Harman Kardon 930 Twin Power Receiver Pt 2!!!
Merry Christmas everyone. With the wood cabinet and power option this listed close to $700 in the day! HK was one of the first audio companies to recognize the unpredictable dynamic nature of music and designed their receivers w oversized power supplies ie duel supplies to respond to the dynamics! 👍
(Correction to my specs. The capture ratio of the fm tuner is about 1 db. The selectivity about 65 db. )👍
I say it has an effective frequency response of 4 to about 140 thousand hertz, because even at these extreams it’s still close to flat!👍
Half a century old and it can compete and beat most amplifiers today.👍
Upgrades include new output transistors (4) MJ21194G together w a complete recap w Panasonics for the dual power supplies, and Elna silmac II’s for all audio circuits. Along w NTE 199 transistor replacements for the phono pre amp. 👍
Order 4 electrolytic Panasonic 80v 6800 uF caps for the power supply. 12 each Elna Silmac II 20v electrolytic capacitors at 1, 3.3,.1,.47, and 100 uF for receiver preamp and phono preamp. Also 4 NTE 199 transistors for the phono preamp board.👍
Optional 6.3v led warm white fuse lamps (7) may be used for the dial area.
For those who have extreme courage!!! Try replacing all 8 transistors in the receiver preamp with NTE 199 transistors!!!! The receiver so modified will rip the paint off your walls!!! 👹👹👹👹

    Bought one off E Bay myself and it's not bad. The Meter does not work very well or at all and the Stereo light does not work. I have it in my shop but it does pick up static from tools that are plugged in. I also have an old CD player I might hook to it if I can figure out how. I would like to find some better speakers if I new which ones this unit will handle. Thanks for this video and I am a Subscriber.

    The Radio Shack STA-52 circa 1977 is a very nice looking AM/FM Stereo Receiver indeed! I believe that the STA-52 was engineered with 12 watts per channel RMS & the later model STA-52B was 16 watts per channel RMS!

    It is an IR remote which is delivered with the Technics receiver or amplifier. You connect the deck with the receiver so you can control the deck with that remote control. Synchro edit is to connect with a Technics cd player having that facility.

    Q-VOX is "QUATRAVOX". The gimmicky name Radio Shack called that feature when they built the STA-90. It was also featured in some of their other models in that era. I owned a Realistic STA-1000 amp with that same feature back then.

  • @cliffrhames3023

    Today, FM stations crank up the base to the max and that’s what causes base boom on these stereo receivers and many others as well. I have lots of off the air FM recordings from the 80’s that sound great compared to today’s over boosted base music.

    This receiver, nor any other Realistic receiver, employed "perfect loudness". Perfect Loudness was an adjustable loudness circuit found on the large integrated amps SA-2000 and SA-2001. There was an adjustment knob on the front "which allowed you to customize loudness compensation to various listening levels - the ONLY way a loudness circuit can function properly and as originally intended". Quoted from the 1978 catalog, page 38.

    • @billdurham8477

  • @stevewallace7397
    @stevewallace7397 9 місяців тому

    Great review! If the STA-90 didn't win any awards, it should have.😎 I have a 1976 model, and you're correct, the "Perfect Loudness" circuitry can be overwhelming at volume although I use it often at low volume to fatten up the end result. I've come to really appreciate this feature. All in all, one of the best bang for your buck recievers out there. Made in Japan by Foster Electronics (later Fostex). A true "sleeper".

    • @TheShackGuy
      @TheShackGuy 2 місяці тому

      Perfect Loudness was a variable loudness circuit found on Realistic integrated amps SA-2000 and 2001. It didn't appear in any receivers. The STA-90 was made by Foster Electric. Fostex was a brand name of Foster's, unrelated to stereo receivers.

  • @mjg263
    @mjg263 9 місяців тому

    I had one of these and I always thought it was such a nicely designed receiver (especially liked that it didn’t have those goofy volume slider controls). Unfortunately the FM section on mine had a problem and even when connected to my roof antenna it would only pick up a couple of strong stations. I ended up selling it to someone who didn’t care about FM, they just wanted a good amp that looked nice so they were happy with it. Never did figure out what was wrong with it but I bet they have a great tuner when working properly.

  • @mjg263
    @mjg263 9 місяців тому

    Nice honest little receiver. I have a Realistic STA-47 from around the same time period out in my garage. It’s a blazing 12 wpc or so, yet it sounds very warm and clear plus it can get very loud if called upon. The FM tuner is amazingly sensitive too. I don’t know how they pulled it off but it’s a real underdog and a winner in my book. When I was a kid in the 70’s we always used to bash anything Radio Shack, but if your STA-64 or my STA-47 had been my first piece of gear I would have been VERY happy. BTW the STA-47 is on the cover of the ‘76 catalog and I think it came out in late ‘74 for the 1975 catalog (they had a weird schedule for some products back then).

  • @tbird10030
    @tbird10030 9 місяців тому

    I have 2 Realistic STA 46. In first unit, the stereo light does not come on, signal meters barely move. Don't know yet if the light is burned out or if it's the weak reception. I've had this problem with Marantz receivers and was able make an easy fix by adjusting a certain variable resister explained in the Marantz service manual. In this case I have no reference to go by. __ The second STA 46 receiver Has low volume noise/crackling in the "right channel" when in stereo mode. However, when switched into "mono" both channels work fine. I sprayed the pots with Deoxit, but the problem persists. Can someone tell me what adjustments or fixes I need to make on both units. Any help or suggestion would be deeply appreciated.

    • @MyAudiostuff
      @MyAudiostuff 9 місяців тому

      Probably a bad transistor in the preamp of the second receiver.

  • @jeppoification

    What are the rca outputs in between the front and rear speaker outputs? I assume it's for QVOX as shown but how do you set up your speakers? Do you setup front speakers as normal and rear speakers with rca connections to get QVOX sound or how does it work???

    • @MyAudiostuff
      @MyAudiostuff 9 місяців тому

      The rca outputs are simply an alternative speaker hookup for the main speakers. The Quadravox is available through the regular speaker hookups and will be noticeable on the rear speakers when the circuit is engaged.

    Neat! Reminds me of my 1975 Realistic STA-47 I use out in the garage. Radio Shack was still using that old style Quasi-Comp circuit in some of their gear until the early 80’s whereas most manufacturers had stopped using it by ‘74 or so. Their receivers worked pretty well and had sensitive tuners though, and they met a reasonable price point.
