This is what I have accomplished so far with my amp. I have the channels running, but the cooling block, transformer, fans, bridge, and filter caps are not yet mounted (but I would bet they will be tomorrow). Also, the mains wiring and plumbing are not yet complete. The two Leach amps seen here are only two of the 6 channels the amp will have upon completion. I'm still waiting for some ordered parts in order to complete those channels, which are partially of my own design, but are heavily based on ESP Project 3A. They will have +/-35V supply (separate transformer) and will be capable of about 200W (but I'm thinking of using 2N5686/2N56484 on two of them to really get some power into low impedances). The boards for these measure about 2" x 5", and will be mounted on another cooling block in front of the Leach amps. Their incompletion is the main reason why so little progress has been made, I really wish my parts would hurry up. That, and I have been working on my speaker boxes and also dabbling in some other most interesting things (high energy pulses, I got a defibrillator capacitor and some other large caps the other day, but am still working on a good way to switch 25kA @ 6kV
).
The front and top panels of the amp are made of a very shiny silver anodized aluminum. The front pannel includes a power switch, master volume, levels for bass, mid, and trebble, recessed levels for each channel, stereo/mono/left mono/right mono, balance, input selector, clipping and power lights, 1/4" headphone jack, (hopefully) VU/PPM meters, and maybe anything else anyone can think of. There will also be the capability to switch defferent channels around to different active crossover outputs, and these outputs will also have RCA plugs on the back. Total RMS power output from this amp could easily exceed 1kW, but it will never do anywhere near that for the speaker system I'm building now. There should always be room for upgrades though.
