STD160 Volume Control

[paradisecs]

I have a working STD160 and it has the motor inside for volume control.  What I am lacking is a remote control.  Anyone have any information on this piece and how it hooks up?  Given the age I know it's got to be wired, I assume you could run it a long ways to keep behind the bar.  If I can't find one I'd like to try and make one.  I guessing it's a simple toggle switch for up and down and maybe mute with wiring running to the system but I haven't found any wire diagrams showing how to hook up the external part, or even the part number.

It is pretty simple -just four wires plus one more for remote reject.

Here is the switch I use for commercial locations: www.parts-express.com/dpdt-heavy-duty-toggle-switch-center-off-momentary--060-376?utm_source=google&utm_medium=cpc&utm_campaign=pla

We use a center-off momentary. The motor runs only as long as the switch is held in either up (volume) or down.

Thanks for the info. I'm finally getting back to working on this unit now that the other units I was helping on are done. Do you think using arcade microswitch push buttons would work? I was thinking about making a box using 24mm arcade buttons that match my coin ops I have for use as the remote. And to clarify, the 5 remote wires go to the bridge on the volume control motor and not a plug on the amp itself?

Using push-buttons won't work--should someone push both up/down at once, you should pop the 2 amp fuse inside the SHP., if you are lucky and don't blow the amp first ! Yes--If you have a PRVC-4 B unit, the connections go to the terminal strip on the VC. Ron Rich

Does anyone know if a Rockola remote can be used for this Seeburg PRVC? If so, how would the wiring connect? I have manuals for both, but of course they don't tell how to connect to the competition.

Patrick,
Depends on what you are calling a remote ? If, as I suspect, it's the remote volume control switches, sure-- On the Seeburg Brown is hot 25 VDC, black is ground, and red/green are up-down.  White is reject. I think, RockOla is the same but check that with a meter. Ron Rich

Patrick, any of the motorized RVC pod's can be used with any other in that era. I have a Wurlitzer RVC controlling an HVL w/TSA-7 amp.

Just trace it out via the link i provided.

Ron & Rob: thanks for the help. I'm getting ahead of myself here asking about a volume control since all I've done so far is get and read the complete manual set from VG. But in spite of what the manual states, there is no cabinet-mounted volume control shaft accessible at the back like there is on every Rockola I have. There's no hole in the cabinet behind the PRVC mounted inside. So I'll wire one of my Rockola motorized volume control pendants.

Hi Patrick,
What are you reading? There was no volume control shaft, "at the back" on any Seeburg for years--
How are you controlling the volume now ?

[jukerocks]

Well, that explains a few things. There's no control now. Would I be correct thinking that, with no volume controller, there would be no sound? The mechanism will select, pickup and play but no sound. As for the reading, where they discuss the slip clutch in the volume control I was assuming (and I know what THAT means) that the manual control was there. I'm pretty amazed how little working with Rockolas prepared me for this machine. This seems to be so far ahead of, say, the Rockola 442 of about same time. I'll wire up a RO control as described earlier just to see what happens, but my plan for this jukebox is to go through it as thoroughly as possible to clean everything from cabinet to contacts and familiarize myself with what's inside guided by the manuals before I get too concerned what works and what doesn't.

I must be pretty dense but, there IS supposed to be a volume control mounted on that machine's rear wall. It is toward the center and right above the steel channel that reinforces the back.

Look at the amp, is there something plugged in the 'volume control" plug?.

Hi Rob,
You are not dense- -this time ! If there is nothing plugged into the Molex 12(or 15?--don't recall) pin, volume control housing, someone stole it--It was installed there at one time ! Since the gentle man says there is "--no hole--" I need to assume that the VC motor is installed onto the VC, and is blocking that hole, as it should ! I can't assume which version motor is installed on it--if a code B, version, there will be a 5 wire terminal strip attached to the motor housing (gear box). Ron Rich

[jukerocks]

Both right. Molex plugged into amp connection marked "volume control", terminal strip on the motorized unit. Just to clarify, this is the USC-2, and the motorized volume control is mounted to the left (from the inside) back wall above the main and cancel switches.

[Ron Rich]

Patrick,
You said this was a "STD- model" ? If a USC model, it uses a PRVC-3, if someone has not changed the plug-in, volume control itself ? ( they are interchangeable--almost-- electrically) The difference is that the USC VC is mounted into a metal frame, while the STD VC is mounted onto black plastic. If this is a USC control, it does, in fact require a "pin" be inserted between the three balls inside the black plastic housing, at the rear of the VC. This VC, with or without a motor assembly, will not fit the rear wall of a STD model phono, with out modifying the mounting studs.

Ron, it is 15 pin. BTW: Are those available?
