This is a really cool site. It reminds me of the old days when I used to build things (amplifiers, radios, etc. from scratch
or even from kits like Heathkit, Dynaco, Hafler, etc. Sean, just work on your soldering skills and you will be fine. It sounds
like a fun project. Send pictures of the different stages of construction if you can. I built a 200 watt solid state amp for
a project at UC Davis. The amp was built from scratch and the performance was modeled them we ran the circuit through
the SPICE program on the Burroughs mainframe and published the results. The paper was used as a study guide for engineering
students for years. I really miss my days working as an EE. The last couple of decades it has been mainly IT related projects and
I really don’t find that as interesting. I am thinking of renewing my amateur radio license and rebuilding some commercial and
military radio equipment for fun. I got my first license in 1969 but let it expire a couple of decades ago. It’s a fun hobby but it
got to the point that I worked with it so much work wise that the “hobby” aspect faded at some point. Have fun with the project
and if I can be of any help let me know.

I'm not sure if I'm venting or asking for help or what here.
It started innocently enough. I was going to build a FrankenLeslie. Took an oem Leslie 10 unit out of a dead and worthless Hammond J series spinet. (One of those horrible cheesy Hammond transistor bastards.) I'm going to build it a proper Leslie-like cabinet. I'm going to plug my A-100 into it.
All I need to do is build a simple and elegant power supply and amplifier to drive the single 8" 8ohm speaker.
I've been trying to read up on amplifiers and my head is just spinning. (Like the rotor should be!) I've spent many hours today on Elliot Sound Product's backend of of articles and projects. I got horribly confused in the first section of "The Beginnner's Guide to Amplifiers."
Thinking I should have majored in electronics engineering instead. I had no idea a simple amplifier could be so horrendously complicated. It, apparently, IS rocket science.

I guess the appropriate thing to ask is: Where should I be reading up or copying from or whatever to build a simple, elegant, amplifier that can take the balanced signal that comes out of a Hammond?
Thanks.
