It's a nice amp. You'll like it. I taped it in 1980 or so. Just like everyone else, I made subtle changes. A couple notable ones: metal film resistors where possible. 10 turn pot for bias adjustment. I added audio ramping and thump supression as well.
The power supply makes a big difference in the sound. I used a 20 AMP constant voltage transformer and the AMP sounded great and the hum was horrible. I then changed to a somewhat under rated quad custom made torroidal transformer and the AMP was quieter, but not as bassey. I accidently mad a mirror image of the board and because the design is so symmetric, I was able to use it with a few external changes and switching the NPN and PNP transistor positions. Go for it. --- j3r3m3l33 <[EMAIL PROTECTED]> wrote: > Has anyone KiCAD'ed this amp: > > http://users.ece.gatech.edu/~mleach/lowtim/ > (http://www.pavouk.org/hw/leachamp/en_index.html) > > The second link's author said he did it in Eagle. > > By all accounts is a nice unit when built.
