[Amps] High voltage rectifier / capacitor board material?

[Steve Katz]

I think the temp rating of those cutting boards is fairly high, as you can place meat that was just cooked at 400F directly on the board without damage or discoloration.
 
Or, at least I do that!

REPLY:
In my homebrew 3kV power supply, I used a high density polyethylene cutting
board I bought in WalMart's kitchen department for a couple dollars. Works fine,
but I don't know about it's temp rating. In my design, I used a fan to cool
things down and I placed the capacitor bank right in the outflow of the fan, so
temp is not a problem. Be careful if you place it somewhere else.
