Motorola Golden voice & HK33B speaker

B

biscuithead

Me likes the eargasm retroplasm...
I just picked up a Motorola Golden Voice console and an separate speaker cabinet HK33B. The main unit has 4 Jensens, and a date code of '57...
The cabinet speaker has date codes of '58 and the grill cloth and design is slightly different...
Were these sold together? The speaker is missing a badge that might of said "stereophonic"... Was this stereo or mono?
I haven't yet gone through the motions of bringing it up... and I haven't done any research on the other components...

Need a pic of the amp(s).
Normally during this period, if it was stereophonic it'd prominently proclaimed as such.

I always have such issues with uploading photos... Lets see if this works...

The separate speaker cabinet has its own amp in it. The turntable has two RCAs, one that leads just to the separate speaker...

If the cable coming directly from the phono, is going directly to the separate speaker, is the amp in the speaker only good as a mono phono pre?
 
I have a hh scott with a center channel, I was hoping that I could use this speaker for the center channel since it has its own amp....
 
Some brands such as Packard Bell had some designs where they employed a separate companion speaker for stereo. These units were usually mono in the AM & FM departments but would use a stereo turntable which needed another amplifier to achieve stereo.

You will notice that when you are listening to the radio, it only comes out of the main unit because it is mono, but the turntable is a stereo turntable. You can listen to records when just using the radio unit, but you will only get half of the stereo program.

Yes, you can use that separate speaker w/amplifier as its own mono system and you can use it as the center channel for your Scott.
 
Here's some info on your extension speaker and its amp:

http://www.radiomuseum.org/r/motorola_hk_33b_ch_hs_701.html

"The Motorola Model HK-33B is an AC Operated 5 Tube Audio Amplifier and speaker system to be used as the right channel when converting Motorola models 5K11, 5K21, 5K23, 6H26, 6H27, 6K13, 6K22, 10KT12, 13KT15 or 15KT24 to stereophonic operation. This model also included a stereophonic cartridge and all parts necessary to make a complete stereo conversion of above mentioned models. Cabinet is Blonde. This model has Qty(1) 12" PM speaker and Qty(2) 5" PM speakers."

It also references the schematic used in the HS701 amp, found in Sams Set 464, Folder 13. I do not have it, but it should not be difficult to find. Even without it, changing the caps value-for-value would probably enable it to work fine for years to come.

Should work fine with as a center channel amp and speaker, although frankly I've never understood the necessity for one.

The idea of a center channel was to fill in the gap when the right and left speakers were placed too far apart. Seems nowadays it's just a novelty like having speaker phase switches on some of the old tube integrated amplifiers. It is also perfect for a sub woofer amp.

I use the center channel on my H.H.Scott LK-48 with a mono amp and speaker when I am out in the yard doing yard work. I just put it on the back patio. No need to lug a pair of speakers outside to listen to stereo recordings when I am doing yard work.
 
Proper name for such speaker/amplifier cabinets is a Stereo Companion or Companion amplifier/speaker. Such units were add on extras on early Stereo ready consoles which could be bought with the main console unit and if the owner wanted to could be Stereo right away or upgraded to Stereo as the owner could afford or desire to.

Right on! That explains the speaker extension wire only going to the turntable.
...and it explains the build date of '57 on the main unit and '58 on the speaker.

Thanks much!
I can't wait first to employ the speaker as a center channel on my 299C...
I have some mid-late 50s High Fidelity magazines that I've been reading, and it seems that when stereo was first introduced a lot of folks felt that there was a "void" in the middle. After years of listening to mono, from just a single spot, people must have felt that where their stereo was positioned, was where the music should come from.... I want to replicate that.

I like that idea... maybe I'll get one of those "high quality" rock speakers for the back yard and hook it up with a switch to the center channel on my 299C...

I have so many Consoles... is it an injustice to separate these two units? I was thinking about selling the mono unit and keeping the speaker....
But I do feel some responsibility to keep them together...
