In 1973, I took 75.00 that I had made putting in 8-track players in cars and bought a Marantz 2213(believe that was the model) stereo receiver and a pair of Realistic 2 way floor standing speakers. I had a turntable also that I picked up later.

I remember I bought a pair of Klipsch KG3.5's and a Yamaha integrated amplifier. This is when Cd players were very new and i bought a single tray Teac.

I inherited an Empire Troubador turntable from my brother, a Scott "Stereomaster" 35 watt channel integrated (Tube) amp, and some large enclosures my dad made for me with Electro Voice 12's / 8 inch Jensens and Electro Voice horn tweeters (t-350's).

Had it in our recroom next to the pool table. Ahhh the memories... cranking "Born to Be Wild" and "Purple Haze" & "Eight Miles High", White Rabbit", ... Good memories, while my dad would patiently teach me how to shoot pool!

Was actually a very fun system back them.

AH the days when we though we new what sounded good:

Radio Shack all-in-one receiver, turntable with that huge plastic flip of lid and of course, an 8 track player!

At the ripe age of 16. Paid for by myself. Oh was I quite proud. lol.

Kmart bluelight special, a soundesign all in one stereo.

My first "REAL" Hi-Fi.

Man I loved that Hi Fi!

Is it outside the spirit of this thread to go back to the first radio I owned? I got it in about 1958 and it's shown here: [Link: crystalradio.net]

The second radio, a small portable, had two antennas. One antenna picked up signal for the tuner. The other antenna picked up AM signal, rectified and filtered it, and that provided the power to run the rest of the radio!

I ask because the topic might be about the first audio product or audio system we owned, not particularly stereo. I had:
late 20s Philco TRF AM console radio in 1963
tube auto radio I converted to run off house current, 1963
1948 RCA console radio, 1962-66
various shortwave radios
various 78 rpm record players that stacked up to a dozen records
A huge suitcase with a 78 rpm record player, radio, PA, and record lathe in it
...and finally we get to the middle sixties, when I built a Dynaco Stereo 120 (ah, you gotta love 2N3055 output transistors, because if you look at 'em sideways they'll short out on you!)
Got through college, starting working in audio sales in 1970, so had decent gear after that.

I did proudly own a red plastic transistor radio as a youngun! My first tunes. I tore it apart to see what made it work, and that was the end of that.


After that I graduated up to an RCS all in one record player with built in amp and speaker. Loved that thing and only had a couple of 45's I played over and over and over... Drove my mom nuts.


THEN I got the afore mentioned "Stereo"...

Mid 70's - Lloyds
Receiver, 8 track, turntable. Funky cool white and chrome speakers. All the gear was white with chrome trim. Even came with a glass and chrome stereo stand that was at least 5ft high X 3ft wide. Got my first records, Boston, Kansas and Rush.
After I moved out of the house I bought my first "real" stereo system. NAD receiver, Technic's tape deck and turntable, Kef C55 speakers.
Along with music from Floyd and others I too listened to Spyro Gyro & Mannheim Steamroller.

In 1971 I was in South East Asia(Thailand/Viet Nam). I was 19. I bought a Kenwood KR 6170 Stereo amp (had guitar input, mic input, and a rythum composer with reverb), a Pair of Sansui speakers and a Sony reel to reel tape deck (it had a built in amp and speakers and could play stand alone). Garrard turntable, a real POS. I gave all this to my best friend when I left for my second tour in SEA in 1972 ( didn't know if I'd be returning). This time I bought and brought back home a Sansui 4 channel amp, Sansui 4 channel reel to reel tape deck, Sansui 4 channel turntable and 4 AR speakers. The four channel was cool but you had to have Quadraphonic records (very limited avalibility) to decode to 4 channel. It would play 2 channel records but it was just dual stereo out. After a couple of years 2 channels kept going out and the factory repair sucked (never really worked right again). So I traded the system for a running and driving 1969 Triumph GT6+. The car was a blast. It was called a poor mans Jag. I now have the real deal, an 1969 Jaguar XKE. I still have some of the Quadraphonic records. I miss those days......

I had a JVC CD boombox with detachable speakers back when I was a kid.  I wired up about 8 pairs of speakers to it, in parallel, and somehow didn't destroy it.  I used to use it to make mix tapes.  Eventually the CD player stopped playing discs.  I spent countless hours listening to music on that thing.

Onkyo receiver, pair of Bose 201s, Sony single disc CD, teac dual cassette, white power strip, cheap cables, lamp wire for speaker wire, I was 16, bought it from circuit city, '91.

1981- pioneer SX- 6 reciever ( recently gave it to my dad to use in his shop) huge kenwood speakers with 15 " woofers, Dual turntable , Technichs turntable, pioneer dual cassette player with auto song search , Teac reel to reel, radio shack mixer, still have it, still works! (this is when I first started as a DJ) . My dad gave me his series IV Bose 901's.
Man I thought those sounded great ! Ha ha! I abused the crap out of those .

Big @ss Pioneer receiver, HK top loading cassette deck and this cool little triad bookshelf+sub speaker system.





Can't remember the model of the receiver but it looked very similar to this.
