EICO Model 377 Revisited

Recently, as I was working on an audio amplifier project, the time came to test it with a frequency-controlled input signal in order to determine if it handled tone control properly. This was just the job for my recently-restored EICO Model 377 Sine and Square Wave Generator. Unfortunately...

Reviving old equipment

Every now and then, I am handed the opportunity to breathe new life into old gear. So far this year, I have revived a Heathkit IT-28 Capacitor Checker and more recently, an EICO Model 377 Audio Signal Generator. Both are tube-based and built to last. Unfortunately, both had problems when they came into my hands.

More after the jump.

Compiling...

Just a quick note to let you know that I'm still here. I'm busy with several projects, so I haven't had to time to post anything of note. Never fear! I plan to post something soon. Honest.

Hello, World!

Welcome to Retronics, my blog about... wait for it... Retro Electronics.

Ok, well, maybe that's not ALL it's about. I enjoy lots of modern-era stuff, too.

What I *really* enjoy is the interesting things you can make if you combine old-era electronics with modern stuff. We're not just talking Nixie-tube clocks driven with Atmel microcontrollers running C (though those are awesome). I'm talking about breathing new life into old stuff that has been written off as junk. Combining vacuum tubes with solid state electronics. Putting old equipment back to work. Up-cycling. Whatever. The sky's the limit! (unless we're talking about rocketry or balloon cams ;)

I intend for this blog to be a home for some modest build logs of my own. I don't have much free time these days, so updates will probably be slow in coming. I'll post some images of projects that I've done in the recent past, and also try to post some things about my current interests.

Questions/comments are always welcome. I'm always looking for a better/cheaper/faster way to do things and if somebody learns something along the way, all the better!
