Herron VTPH-2 Phono Preamp
Dear Stereosforgeeks,You would need to stipulate the input impedance of your headphone amplifier. 
Kenwood L07D turntable and control unit
Chakster, Dr. Stearn is no longer refurbishing L07Ds. (He is an orthopedic surgeon in real life.) Bill Thalmann of Music Technology in Springfield, VA, would work on it, but I do not know that Bill would want to build a PS from scratch. And if he ... 
Kenwood L07D turntable and control unit
Dave, I always thought the tonearm had a family resemblance to the TOTL Micro Seiki tonearms. I cannot recall their model designations, but the bearing housing on those tonearms appears very similar to that seen on the L07J.Chakster, IMO, Dave got... 
what is Thomas Schick Tonearm effective mass?
Chakster, Without doing the math, I'd guess that 30g would be close, but "effective mass" is related to the distribution of the mass, as well as the absolute weight. (You probably can find many methods to calculate it on-line.) The (square of) the... 
Newb on the loose
"Upgrade the foundation first and your money will never be wasted. OTOH, upgrading the superstructure on an inadequate foundation is often so."I believe Harry Belafonte said it best: "House built on a cheap foundation will not standÂ… Oh no!" 
Who needs a MM cartridge type when we have MC?
Yep. I sent Peter a Grace Ruby with absolutely no cantilever at all, so in "re-tipping" he replaced suspension, cantilever, stylus. 
Kenwood L07D turntable and control unit
Once in a while you can find the L07J tonearm for sale on eBay or elsewhere. Unless you're lucky, that can take a year or so, but I do believe you'd find one eventually. I have never seen a Power Supply for sale separately. However, the schematic ... 
Solid core phono interconnect - Recommend Please
I am with Nandric, but if possible, eliminate the RCA (or DIN) plug at the tonearm end by directly soldering to the tonearm wires. The best "connector" is no connector.If you don't want to DIY, you might check on eBay. There was a guy who advertis... 
Fozgometer
If you use the Fozgometer, you should heed Fremer's latest blog and also the bulletins from the distributor. Turns out the Foz is very dependent for accuracy upon the exact DC voltage being put out by its "9V" battery. 9V batteries never put out e... 
Vintage DD turntables. Are we living dangerously?
Thanks, Sampsa. Have you compared your GT2000 to any other vintage DD turntables? Have you ever seen either the 18kg platter (hard to believe) or a GT2000X? 
Vintage DD turntables. Are we living dangerously?
My impression from touring Tokyo audio salons is that the GT2000 is much more commonly seen for sale these days than are some of the other TOTL vintage direct-drive turntables. This can only mean that many more of them were sold vs for example the... 
Azimuth question
I don't want to throw cold water on the Foz, but after reading the articles about the need to calibrate it and then noting that calibration is not exactly a simple matter, I am even more prone to stay away from it. Its accuracy depends upon the st... 
Vintage DD turntables. Are we living dangerously?
Fleib, I have seen a lot of GT2000s, both in person whilst in various Tokyo audio emporia and on the internet. The ones I have seen all seem to have a relatively "thick" platter, due to peripheral rim thickness more than anything else, but I don't... 
Vintage DD turntables. Are we living dangerously?
Dave, How much does the Resomat weigh, in comparison to the stainless steel platter sheet on the L07D? One of my reasons for not experimenting with the L07D, besides the fact that I adore its sound already, is the fact that the mass of the platter... 
Vintage DD turntables. Are we living dangerously?
In medicine, it is said that a "specialist" is someone who knows more and more about less and less, until he knows everything about nothing.Soft mats do have their appeal, but not soft rubber mats. Do you consider Delrin to be "soft"? I've never h...
