  1. Observe (eg listen) first, measure second - is the basis of good scientific methodology. Cheers, Owen Dark Lantern blog - http://darklanternforowen.wordpress.com/
  2. Just a wee update.... We have a new laser-cutter for the SS frame & plates. This is a new test-batch of plates, just arrived. Looks clean & tidy, no burrs, burns, dimensionally v good.... Cheers, Owen Dark Lantern blog - http://darklanternforowen.wordpress.com/
  3. Hi @charlie_bird, a a quick summary.... Our DIY Ultrasonic Record Cleaner was inspired by ideas & work done by others on the 'net (see p.1). A couple of us developed a prototype into a 'kit' (see P.2). Many kits enabled us to place larger batch orders (SS laser-cuts & parts) & then offer attractively priced kits. (Metal lasercutting is contracted out to an engineering shop, plastic moulding is done by my son, other parts are ordered in. Some machine work, cleaning up, pre-assembly & packing etc is largely done by me. We cover our costs + a bit for our
  4. Hi @Pipey - you can ultrasonic clean quite well with just plain water. The surfactant adds some 'detergent' action esp. if your records are v dirty & speeds up air-drying by surface filming. If you vacuum-dry, then the latter is un-important. I think the surfactant/detergent cleaned vinyl tracks better afterwards too. I'd avoid unnecessary contaminants.

  5. Hi @VinylChef, @2Brix - MC cartridge magnetic generators all tend to resonate ('ring') a bit at v HFs, so it is usual practice to 'load them down' a bit. As mentioned above, something in the range of 5-30x the coil impedance is a good starting point. eg. typical low output MC cartridges have coil/source impedance of only 5-10 ohms - this is how the typical 100 ohms MC loading has come about. The Hana EL, with is coil impedance of 30 ohms, has something in common with the venerable Denon DL-103 (both are Alnico magnet MCs) which has coil imped. up at 40 ohms. So
  6. @Steve M. - thanks. That arrangement seems to work fine for you - the SP-10MkII chassis weighs 9.5kg, so that mass should provide a good measure of stability. And supporting directly under the TT chassis frame (without an additional plinth) should result in impressive clarity, I'd imagine. As an experiment only, consider removing the black painted bott. cover box & support directly to the alloy chassis underside. (You may need to locate the fr. LHS door stop a bit to the right.) The bott. cover box rings a bit. PS. I have a Transfiguration Temper W my
  7. Hi @crtexcnndrm99 - it's not really 'research' , just using my ears as best as I can. Unfortunately I have no experience with Lencos or idler-drives in general (although I just happen to have a Garrard 301 here right now), so I probably can't offer much that's helpful. With TTs, often it's a case of enhancing or maximising the strengths of the particular design. With idler drives (I imagine not dissimilar in strengths to rim drives (like the TransFi Salvation that I last used)) there is a good sense of 'leading edges' & 'drive' to the sound - unlike bel
  8. Well actually, we know that everything in this game is relative.. Depending on your ears, your setup.... as said, the OP should just trust his/her own ears. IMHO & IME (40+ yrs messing with this stuff), there is a big jump in audibility of information between conical & elliptical. And, depending on those other factors, another big jump is poss. from elliptical to narrower stylus profiles. And there are many so-called 'line contact' stylus designs , some more radical that others- weinz, shibata, vdH, geiger, micro-line, replicant....etc (Not to mention
  9. Greetings all, I rather like the stripped-down 'skeletal' approach. But however you run your SP-10, be sure to support it as rotationally rigid as possible. PLL controlled high-torque DD decks like this need as rotationally rigid & stable 'frame of reference' as possible, for the speed error correction to work with as low flutter as poss. You will hear the changes, improvements, when you optimise this aspect - both externally (TT chassis support & fixing-down) & internally (the DD motor internal fixing to the SP-10 chassis). Just IMHO,
  10. Hey @adamg - trust your own ears, not what others say. With an elliptical stylus cart. like the E3, you will be hearing audible differences. As @kelossus says. start (with top of cartridge) parallel with the record - with most decent quality cartridges, you shouldn't vary much from there. You may need to re-adjust (by ear) after some hours 'running in'. The SL-1200 is a decent DD TT & the Jelco arm should only improve it. Enjoy.

  11. I found them! 0.86g each, 7.9mm Dia. x 6,5 H, with a centre hole ~1.6mm Dia. Cheers, Owen Dark Lantern blog - http://darklanternforowen.wordpress.com/
  12. Hi @Ingolf - apologies, I just cannot locate the AS weights that go with my Hadcock GH228 tonearm, sorry. I'll continue the search, they must be here somewhere. Cheers, Owen Dark Lantern blog - http://darklanternforowen.wordpress.com/
  13. Hi @balk2117 - I was given the following link recently: It's the only one I have at the moment, will let you know if I get any others. https://www.aliexpress.com/item/32240043990.html?spm=a2g0o.detail.1000060.2.76ca1428elQZJs&gps-id=pcDetailBottomMoreThisSeller&scm=1007.13339.146401.0&scm_id=1007.13339.146401.0&scm-url=1007.13339.146401.0&pvid=d3e07bec-7188-4ad6-ab85-6f983ec84c83&_t=gps-id:pcDetailBottomMoreThisSeller,scm-url:1007.13339.146401.0,pvid:d3e07bec-7188-4ad6-ab85-6f983ec84c83,tpp_buckets:668%230%23131923%2358_668%23808%234094%23129_668%23888%
  14. Greetings @georgesgiralt - That 6L tank looks exactly the same as ours - model PS-30A (see last image). Cheers, Owen Dark Lantern blog - http://darklanternforowen.wordpress.com/
  15. Hi @Pipey - no problem, we have just received a new batch of some of the parts. We can usually have a kit packed in 2-3 days. Kit price is A$149 + airmail $16. (Can vary a little with exch rate.) Kit parts are as per pic below. If OK, just Message me your postal name & address & confirm your email for Paypal. (A paypal request will be sent only after your kit is packed ready to ship.) Assembly is mostly self explanatory, but we include instructions & some cleaning tips & information. Feel free to ask any Qs.
