What interesting or unusual gear has passed though your system during your audio life?

Lots of cool stuff.

Maxell AE-320

No regrets, but I would not recommend it in 2021. I still have it. Box, instructions, small brush, cover/stand, mint condition.

In the similar tone, TDK HD-30 (red type). It did make sound and it did have a LED. It still looks and works as new. I mean, the LED still lights up and chirping sound is still there. I never noticed difference after using it.

An N.E.W. DCA-66 amplifier. It’s powered by four 18 Ah batteries. Didn’t sound too bad. It’s not in my system right now but I still have it. It was making some strange noises and I need to investigate the cause. Hopefully it’s a small issue.

@mkgus  I also had NEW DCA-66! Recently sold mine to a guy who was going to refurbish. I had issues with the charging system, can't recall the exact issue, want to think it was diode issue. Mine was making strange sounds when I had the issue, screeching sound if I recall correctly.

Interesting, that’s the same sound I am hearing! How did you like the the amp? Due to some issues with my preamp, I feel like I never got to drive it properly and never truly heard its full potential. If you ever hear back what the exact issue was, please pass that information along. I would like to get it up and running again one day.
