Closed AC-300 paired with Sony ss-h550

So I discovered this at Miracles Occur ReSale Retailer in Cottonwood, AZ for about 45 {Dollars}.

Technically a suitcase! These metallic toes have springs in them.

Unique foam items held up surprisingly effectively. They maintain the platter in place and shield the needle throughout transport

I might been trawling via FB market and Craigslist on the lookout for a classic package to get began with after I stumbled throughout this itemizing and fell in love. Makes an attempt to google returned only a few outcomes at first look, together with a reddit put up from 2 years in the past with a query and no solutions, so I Figured I might consolidate all the data I discovered about this unit into one place to assist anybody else who runs throughout one among these!

What Is It?

Packing Foam Faraway from platter and headshell and lid eliminated

The Hilton Audio AC-300 is a turntable and stable state amp manufactured between September 1974 and August 1986. It’s designed to be luggable and to resist the abuses of a dance corridor and transportation. It has springs within the toes to dampen vibration from the dance flooring, they usually declare it could actually play with out concern as much as 15 levels off axis. I do not know what yr this one is, however fortunately the brand new house owners of Hilton Audio have uploaded all the legacy manuals and data on their web site:

What was it used for:

Hilton Audio produced turntables and amplifiers for sq. dance halls beginning within the late 1950s. They modified arms within the 80s after which once more in 2014. They now not produce turntables, and solely produce a single amplifier in the intervening time. The mic inputs are for the dance caller to direct the dancefloor.

The Particulars:

Rear left I/O

Rear proper I/O

(Flip over twin needle design of the 89t)

    • 1 mil is a mono dimension. It would work on stereo microgroove however could gouge or scratch the grooves.

    • 911-DD77 is a 0.7 mil stereo suitable cartridge is accessible from Voice Of Music for about $25. This won’t output stereo sound, however will accurately monitor each mono and stereo vinyl and output mono.

    • All these cartridges simply slot in and sometimes function a needle on prime and backside so you possibly can flip the cartridge over. This may be two of the identical needle, or a 3mil needle for taking part in 78s and so forth. (do not combine them up).

    • No, you possibly can’t convert this to transferring magnet with out a hell of plenty of work together with wiring in one other pre-amp stage.

  • Tonearm

(Platter eliminated to indicate motor drive wheel)

    • Customized design, headshell will not be detachable. Most likely not replaceable if damaged with out plenty of work

    • counterweight is manufacturing unit put in at 8-10g which is a bit excessive for this Ceramic Cartridge. They selected this weight to assist constant monitoring in a rickety dance corridor setting. It’s adjustable by screw however has no commencement. I used a digital scale to set mine to round 6g.

    • Antiskate spring. unknown what the g is, doesn’t seem adjustable aside from changing the entire spring.

    • There may be an autolift mechanism BUT it requires a wired distant to make use of, and is ONLY suitable with 45s. If used with a 33 it can carry into the report and scratch it. Fortunately it can’t be activated with the distant disconnected. I’ll take away this fully (It is the rectangle on the precise aspect.)

    • There isn’t any auto return nor auto cease.

  • Motor drive and platter

    • So I do not know whether or not to name this direct drive or not. It is a repeatedly variable synchronous motor. The motor drives a rubber wheel which presses straight towards the underside of the platter by way of spring stress.

    • Velocity Management by way of a sliding lever which strikes the drive wheel from the surface of the platter to the within of the platter thus altering the RPM. The motor itself runs at an absolute fixed pace.

    • Platter is stable aluminum I imagine? Foam mat caught to it with adhesive. It is sized for 45s however 33s trip on it fantastic. It pulls straight up off the turntable. Beware there is a ball bearing within the shaft effectively.

    • There strobe is on the underside of the platter and is mirrored by a mirror in just a little window which doubles because the on/off mild. Sadly 33s cowl this window.

Strobe in motion. Set to 45rpm accurately and the higher dots seem stationary. vice versa for 33.

Entrance Management Panel

    • Velocity Selector

      • Repeatedly variable RPM pace lever. Transfer the knob as much as enhance pace. Mine was fairly correct to the labeled RPMs primarily based on the strobe.

      • Below 30 RPM and the drive wheel disengages from the platter. Set to OFF earlier than turning off energy. It ought to latch into place at OFF to forestall jostling throughout transport.

    • On/Off swap. This can activate each the motor and the amp. There may be not a option to flip simply the motor off, however sliding pace management to below 30 will disengage the wheel from the platter.

    • Phonograph quantity and tone knobs. It is a 300 watt amp, so it can blow out most family audio system in case you crank it, thus my inexperienced, yellow, and pink hazard zone labels. (The pink zone continues means past that as you possibly can flip the knob 300 levels or so.)

    • Monitor speaker Quantity controls

    • Output Selector

      • Setting this to elevated DOUBLES the present output quantity. Meant to be used with 300 watt rated audio system in an enormous dance corridor. Contemplate it a devoted blow your audio system swap.

      • Tandem units the monitor outputs to be paired to the principle outputs for a complete of four primary outputs. Used to arrange four banks of audio system in a big dance corridor.

    • Microphone tone and quantity controls

    • Meter Studying Controls (subsequent to the needle clip)

      • That is basically an output quantity meter. Imaginative and prescient of it’s blocked by a 33.

      • Regular is used for low quantity, Low is used for top quantity. (low sensitivity. Complicated I do know)
