much info on that link.. shoulda read it completely first. My bad.........

Maybe try a Fairchild Stealth diode, some people are reporting good success with them and they can be had in 1200V 8A To-220 package from Mouser for $1.95

I may just go that route instead of the Mur4100e as the FS do not need snubbers to keep them ultra quiet. (as reported, but not by me) (I have no practical experience with either of them)
