As I said this was my third one. It actually went pretty smoothly. I had no protoboard templet to follow like I had with Tangents great walkthrough, so I had to come up with something with 2 single op-amps and it ended up working, after a change or two. I am no EE and my design cannot stand much scrutiny, but it worked.
I then added the meier modified crossfeed circuit that I had been doodeling with for a long time. Plus, I had to learn to solder all over again.
I am old (55) and work in GM truck plant ( paint dept )..... I can paint a heck of a race stripe on the can, but my poor fingers are all burnt up.
Besides the cold joints, burning most of the insulation off the wire, etc,etc,,,,the dumbest thing I did was get so frustrated at my first amp ( only one channel would work ), that I ripped it apart ruining the opamp only to realize that the only thing wrong was that the r5 jumper on the right channel had fallen out.
The dumbest thing I did on my second build (tle and 2 x9v's) was bring it into work to shrink the heatshrink with heatgun I have here at work. I had the whole thing smoking. All the wiring is shiney and melted together ......still works tho.....
Anyway thanks to Cmoy and Tangent for the introduction. I have a great respect for the minds on here. The designs, the soldering (some of it is a work of art) and mostly the great sound that I am getting back into lately and really enjoying.
Good luck and good listening.
