Here’s an interesting receiver I bought a couple years ago off of eBay. Purchased it prior to learning from Hi-fi Engine and other sources of information on the web. I was pretty certain this was a prototype, but actually others just like this are out and about there.

Never seen a small form factor Technics receiver like this with so many features.

- 2 VCR/video inputs with video switching
- Phono, CD, and tape inputs
- All feather touch controls
- Remote control
- Equalizer with spectrum analyzer
- StereoPlex, Loudness, and VHS EP tape speed audio enhancement circuits
- Badge says that this consumes 380 watts to operate, so you divide that by four that’s close to 100 which would be 100 watts per channel (if you’re not aware, that’s a reasonable gauge to understand how powerful and amp is if you don’t know much about it or can’t find info)
- Integrated cooling fan
- Volume and other feature indicator lamps (unnecessary idiot lights, which are fun to watch)

It has an STK amp chip, so at its age needs to be run cool. These chips are notorious for failing at any time.

The technical specification badge is on the bottom of the unit because there’s no room for it in the back. That’s what made me think it was a prototype.

Video shows a quick demo and then there’s some color commentary afterwards if you stay for the ride.

Have a great weekend everyone!
