I found a nice set of Infinity 1001A speakers. The crossover adjustments were loose and needed cleaning. While inside, I replaced the np caps in the crossovers, due to age. These are low power speakers with rear firing tweeters. The power rating for the Infinity 1001 speakers is 8-50 watts RMS. The nominal impedance is 6 ohms, and the sensitivity is 89dB @ 1 watt, 1 meter. The frequency response is 70Hz-22kHz +/-3dB. Boy, do they sound nice!
I've been in Amateur Radio since 1974, and still find new and interesting things to do. I like to build, restore, and operate on the air.

Hickok 536, pt2
This is part 2 of a Hickok I picked up. After some testing, I discovered some tests were way off. After disassembly and a quick check, I found the #83 rectifier to be very weak. I built a solid state replacement and fused it, and all was well. I also installed a 3-wire safety power cord, and began cleaning.

D&A Phantom Repurposing...
Whilst on the road, I'll update this a bit. This will ultimately be a bandswitched 80-10m GI6B amplifier. This is pt2.. I finally finished refinishing the outer cabinet with a nice wrinkle black surface. The face & inner cabinet will be an Ivory White. Here's a few pics.
Firebird Amp, pt2
I'm using this time to upload some pics, while on the road. I made a bit of headway in repurposing and refinishing the cabinet from the old Firebird amp for the new build. Here's a few pics...
Sanding the inside of the rear panel...
