Matt's Ham radio and DIY audio website

Audio projects ranging from a class A 20W/channel audio amplifier to a 15" cylindrical sub woofer. I haven't done any audio projects for awhile, but you can still check out my projects on my DIY audio webpage.

I have been a ham radio operator for 40 years. Here is the construction page of a 600W solid state HF amplifier (about 70% done).
