... and it's BIG
Here's a shot of the stock BeePre inside the new chassis.
Amazingly, as I play around with layout it is a challenge to make everything fit nicely on a 16" x 20" top plate! The CLCLC B+ filters take a a lot of space, plus the two new filament transformers and their recitifier/smoothing circuits. And moving the fil reg board closer to the tubes (located stock above the PTs).
My plan is do the layout "backwards": tubes at the back and transformers at the front. The BeeQuiet attenuators will be mounted on a plate stood off from the back wall panel, with really long extenders running through the center to knobs on the front wall. This way all the signal wiring is kept together at the back, with no long runs and nothing close to the transformers or chokes. I plan to add a dividing aluminum wall to separate most of the power supply stuff from the signal stuff (excluding C4S and regulators which will be above/beside the tubes). The chassis is just over 5" deep, so I'll have some room beneath/above the pot extenders for components if I mount the attenuators toward the bottom of the back wall panel. But a better idea, if I can make it work, is to mount the attenuators vertically, so that when looking at the front face panel the fine is located directly above the coarse. This would free up a lot of space. To make this work, I'll need to shrink the footprint of the attenuators to about 4 inches (stock is about 5). I think I can accomplish this by mounting them approx. 2" apart center to center, rotating them 90 deg., and by putting the connecting terminal strips adjacent to them rather than between and at the ends of them.
In short, it's going to look weird - but I'm ok with that.
cheers, Derek
