I've decided to go with the 10 X 17 X 3, in steel. Next order I make, I'll get two of these and the bottom plates. Also some more rubber grommets for the xfmr lead holes (I had some on hand, but need 6 more).
I like to get the output trannies spaced out further from the power iron, even though the cores will be oriented 90 degrees apart, they were just too close on the smaller 12 X 8 chassis. Also, the board will be completely clear of the trannies, no overlapping.
Just a couple weeks ago, I got one of the small K502 amp kits, and mounted it on a nice red-painted chassis that was formerly the home for
an FM tuner with built in SCA decoder, that I found at a swapmeet years ago for a buck. The board is mounted on top, the trannise further back
and more widely spaced, and had room to put a 4 position terminal block for the speaker connections. This is for use with a CD player, or kicking up the sound card to a decent level. The original FM tuner and SCA decoder worked poorly at best, the previous owner had hacked the circuitry and made a mess of it.
No, the K502 isn't as good as the '35, but for the relatively low price and simplocity, it does an OK job. I built it up during lunch breaks at work, got some ribbing from the other engineers for dabbling in "Fred Flintstone" technology.
If I ever get the HWTs, it will make an interesting look, Pewter "hammertone" trannies on a black chassis. Maybe I'll have to do some custom pinstriping, too
