Technics SA-300

Well, we can’t all be monsters right? The Technics SA-300 is no monster, but it does fulfill its purpose. This little guy produces 35 watts per channel with no more than 0.04% total harmonic distortion. So, with some fairly efficient speakers it can produce some nice clean sound for moderately sized room. Plus, it looks nice too! The brushed aluminum face plate and black inset knobs give it a high end, sophisticated appearance.

Offered from 1978 until around 1980, the Technics SA-300 retailed for about $300. It features a 41 click step volume control, low distortion bass and treble controls, high filter switch, loudness compensation switch, and dual function tuning meter.

The SA-300 really does look nice when lit up. The amber back lighting of the tuning dial is both clean and elegant.

The output stage on the SA-300 is direct coupled which means it uses no capacitors. This results in a nice, tight, solid bass response right down into the lower frequencies. And, believe it or not, the SA-300’s FM front end utilizes a dual gate MOS FET design and a 3 gang linearly variable tuning capacitor. This gives it excellent sensitivity and interference rejection.

It weighs just over 15 pounds and measures roughly 16 x 6 x 12. The cabinet has a walnut grain vinyl over pressed wood. The SA-300 is a pretty good little receiver. No, it’s not going to blow the doors off of any room but it will make a good garage or studio unit. Some people feel the sound is nice and clean while others have called it two dimensional.

The Technics SA-300 is a decent receiver but it’s not in high demand. It has its place in the vintage audio world as an entry level receiver or everyday workhorse in the garage. It doesn’t handle low ohms well and requires pretty efficient speakers. If you find one at a good price though, it can still be a desirable piece of equipment. A fully serviced unit in really nice condition should run about $100. A decent working unit will cost $50 to $75.

    1. Looks like 3.3 amp aren’t so common. You could try 3.15 amp. It might blow quicker if you really crank the receiver up but they should work. I don’t know what the length of that particular fuse is so you’ll need to measure it in millimeters. HERE are some 3.15A 125V 20mmx5mm fuses on eBay. I’m sure there are some longer versions available as well. RadioShack or Mouser probably have 3.15 amp versions as well. The slightly lower amperage shouldn’t be a problem – they will just blow slightly easier than the 3.3amp versions. Just make sure to match the voltage, which I believe is 125 volt for the SA-300, and the length and width (probably 5mm x 20mm) so that they will fit properly in the fuse holder.

  1. I have this receiver in great condition except one side of the stereo does not work with the speaker we tried. Is it worth it to fix or should I just sell it cheap? Its been in storage for over 20 years.

  2. Years ago I had an SA-300 and one of the power amps blew out. I replaced both left and right with RCA Darlington 50Watt power amps. The power supply handled them just fine and the receiver works great to this day.

  3. I myself have a Technics SA-300. The right side just hums and the left works just fine. Being that it has two power amps, i was just wondering which one inside the unit is the right amp that needs replaced. Thank you for any help you all may provide.

  4. Peace
    Can’t recall how I became interested in vintage receivers but I now have a SA-300 and a Sansui G 8700db.When I put the 300 with decent speakers and music from bands only, it’s really nice.

  5. Hi there. I have a Technics reciever SA-300 with no sound output in both channels. Only humming in both channels . I found that a resistor R625 (120 ohm) was roasted. So I changed it and now the reciever works in left channel, but still no sound from right channel. Only humming in right channel. I think there is the same problem in the right channel, but I can´t find the faulty resistor . Can anybody help please? Thank you.
