Rega's anti skate scale is notoriously inaccurate, better to find a starting point with the cartridge holding on a blank disc and set it by ear for best dynamics from there, which will probably be a slight increase from the initial setting. If you use the land between lead out grooves for the initial setting check there’s no writing engraved on it first.
two problems with turntable
First time poster here. First of all, thanks to the group for providing some insight as to problem solving as well as your experiences with various brands of audio gear. This sight, has been very informative over the years as well as entertaining at times.
My system:
TT-Acoustic Solid, White,(no longer in production but similar to other Acoustic Solid models), WTB 370 arm made by REGA, Ortofon Quintet, Red. This TT isn't common in US as they mainly sell in Europe, Asia and Canada
Gold Note PH 10
Innuos Zen MK3
Bryston BP17 cubed with DAC
Bryston 4B cubed
Vandersteen TREO CT
Vandersteen Sub 3 (2)
Cables IC-Audioquest Yukon, Speaker-Cardas, Power-Audioquest NRG Y3
Room treatments-GIK and Acoustimass panels
This system was put together over the past few years. All components worked perfectly very well until recently. About five months ago I broke the red lead wire on the tonearm which is the right side (+) and after the wire was replaced and sent back by a reputable dealer, I notice the left channel plays about 5-10 db lower than right channel. The dealer says that if I bring the entire TT back to the store, they will analyze completely but they're over an hour away. This problem only occurs with TT playback and not digital playback and has been this way about two months. The other issue I have is with anti skate. The recommended VTF is 2.1 to 2.5 and it's currently set at 2.28. The optimum setting I have found for anti skate is just above zero which seems odd because most set ups call for anti skate to be set similar with VTF. VTA and Azimuth settings appear to be spot on and the right channel plays perfect. Cartridge alignment was set up properly with the protractor provided. The Gold Note has two inputs and I've tried both inputs with the same results.
This forum has some extremely experienced and sharp minds and I hope that one or more of you can help me solve this issue.
Thanks,
George

THIS LP is perfect for antiskating adjustment and everything else including tonearm/cartridge resonance test. |
The lead idea was logical seeing as how it happened. Think of the odds, the phono stage goes out right when the cartridge pin is changed. Switching the leads the signal did not follow the lead so it can't be that. Has to be either the phono stage or the interconnect from the phono stage to the amp. Or the RCA input on the amp. Always fun when something coincidentally goes wrong at the time something else is changed. |
Problem solved.... lessons learned I'm grateful for all the replies which inspired me to keep trying to fix the problems. Late last night I switched out the AQ balanced cable I was using between Goldnote phono pre and Bryston pre to AQ RCA cable and all the sound and details came back to life. The main difference is that you lose about 5db of gain from Balanced to RCA. Fortunately for me, I dug up a spare set of AQ Balanced cables and now the sound is back to original. I checked the original AQ balanced cable and it was clean and the pins weren't loose but the sound just wasn't right. I guess the lesson here is that a relatively new cable can look good but sound bad. Regarding the AS problem, this is what I learned. On my tonearm, WTB 370, made by Rega, there is no correlation between AS=VTF. I recalibrated the VTF to 2.28(recommended is 2.1-2.5). For my AS testing, I used Johnny Winter's album, Second Winter, which has no grooves on side 4. The best AS setting that worked is just past 0. The stylus doesn't move at all through most of the record. The pull toward the spindle is of course stronger on the inner grooves closest to spindle. There's always a compromise with AS setting. For my listening test, I used "Revolver", Mono, 2014 RE, Mint condition. On a track like "Love you to" you hear the distinct sound of sitar and tabla which are very unique. On a track like "Eleanor Rigby" the strings sound delicate yet clear. Sound level between L and R was perfect, super quiet record, no distortion detected. Special mentions here: @chakster I ordered the test LP you mentioned, thanks @yeti42 I agree with you, the scale for AS on the Rega tonearm isn't reliable using their numbers. At least not this model. @millercarbon, @elliottnewcombjr Agree with both of you, the best AS setting is when it sounds just right. CASE CLOSED |
