Does the top plate get very hot?
I ask because I happen to have a replicator 2 3d printer, which I believe should have a big enough print area to print a case for my crack amp (which should be here in a few weeks).
UPDATE: sorry, i wasn't very clear. the reason I ask why it's hot is because the PLA plastic that the printer prints has a fairly low melting temperature. different colors have different melting temps. (clear/white melts at a really low temp, and black has the highest melting point) didn't want to print a case (would take all day at a high resolution setting) only to have the hot tubes heat up the plate, causing the casing to melt lol
also, if i go through with this and it turns out, i'll post the sketch up on thingiverse so others can print it out if they choose they want to do plastic over the wood. (though I think plastic will look cheap compared to the wood which can be stained or painted)
I don't know the answer as my Crack isn't assembled yet, but looking at the resistors that it comes with (5W), there will be some good heat being thrown out. The top plate will help as a bit of a heat sink.
