  1. Seems that TheWretchedWorld ran Dutch auction. He agreed to sell me this kit and you are now selling part of what he sold me. Keen to know how much you paid for the complete kit, as this does not sound right to me. Cheers Grant
  2. Noooo! 🤯 Nice to know about the Sunfires though 😎. Fantastic system and GLWTS. Gn
  3. Turntable is the Premier and tonearm looks like one of these: https://www.vinylengine.com/library/graham/2.2.shtml Very serious. Cheers Grantn
  4. Beautiful piece of kit: http://www.scheu-analogue.com/turntables/ Cheers Grantn
  5. Congratulations on your excellent choice of tonearm.😉 Works beautifully with the Lenco. Cheers Grantn
  6. Okay simple answer is in the range of 33 to 36mm, excluding platter mat. Long answer, I have L75, L78 and G99 platters and 3 bearings. One bearing is standard and 2 bearings are "non-standard". Variations with same platter and different bearings in the order of +/-1.5mm. Variations with same bearing and different platters in the order of +/-0.5mm. The reason for the wider variation between bearings is the "non-standard" bearings were made to "account for" the difference between 3mm thick G99 pan and the 4mm thick PTP5 plate. On top of this I run with mats including 3mm cork, 4mm standard rubber and 6mm paper rock. I hope this helps and does not confuse the issue further. Cheers Grantn
  7. Bingo, now that is a number we can get you, but not as precisely. 75, 78, 88 and 99 are all slightly different I believe. Will do a little bit of disassembly to report in the morning. Cheers Grantn
  8. Not sure if this helps, but because the PTP6 bolts to the top of the plinth and the bearing bolts to the underside of the PTP plate, the distance between top of platter and top of bearing flange is the measurement you are actually after. I assume you already have the bearing and platter. cheers Grantn
  9. While this is correct, I always thought that the problem was, within the audio spectrum, plinth resonances (and armboard resonances) will always exist. Over the nominal 3 decade band of audible frequencies, I thought that nothing was "rigid". The statement that one should make an armboard out of "rigid" materials to "eliminate" resonances, would therefore seem to me to be unachievable. While pursuit of reducing resonance is correct, there will still be resonances to deal with. The most informative resonance measurements I have seen, are those of the tonearms that attach to an armboard. Not the tonearm-cartridge combination, but the arm tube resonance. The "best", most rigid of arm tubes, usually achieve first resonance somewhere in the second decade, none get very far into the third decade, without starting to "rattle". If it is going to rattle, I want it to be a nice rattle. This management of resonances might be achieved by constrained layer damping, material selection, or a combination, even with arm tubes varying in cross section from one of my favourites, the Grace G707, to the extremely well engineered Copperhead. The former a glorious set of compromises and the latter a pursuit of engineering excellence I can only admire, including the way it harks back to Gates broadcast arms. Neither, from my understanding represent absolute rigidity throughout the audio band. While I do not disagree with the aims of an arm board to hold the arm pivot to the platter bearing "rigidly", this will not be achieved without some resonance to be dealt with somewhere in the audio band. I recall living quite happily, for a very long time, with the resonance management afforded by the much maligned arm board of the LP12, although more for the "lossy" fixing, than the actually constrained layer damped construction. Of course Linn have now pursued a more rigid option, go figure. 🙂 Cheers Grantn
  10. So you had to turn the amplifiers off because the inductors in the speakers were glowing red? Man that is a serious amplifier. 🤣 Joking, seriously jealous. Respect Grantn
  11. Hi Orpheus Fascinating back story and great where you have arrived on your journey. ESL57's and Cissy Houston on one of Herbie Mann's albums was the trigger for my journey, which included LS3/5a's and peaked for me at Acoustat 1+1's driven by the highly unlikely Atma-sphere M60 OTLs. This combination had huge compromises, but one of those was not bass extension. The following is a timely reminder to us all that we all make choices and compromises, that suit ourselves and circumstances, even the designers. https://darko.audio/2019/04/andrew-jones-on-the-realities-of-loudspeaker-design/ I am currently loving my wife's Kef LSX speakers. One day I will get back to Acoustats, but until then I will keep enjoying the music. Cheers Grantn
  12. Just a bump to see if this (remote volume etc) is still a possibility, or past into the not enough interest basket. 🙂 Cheers Gn
  13. Well it depends what you are after, completed turntable, or self build. Peter is, or has built turnkey tables using the PTP5 providing speed change without platter removal: http://www.ptpaudio.com/solid12.html lf it is a self build you are planning then the 6 probably provides best combination of flexibility on layout and function. The choice will come down to what you want to pay for a turnkey option and your imagination for a self build. my G99 continues to play very nicely, while my PTP5 remains alot of ever changing ideas in my head. YMMV. Cheers GrantN
  14. A picture or two... This is the 6. The 5 does not have the little slotted tab towards the right front of the plinth. This is the 4 and the following is the motor island. The latter not to scale of course.😀 Gn
  15. My understanding is the 4 is a full plate, square, with a motor island cut out to isolate motor from top plate. This has provision for speed adjustment outside platter. The 5 is the motor island and a small plate with bearing mount and idler position slot only. To adjust speed you need to have an electronic speed adjuster, or lift the platter and unlock, move and lock manually. The 6 is same as the 5, but has an additional slot extension that allows adjustment of speed outside the edge of the platter. Cheers Grant
