Default Newbie with ST-8600 Tuner

I just bought an old Technics ST-8600 Tuner, over 20 years old.
I hooked the Output [Variable] on the back of the Tuner to the
Tuner input on my amp. The sound is lovely, even without
any antenna (yet).

But I'm confused by the other jacks at the back of the Tuner:

Output T A P E D E C K A M P - T U N E R 4 CH MPX OUT
Variable Rec Out Playback LineIn LineOut Horiz FM Mulipath Out
Vert
: : : : : :

so there are six x 2 (L-R) = 12 jacks at the back of
the unit. Tape Deck Playback seems to have extra shielding.

I have a tape deck, but it is connected to the Amp.
Actually, I've run out of Amp inputs, so if I can somehow
connect the Tape Deck via the Tuner and make the Amp think
the Tuner & Tape Deck are just a Tape Deck, well, I'd be happy.
Is that the idea?

On the front of the tuner, there is a rec/playback switch
with three positions:
amp
source
tape

Also, I have no idea what the Amp-Tuner jacks are for.

And finally, the jacks at the far right are COMPLETE Greek
(but not 2004 Euro Futbol Champions) to me.

Thanks!

Variable output is a regular audio output controlled by a volume control,
probably on the front panel. Connects to the "Tuner" input, or any other
high-level aux, cd, etc input of a preamp or integrated amp.
Rec (record) out and Playback are obviously for a tape deck, and strongly
implies the tuner is equipped with a Dolby decoder, which could also be used
with Dolby FM broadcasts, which never really took off. The "Line In" I've
never seen on a tuner, but sounds pretty obvious. It's another aux level
input. Line out is probably a fixed level output to go to your preamp.
Vertical and Horizontal out ARE used for checking for multipath, using an
oscilloscope, so I'm not sure why you'd have a separate "FM Multipath Out".

A tape deck connected this way could only record from the tuner, and in this
case, from another auxiliary source connected straight to the tuner. It
wouldn't record other sources such as phono, not directly, anyway.

The 4-ch multiplex output should be the detector output, to be used if a
4-channel broadcast system were ever implemented. (It wasn't.)

OK, works great. A knob at the front (calibrated in dB) allows
five positions (-20 -10 0 +3 +6). I have it set at zero.

Rec (record) out and Playback are obviously for a tape deck, and strongly
implies the tuner is equipped with a Dolby decoder, which could also be used
with Dolby FM broadcasts, which never really took off.


No sign of the now ubiquitous Dolby logo on this unit.

The "Line In" I've
never seen on a tuner, but sounds pretty obvious. It's another aux level
input. Line out is probably a fixed level output to go to your preamp.


A knob on the front labelled "mpx hi-blend" has three positions:
off auto manual
Would that be a clue? I don't know why a tuner would need inputs.
In fact, I tried LineOut to my amp, but heard no signal. Maybe it
is fried, or maybe internally protected only to work when there is also
a lineIn ???

Vertical and Horizontal out ARE used for checking for multipath, using an
oscilloscope, so I'm not sure why you'd have a separate "FM Multipath Out".


Maybe that last set of jacks has more than one purpose.

A tape deck connected this way could only record from the tuner,


The rec/playback three-position (amp source tape) switch? Might that
not send the signal (if in the appropriate position) from the amp
lineIn to tape out?

and in this
case, from another auxiliary source connected straight to the tuner.


Hmm, so maybe I'd connect the CD player to the amp via the tuner now?
I wish I had a manual!

It
wouldn't record other sources such as phono, not directly, anyway.

I'm still confused, but thanks, Mark!

I think I saw am owners manual for one of these on eBay a while back. Check
over there, as well as the completed auctions. Try both ST-8600 and ST8600
without the dash. Maybe you can contact a winning bidder for a copy.
Or try a Google search. Ought to be a manual out there somewhere.

On ebay, I didn't find any manuals for sale (or sold), but did find
two units without manuals sold by the same vendor. This was his sales
pitch:

"Low-noise direct FM-to-tape deck system sends pre-emphasized signal
to deck for recording, with de-emphaasis in playback. Built-in pink
noise generator for accurate level settings of tape deck. Unique pilot
signal canceller permits virtually flat response to 18 kHz, without
interference. Four "Flat Group Delay" ceramic filters and 6-stage IF
contribute to "wave form fidelity". Separate control and IF circuitry,
with dual-level FM muting ("normal" and "deep"). Switchable auto or
manual MPX hi-blend circuit reduces noise on weak stereo broadcasts.
5- gang FM variable tuning capacitor. 4 pole MOS FET front end.
Buffered MOS FET RF linear mixer. FM/AM linear dial scale. Output
level control. 2 tuning meters. FM multi-path output, 4-ch MPX output
for discrete FM broadcasts."
