Denon DP3000 DD turntable
You should go to the website “Vintage knob” for baseline info. I believe the dp3000 was a midrange model in the first of two series of DD turntables made by Denon. The top model was DP6000.  You should check me out on this, but I think that early ... 
Manley Chinook with (very) low output MC ZYX?
Thanks, JT. FWIW,  I think Evanna goes by “Ms”, not Mrs. Sometimes we swap out parts just because it gives a feeling of control. But without a schematic and the proper knowledge, it’s a crap shoot. Manley won’t give out schematics even to professi...

I would guess that using a blank LP would give you a baseline for AS force, because I am guessing that the skating force on a blank surface would be a bit less in magnitude compared to that of a stylus traveling in a groove, where the contact poin... 
Curious about the difference in what I’d hear on different tonearms
I'm still reeling over the Adam Schiff comment.  Who needs that here? 
Manley Chinook with (very) low output MC ZYX?
Sorry, instead of RPMs, I refer to Op Amps.  I was messaging by voice and Siri screwed up Op Amps into RPMs. 
Manley Chinook with (very) low output MC ZYX?
 Where are the RPMs in the circuit of the Chinook?. So far as I know, my steelhead uses discrete transistors plus triodes throughout the audio circuitry. So I am wondering what is going on with op amps in the Chinook. Perhaps they only serve for t...

Raul seems to be my personal critic, following me around on these pages to disagree or debunk what I might have written.  Raul notwithstanding, I have no problem with anyone setting AS any way they want to.  I was merely re-quoting a fact: blank L...

Yogi, blank LP is not a good tool for setting AS. The skating force is due to the friction of the stylus as it passes over the vinyl in the groove. A blank LP by definition has no grooves. Therefore, it does not present the same friction related r...

Another way to set AS: Start with the very lowest amount that your tonearm permits, but not zero.  Gradually increase from that starting point until you have no audible tracking distortion in the R channel.  (R channel distorts with zero AS, so yo...

1.  There are at least a dozen useful test LPs.  Depends upon what you want to test for. The Cardas LP is a good one to have.2. Yes.3. Are you kidding? 
Vintage DD turntables. Are we living dangerously?
Haven't had a response from Chakster about the noise, but here are some more details about how I eliminated the faint rubbing sound I had that was due to the rotor rubbing on either the inner surface of the top cover (rotor too high) or on the sta... 
Japan Trip - Looking For Shopping MC Cartridge Recommendations
Eastern Japan, which includes all the major population centers like Tokyo, Yokohama, Nagoya, Kyoto, etc, operates on 100V/60Hz, not 50Hz.  This is fortunate for all of us in the USA, because all we need is an inexpensive 120V to 100V stepdown tran...

Beautiful workmanship, Totem.  Congratulations on your artistic taste and craftsmanship.

Mijo forgot to mention that your empirical finding that you need much less AS force, in terms of grams, than VTF is absolutely to be expected.  The notion that if VTF = 1.5, then AS = 1.5 is antiquated.  Setting AS = VTF will nearly always result ... 
Vintage DD turntables. Are we living dangerously?
In my research, I never came across a communication from Victor wherein they suggest that the bearing "never" would need service. This is in contrast to the Denon DP80, where Denon do warn customers to leave the bearing alone. (But I daresay they ...
