For those of you planning on using BrianGT's PSU boards, I still have some 50VDC Snap in caps left for sale from a bulk purchase I made for some other members.

Ok, it seems the concensus is for no major changes, so I will just redo the drill file, and mail it over to Mark.

is it me, or are those metal strips really Fat ?
Anyone ever experimented with putting a metal layer on copper ?
I have these gorgeous copper strips i'd like to use for the Krell PS, and would like to sheet them.
Calling Mr Electrolysis,long distance.

Silver plated some Copper Bus bars, not sure If I would do it again.

Thats great! I will be in Idaho this week again but will have the laptop with me.
Jacco,
Those are alumnium bars approximately 4.750" long X 1.675" wideX .375" thick(you convert to metric). They provide some heat sinking for the bridges and keeps the buss wiring very short.... yes that are about twice as thick as the original Krell bars were. Nuttin wrong with that though. BTW, there is anti-oxidization compound under the screws and star washers. Yeeee-haaaaa!(we still say that out in the west sometimes)

Hi,
how about tinning them with solder to delay corrosion.
Anyone know how to plate with real tin? To eliminate corrosion and solderable as well.

The Anti-oxidation compound prevents corrosion. Were they anodized then they would be insulated.

You can have this done farily cheap by having them zinc plated, the copper over the zinc. After that a simple tin plating should cause you no problems to do your self.

Hi,
two suggestions for the Wiki build pages.
1. How to calculate the resistors that control the quiescent current in each of the stages. Particularly for those who have a different transformer voltage.
2. What range of quiescent current suits each stage and what effect does each have on operating parameters and sound quality.

If it came down to that I would just use gold plated copper bar instead. It wouod be easier than all that plating.....

Alu don't plate easily----far from.....
If you use copper bars, it would need a layer of rhodium first, to enhance adhetion.
Why not use the alu as is? It is fairly non-corrosive by nature, polishes easily - and so does copper..........................
HMMM----Don't say the gold would enhance the sound......????
