Bad NOS tubes...
lewm06-18-2016 2:39pmJea48, Gold-plated pins are a sure sign of recently manufactured tubesThis statement is completely misleading and not correct. I have many vintage tubes with gold plated pins - from Telefunkin, Mullard, Siemens and many others... 
Possibly dumb question: can I use two cable runs for each channel, not bi-wired?
stuartkIf you double the wire as you have suggested then the result electrically is that is you halve the impedance of the cable. This may tighten the bass response since the impedance of the cable is halved.Try it, and use your own judgement. 
Vintage DD turntables. Are we living dangerously?
Lewm, I showed my tech Halcros photos at the time and he said no problem - there is enough web info to work the Halcro circuit out and you can solder through the gunk if you know what you are doing. Having said that he has a Bachelors degree in El... 
Vintage DD turntables. Are we living dangerously?
From a 6 Moons Review of the Walker...The base is crushed marble in a lead and epoxy resin and gorgeous. The Platter is 75 lbs. of encapsulated lead, the most resonance-free material known to man.It also used to be on Walker's website but I see th... 
What cart. for the Reed 3P?
thekong - I would think that reducing vibration to the TT may help to reduce some tonearm/cartridge resonance if there are external vibrations that are causing instability to the TT/arm itself. However the tonearm/cartridge resonance will still co... 
What cart. for the Reed 3P?
thekongThe "ideal resonance" of 8-12hz came about historically because it was below 20hz, i.e. well below the cut-off in most systems, and above 3-4hz. "3-4hz" is the typical resonant frequency of footfalls on a sprung timber floor.The resonance f... 
Tonearm recommendation
Lewm - When I’ve run lighter MM’s on the FR64 I used 12-13g headshells - Denon PCL300 & Audiocraft AS12 in conjunction with the lighter W170 counterweight. The last 2 MM’s I ran were the Glanz MFG61 and Victor X1 - these are medium compliance ... 
Need Klyne Audio SK-2 manual for dip switch set up
Here is a link to the SK1 dip settings.I’mpretty sure they will be the same.http://cheaptubeaudio.blogspot.co.nz/2010/09/klyne-sk1-phono-pre-preamp.htmlWith my SK1 I found the best way to set it up was to start with highest load and start with the... 
Tonearm recommendation
Fleib,Factory nulls for the Dynavector arms areInner 60.1mm    Outer 116.5mm ( VE is wrong )Dynavector state that their arm geometry is set for minimum lateral tracking angle error at the inner groove. Tracking angle error for Dynavectors using st... 
Tonearm recommendation
Addendum to post above - I also own a Dynavector Karat Nova 13D which is set up for Stevenson with its integral headshell.This should read "standard Dynavector alignment" which is a variation on Stevenson.  
Tonearm recommendation
dover: do you have right now on hand the 505?If yes just try Baerwald or Löfgren alignment changing the P2S distance from Stevenson. Then listen and listen in between ( B, L and S alignments. ) and return here to share your experiences there.If no... 
Tonearm recommendation
dover, no I don’t modified my 505 and the new set up is only 2mm ( around it ) on P2S and less than 1.5° on OA. The dyna specs are not accurate.Never mind, has no critical importance your posts but a misunderstanding by your part. Please don’t giv... 
Tonearm recommendation
Fleib/Lewm I calculated the effective length required to achieve a 21.5 degree offset with Lofgren A for the Dynavector arms. This would result in the cartridge being in line with the vertical bearings.Using the formulaEffective Length = (r1+r2) /... 
Tonearm recommendation
The reason some people find those zero offset arms sound good, is reduction of torsional forces on the cantilever. Do linear arms solve these problems? If and only if, they can maintain tangency at all times and otherwise behave as a proper tonear... 
Tonearm recommendation
The EPA 100 effective mass is 22gr., has a removable universal headshell that if we use something like the Denon PL-5 ( 5grs. ) we can mount with out modifications cartridge weighting to 17grs and additional to all those tonearm characteristics it...
