Okay, for you guys asking about these chassis's.
I looked up the all the cost that I have in these. There was raw Aluminum, CNC machining, and engraving. The front baffles say Commemorative Designs in honor of Gary Dodd as he designed these.
I have $115 in each chassis.
I can throw in the Cardas RCA's for $10 each. That's less than the retail for.
The Neutrik connectors are $15 a set (male and female).
And the tube connectors are $59 a set.
These little chassis are perfect for the Folsom amps.
I also have a bunch of the TDA7850 chip sets and circuit boards. These are what the chassis's were designed for. It's a similar chip set, but will output 50 watts per channel into four channels. You can vary the input coupling cap value to allow one set of outputs to be full range and the other can have reduced low frequency (filtered lows). That's what Gary was going to do with them. http://html.alldatasheet.com/html-pdf/233387/STMICROELECTRONICS/TDA7850/1944/1/TDA7850.html
I can throw in these chip sets and boards for another $20.
Oh yeah, the internal space is 6" by 5" and 2.375" tall.
