Here is the heart of these mammoth record players, 6 tubes total, 5 speakers spread across 54 inches, fully opened up.
Reminds me of those low and long stereo consoles that every home had in the 60's!

Hi Bob,

I am very impressed how you're able to find these high quality stereo systems. Where on earth do you find them?

I'd love to see a restoration thread on how you accomplish such amazing work.

Tom

Hi Tom,
Thank you for your compliment!
Sometimes, that's all I need to keep these going.
As far as finding these, I look everywhere and stockpile the usable parts.
I would like to simply call it a labor of love!
These large record players are simply a study in American pride.
Back then, they just wanted the biggest and the best.
I am reminded of that every time I lift this thing!
It's like pumping iron.
52 lbs.
54 inches wide, fully opened up.
The sound makes it all worth it!
Bob

One could possibly say that Motorola invented the powered sub (wasn't a sub back then but same principle of bass being reproduced by a single speaker) unless others were doing the same thing before them.

Hi Tube Radio,
Interesting comment!
Motorola used the same separate bass output on several models, even smaller tubed chassis.
I guess they ran with that "3 Channel Sound" for all it was worth!
To me, looking back in retrospect, they wanted something that could compare to Stereo, but did it their way!
Innovative Marketing!

Suppose they wanted a way to get better overall sound quality.

Have a channel devoted only to bass which keeps the bass out of the stereo channels allowing the stereo portion of the amp to not work as hard and possibly have a little more undistorted output.

Plus you would then be able to optimize the bass speaker for the bass and the midbass speaker for the midbass and midrange which would give overall better sound quality.

Hi Everyone!
I just completed a project I have been thinking about for several years and finally accumulated the necessary parts to finish it.
I have several Motorola SP-29 record players waiting for restoration and selected the best from the bunch to build a custom SP-29 based SP-30.
The original SP-30 GL series cabinets were sort of squarish and lacked the finish and fit of the later SP-29 series IMO.
I had all the SP-30 GL components saved in a box, minus the cabinet, which didn't survive shipping years ago.
I transplanted everything into the stylish SP-29 cabinet.
This was not an easy task, as the original engineers did not envision this to take place.
Let's put it this way.....I had to do a lot of cutting to allow adequate clearance for the reverb tank and installed a better 8 inch woofer with a substantially larger magnet structure, not to mention, larger voice coil.
When it was all done, I could not wait to "fire it up"!
I was very pleased with the results and would like to share them with you.
Of course, I had to test it out with several records too.
Please enjoy Ol Blue Eyes performing " Come Dance With Me" and The Jive Bombers singing " Bad Boy".
Both tunes were played with the Vibrasonic control set at a very conservative 3.
Notice the "boinggggggg" at the beginning of the Frank Sinatra tune.

Very nice.

Bet it sounds better in person.

All your Motorola posts make me want one so I can see just how good the three channel sound really is.

These Motorola's are addicting!
I've been doing this restoration thing on portables for quite a few years now, and nothing sounds more robust then a Motorola SP series record player.
It must have something to do with isolating that 3rd or bass channel.
The clarity is so rewarding, and although it's not as deep as the modern sub woofers, it displays a colorful and believable bass output.
More than enough volume to fill an entire home, it doesn't mind being pushed to the higher limits.
As I've been saying for years, it truly reminds me of the stereo consoles that were 6 feet plus in everybody's home in the 60's and 70's.
I will drag this beast outside today and post a video of it playing, with a little more volume and reverb.
My neighbors always love me for that!
Thank you for the compliment,Tube Radio!

You're welcome.

I've found that sometimes if the bass that's there sounds good enough then the bass the device cannot reproduce isn't really missed.

Wow, that's an impressive collection! For the best demonstration, I'd love to hear it in person.

Thanks, Tom!
I took it outside today to crank it up a bit.
My neighbors always love to listen to my record players, so, I treated them to some Sinatra.
Today, he's singing "Come Dance With Me" and Somethings Got To Give".
I had the reverb control set to 3.5, bass and treble set to 6, and the volume was cranked to a little over 7.
Wanted to make sure everyone heard "Ol Blue Eyes"

Hi Again!
Just wanted to share some pics of my latest project.
It's still very much a rough packaging scope right now, but it will work!
Components from a Motorola SH-22 will be used.
Three channel, 6 tube amplifier, 5 speakers total.
6 inch mid range and 3 inch tweeter on either side, and a 6 X 9 bottom firing woofer will be used.
I used 1 inch spacers on the bottom face to lift it up for the bass tones.
All Golden Voice speakers.
On the bench, it sounds terrific!
Lots of cutting and trimming with my Dremel coming up!
I'll share a video of it playing and finished pictures.
