Just acquired this turntable just because I should be able to control this with my logitech harmony remote via my luxman receiver (r115). I'm controlling a luxman CD player this way as well, so I thought what the heck, lets get an all one brand system from the mid 80s going. There's a 4 Pin DIN connection that allows the play/cut and cue up/down functions to be controlled by the remote. As such, I'll be able to turn on the receiver and turntable (plug the turntable into one of the receivers 4 switched outlets so it comes on too) and then play the record with my remote by pressing play and stop it by pressing stop, as well as pause/play by using the cue function. This should be fun and I'll put up a video if it all actually works out.
Lugged this guy as a carry on from Vancouver to NJ. Heres' the unit after a bit of clean up. There a chunk of missing vinyl veneer and a crack in the dust cover, both visible in the shot below. I also had to fashion a paper clip tonearm rest clip. Other than that everything else seems in good shape.
Here's the 'guts' of the unit. Such a tiny, tiny motor and a 1/4" pressboard bottom. The motor in my other turntable is about the size of a baseball and weighs what a solid block of metal plates an copper should. Looks like someone's been in here damping things as it's not the most solid looking plinth and no metal substructure. Also, the auto/manual switch/PCB has been removed as can be seen by the two standoffs at the top and the electrical taped set of wires just under the zip tie just below it. Plan to use it in auto anyway with the solid state setup.
Here's the bottom cover with plastic feet that articulate somewhat. The bottom panel is very thin. I'm thinking of bonding it to a 1/2" or 3/4" particle board or MDF panel of the same size to give the plinth some mass.
The platter has the same material applied, and is deceptively light despite it's tall profile....
I decided to put some black plastalina from the local michaels ($3 for 1 lb) into the open slots on top. Weighted each one so they were all 20 grams and pressed them in, so 360 grams added to the platter.
Finally, this came with no cartridge, so installed a Shure V15 Type V cart into the removable ADC-1 type head-shell and am awaiting a stylus (and 4 pin male/male DIN cable for the remote) to arrive in the mail and perform the overhang alignment before giving it's first listening test. Found a template for this in the PX-99 owners manual.
All functions work very smoothly and the platter gets up to speed in about the same 1-2 seconds after adding the weight as it did before that (showing by a green 'quartz lock' LED that lights up, and theres another green LED for the repeat function, which also works).
From my understanding this is the sister table to the Luxman PD-291. Looking at the service manual, the 291 has an aluminum clad top with a wood veneer base. The other differences are that the PX-100 has the 4 pin DIN for remote control via receiver and the PD-291 does not. This was determined by studying the service manual parts list and schematic. All other electronic components are the exactly same and the only other difference is the PCB part #s and a screw/bushing that's used in the PD-291 that's not used on the PX-100. Circuits themselves are exactly the same. I suspect the PCB part# differences due to not having provisions for the remote control circuit.
I haven't been able to find out much else about this table, other than a few posts stating that the motor is supposed to have very low rumble per an Aussie stereo review article in the 80s, so any information on this guy would be worthwhile.
Questions...
1. Any suggestions on what tweaks might be done to this turntable electronics? Replace electrolytic caps? I did find the service manual, but not the owners manual. Have requested that from Luxman.
2. Will adding mass to the bottom plate be a big help, as it does in the Thorens 160? I've heard this table has . a problem with resonance. Should I be damping the tonearm somehow? Too bad there's no anti-resonance counterweight like Dual has.
3. Any info on which tonearm this might be? I've read it's a micro seiki, but couldn't find a similar item at http://www.micro-seiki.nl/
4. Assuming this is a light tonearm and the Shure V15 is a good match?
5. Any other advice?
