Talking My first chip amp

Just finished 2 channels of my first gain clone. I am pretty excited. I used a PS that BrianGT had to test it out and it worked great. Sounds great so far. Now I have to finish the case and the PS.

I just had to share it with someone else since this my first real electronics/soldering project.

Not to bad eh?

Looks a heck of a lot better then the first stuff I soldered together, good work.

So I only see 4 resistors on there, is this a Peter Daniels type minimal GC?

And what are those 2 pieces of clear wire on there?

Yes, you are correct. I started using the schematics off of National's site, then I worked Peter's design into it.

The clear stuff is Teflon to protect the wires when I ran them across one another.

To tell you the truth, I really was not sure that it would sound great but it did.

Looks good Pretty good amplifier to build in 6 hours. We will tackle the chassis next.

I was there when he built it, too, and I think it sounds great. I should finish my own first project (leach amp) soon, and I've had a lot of fun building it. I think I'll build a gainclone soon, myself, and bi-amp my first speaker project. Great job on the amp.

Hey , you guys should have an amp Build-a-Thon.
Put up posters and get payment in advance. Maybe some official endorsement by the dept. or club so people don't worry about getting ripped off. Put together say 20 kits- a single transformer for 2 channels, Dale resistors, Panasonic caps, plastic knob terminals, surplus CPU heatsinks. They bring a (cookie tin?) enclosure about the size you specify.

All the potential DIYers put 'em all together one night til 2 am under your direction. Get a few extra parts for those that fry something.

A lot of fun seeing people so excited about making something so great "all themselves" You could guarantee success-I mean the worst case is you have to rebuild someones botched effort.
