Tranfiguration Orpheus description

Mark, if your friend has a 60 ohm load preset on his phono preamp (Manley?) that should be ideal since it's only 2 ohms from the optimum (62.5) I'd start at 47 just for comparison purposes, but I think he'll be happiest (after break-in etc.) with 60.

Nobody I know who has experience w/ MC carts has ever found one to settle in before 100 hours min. regardless of the published numbers. Tranny V/W owners I know agree their carts took about 125 hours befor they stopped changing, although I acknowledge the first big bump is at about 50 or 60 hours. I don't know why the manufacturers are so sloppy about this. It's the same with their published load recommendations, except for van den Hul, who actually does give optimum load values for most of his carts.

Are you really going to leave while your electrician is working on your house? Is he a relative?

Nsgarsh,the electrician will be DONE,before I leave.I do want to get to my pal as early as possible.
The pre/phono is a fully maxxed out,and totally rebuilt(by Great Northern Sound)Audio Research SP-15.All new Black Gate caps/Siemens CCa's in phonostage.A KILLER unit!!!A total rebuild,over stock unit.
A question,for you,and if Bc3 is still lurking.....My friend tells me that the distributer recommendeds a tracking force at the 2 gram limit,as best.I never liked my Tranny beyond the highish 1.8's(1.82-1.87,for me).My friend has my exact arm/table.BTW,the distributer,also,has a 2.2.Just coincidence.
What tracking force do you use.Just curious,as obviously set-ups vary,but the recommendation of "not lower than 1.95" doesn't ring right,to me!
Best!

Mark, my thinking about VTF is somewhat similar to my experiences with SRA: that it's difficult to find any two of the same model cartridge, that are identical in either of those characteristics.

You can physically see zero SRA, if you have the patience and tools, so no problem there. But with VTF, there is no practical way to "see" the coil's position with respect to the magnetic flux field. However, its (the coil's) optimum position can be inferred by measuring the cartridge's output for a given test tone at slightly different VTF settings.

I do it using the VU meter on my tape deck, which is not refined enough a tool to find the actual highest output point. So what I do is look for the VTF settings just above and just below the (assumed) optimum that yields the same meter setting.

So for the Tranny for instance, we assume the optimum VTF would be (theoretically) 1.9 gm, halfway between 1.8 and 2.0 gm, according to the manufacturer. So let's say you take a meter reading of a 1 kHz tone (Cardas record) at VTF 1.8 gm, and you adjust the meter to give a readable number like 0 VU. Then you increase the VTF ABOVE the optimum to where you again get 0 VU. Let's say that turns out to be 2.1 gm. The average (between 1.8 and 2.1) would be 1.95 gm. And at 1.95 gm, the meter should read slightly higher than 0 VU.

Even using this crude method, I determined my Tranny W had the most output at around 2.0 gm (with slightly less output just above or below) That was just after break-in, and I'm going to do it again just to see if anything's changed -- it certainly wouldn't surprise me to find it now requires a little less VTF.

Of course VTF also affects tracking, but I've always held that if a cartridge isn't tracking properly anywhere within its specified VTF range, something's not right with the setup or with the cartridge itself.
.

Nsgarsh,basically,after doing technical stuff(guage reading of downforce,and all other measured parameters),we ALWAYS use a "set" series of LP's,to make final adjustments(everywhere)by ear.
I like to have a good idea where the cartridge "sets up",and then listen for a couple of hours(actually these sessions go for an average of six to eight hours),guaging the timbres of music,etc,on these discs.
I wind up having to "fotz" around with the fluid/downforce/vta,about a zillion times before the night is through.Guaranteed to take place this Friday.I'm already in the gym,training!
This time around,thanks to the great post by Doug Deacon,we will pay closer attention to antiskate,beyond a setting,on paper,or with the usual test records.
I cannot wait,for Friday!I LOVE checking out stuff that has the potential to improve my own set-up.With my friend,here,this is a perfect scenario!Yet,I will go in open minded,and independent of preconceived notions.I don't think I am actually as obsessed as some of my posts indicate.
BTW,as a little "tease"(just for fun,and believe me,I'm really not taking all this too seriously.Just hobby fun),my friend mounted the "O",yesterday.
Based on how much "over the top" raving he does,for almost any new "chacka",he gets,he is not overly impressed here!!
Of course,this means nothing,with break-in,and his very rough set-up,but I figure we can have a bit of a fun "cliffhanger",for the moment!
Best

Mark, I can't seem to remember if you said what your initial impressions were of your V, but everyone including myself was a little surprised/disappointed with their Trannies at first, until after 50 hours or so. And it just happened again with someone else who purchased an O, so I'm not surprised your friend was underwhelmed ;--)
