Hei, har du noe tips til gode phono plugger til å montere i chassiset slik du har gjort? Kjøpte et par billige kontakter fra Skutle i Bergen, de holdt bare 1 måned før de tok kvelden 😮
Hoy 6 de mayo 2024 compre una x $10,000 argentino practicamente regalada LENCO L78 solo le falta la tapa y pua....estaba publicada y me parecio una bandeja rara de ver y mas x el precio....y no me equivoque la compre justo xque el q la vendia me dijo despues q te la yevaste voz empesaron a llover de mensajes q la querian y le pagaban el triple para q se la guarden....safe yo era para mi....lastima no se puede mandar foto x aka....🇦🇷🇦🇷🇦🇷 bernal oeste quilmes
Hei, lurte på hva du bruker som jordingspunkt i mellom rca pluggene du monterte i plinthen? Vurderte å bare sette en skrue der med skive og mutter på hver side men det kan kanskje gjøres litt mer elegant? 😊
Heisan - skrue går fint, jeg har brukt disse : www.ebay.com/itm/163278963357?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=OjwHGMubSDO&sssrc=4429486&ssuid=CuLoKHSYRFC&var=&widget_ver=artemis&media=COPY. bananplugg med kontakt funker også👌
A very nice series of videos. I appreciate your walkthrough. Very informative. I have a question regarding the grounding. I recently purchase a Lenco l75 (very similar to yours) and I have problem with buzz noise (a huge peak at about 149 Hz). The noise floor is generally not too bad but the buzz is way too loud. I separated the grounding of the power and the signal and using the EU 3 pin power socket (just like yours). For the grounding of the arm I use the yellow wire attached to the arm assembly directly to a separate port (to be attached to the pre amp). The small jump wire that attaches the TT ground to the left channel was de-soldered. In my understanding everything is fine but the result is just awful. Any thoughts? I am using a Tc-750 Preamp and Ayima A07 for testing. The Amp and the speakers are quite alright as I use them regularly for another setup. I appreciate any thoughts you might have on this. Best, Ceena
the arm is isolated from the top plate as the pidestal is plastic - running the arm ground directly to the amp (not via the connecting board) should do the trick. If you still have a buzz, check that the arm ground is still soldered to the arm inside the pidestal, it runs from the underside of the arm, through the pidestal to the underside where a second yellow wire runs from arm to the connecting board. A test/search for error can be done like this: take a piece of wire and connect one end to your TT/RIAA ground. With the other end, touch the headshell, arm and other parts to hear if it disappears. this will give you the point where the arm ground is broken. Also, if headshell and/or cart is unmounted, you’ll get a buzz. hth - cheers
Hey thanks a lot for your prompt reply. I will take a look it and let you know. Interestingly that was my initial approach. I imagined that the arm should be isolated from the top-plate but once I inspected the inside I realized that the yellow wire running from the arm (I assume that is the ground of the headshell) was soldered to the body of the arm (connecting everything to the plate) so I de-soldered that one too. Anyway thanks again. Let's see if I bring it back to top. It would be a shame. The unit is in a very good shape. Idler wheel was in tact. motor runs on a solid 33.1 with very little Wow and fluctuations. @@drlencowich
Hi, once again thanks for your suggestions. Thought to give you a follow-up. I was able to resolve the issue which happened to be many fold! In short the Lenco's ground wiring was fine. My test amp (Ayima A07) was not grounded properly so I ran a wire from the housing to the ground power and that got rid of the 150 Hz. But then I was stuck with a 50 Hz peak which was very stubborn. I realized that the RCA cable that connects the TT to the pre-amp was picking up noise from the powerline (which was placed very close to the plug). Better shielding cable and away from the plug point solved the issue. Now the Lenco is brought to life and what a sound 🙂
Hello, excellent videos, thank you! When all back to its place, should idler wheel be tangential to the plater? Because mine in not... is there a possibility to adjust it? thanks
Hi - thanks😊 the idler wheel will not be tangential to the top plate, but should be (aprox) at 90 degrees to the motor axl ant platter. In the lenco factory, I’m told, they bendt the idler arm to fit this - but carefull - as not to break anything. I would do a test first, check for speed and wow - if ok, I would leave it👍
