New Amplifier

Worked on a new amp over break. It's not 100% done (missing some resistors) but here's a shot of the wiring to last you until then :)

Very nice Soren. Did you build the chassis yourself
with angle and flat aluminum ? The ground bus is impressive.

thanks! unfortunately the amp is already all packed to head off to college so i am forced to be more mysterious than was my intention...

the top part, if you were to see it, would have a color and finish kind of similar to that on one of these:

amazing what a ruler, some clamped wood guides, a jigsaw, and a lot of cursing can get you :) still have 10 fingers...

anyway as soon as i get back i'll plug it in and switch on the heaters to show you some glow.

Nice legs. I mean the angle iron. Err, aluminum. :)

Neat idea that I haven't seen before.

thanks! i figured the thin tek chassis metal needed support, then thought about letting some angle stick out beneath. feels nice and solid :)

the huge transformer in the back is the 10H 300mA input choke.
