Sansui 500 Receiver-You Can Come Home Again

A year ago, an odyssey began, a trip back to the origin of my discovery of recorded music in the mid-1960s. This is the story of my brother’s music system brought back from the Vietnam war. A Sansui 500 receiver, Dual turntable and a pair of co-axial speakers that laid on the floor (we never got around to building their speaker boxes). All my years of high school this system played and many many a Friday night friends would gather with a new album, and we would play it, read the liner notes, and talk about the music and our lives late into the night.

After my brother’s death, five decades later, the only remaining part of that system, the Sansui 500 receiver, returned into my life. But could it be brought back to life? Yes, it could, our decades long stereo shop Hawthorne Stereo could do this through the connections and wonderful professionals they knew. While great, playing the Sansui 500 through our Spendor A7 speakers, I felt something was missing, those 16 Ohm speakers long gone.

So, I would look time to time, eBay, Craigslist, Hawthorne Stereo’s Used Room for vintage 16 Ohm speakers until it happened. One day a pair of NOS, still in box, with all papers and the critical design for a front ported speaker box, Pioneer 16 Ohm PAX-20E co-axial speakers were found.

Then I read the seller’s description and Déjà vu. They were purchased by a Vietnam Vet at nearly the same time and at the same Japanese PX my brother purchased his system. No, they weren’t the same lost speakers, but they were, perfect.

Tonight, I bring the finished PAX-20E speakers home, turn on the lava lamp, Sansui 500 and pass back in time. I will cue up Joan Baez to play “Forever Young” and as she sings, another voice will join her in song, my brother’s.

You can come home again.

Thanks all, this has been a revelation of sorts.

Is it the tubes? The restored speakers (new cones/voice coils, the glue had dried and coils were loose, tweeter capacitor)? Matching 16 Ohm speakers with the 16 Ohm tap? There is a synergy here. This system loves the human voice, and a wide range of music, though classical orchestra, "Jupiter" from "The Planets", not so much. Is it the 100 dB/watt efficiency? The mid and treble is very fine, and the bass can be too, but stops around 40 Hz.But, the bass is funny, some recorded material, it is not there as much and other recorded material WOW where did that lead in electric bass line come from, e.g., Doby Gray "Driftaway".

Social Media and the age of comparison anxiety, my modern SS system and Spendor A7 speakers," Better", yes but really as I listen to the same songs through modern and vintage systems, I think the more accurate word is "Different".

Which leads to the why?

Why restore and create the playback system of 1966-70?

A 1966 Ford Mustang fastback with a 289 V-8 and a four speed transmission would be destroyed by the least of the modern Mustang, but the modern Mustang can’t be a time machine. That 66 Mustang can. We who lived those years left our DNA in them, just as each generation does, but therein lies the cool. The arts constantly recreate themselves, music, movies, etc., they mine the past. With this vintage system I seek no more than to slip an 8-track into the playback deck in that 66 Mustang, to sing once more with the wind of those summer nights.

Take Care.
 
Excellent story and beautiful Sansui.

I just picked up a 500 that works and is in great cosmetic condition. After reading through many threads it looks like a full rebuild is in order
 
We have 15 of these great old receivers in the database. If you post your serial numbers we can add to that collection.

Will do Pete. It’s enroute to me and I will send the serial number soon. I’m shopping for a rebuild kit for the caps, etc and contacted Ben with Affinity (eBay) to see if he can bundle one for me. Beautiful receiver and it should pair up well with my AR XA turntable
 
I love stories like this. One of my favorite sayings is, “they don’t make em’ like they used to”. As I type this, I’m listening to my ‘69 Sansui 800, for the first time in a year or so. A ‘71 Au-222 is my regular player, but I sure am enjoying the 800 today!

Hey Pete I just received the 500 and it’s in amazing condition…wow. The serial number looks like it is 8K9611. After removing the covers it was a little dusty but no obvious damage.

All of the Suzuki caps are still in place, so my work is cut out for me. The fellow I bought it from says it works with audio but I don’t want to tempt fate by powering the unit up. I do have a DBT but not a Variac

Very nice! Thanks for the serial number. The 500 was being built during the transition from the old serial number format to what became the modern serial number standard. Based on the units we have in the database, 500s with the new format started in September 1965. Your 500 was built before that month. Enjoy!

Thanks for the information Pete. I’m really looking forward to hearing the tubes playing through my Forte II speakers
 
The speaker connections are very unique. Am I correct to match the speakers to the correct ohm rating by attaching the positive speaker wire to the correct ohm rating and the negative to the terminal marked with a C?
 
My local tech did the recap and replaced all of the bad tubes…wow this Model 500 sounds amazing. Comparing it to our Marantz 2285b, it sounds very smooth
