Miracle by Joseph long on Dynavector XX2MKII cartridge

Lewm, I'm glad I gave you something humorous to give you a chuckle. I have to stop and laugh at myself now and again these days being this age, and having had a stroke, I'm glad I can still remember my own name. Most of my life, I was very good at spelling and remembering words and how to use them. I feel lucky I was able to get the Dynavector mounted and aligned, and I'm grateful that it sounds so very good, I don't know what kind of earth-moving equipment Kometsu makes (they probably don't either).

I'm pretty sure it will be the last cartridge I will ever set up. I heard back from Joseph, he reminded me of the high purity halogen-free silver-plated copper wire coils he used during the rebuild. Yes Koetsu is what I meant to say, getting old has it's drawbacks, you know?

Regards,

Dan

Hello Lewm,

I heard from Joseph twice, first was: Nude 3/80 micron Orbray microridge.

Second was a long missive:

If I may interject some information: Your cartridge had a broken suspension wire which necessitated a full rebuild. If all it needed was  a new cantilever or diamond, I would have used an original exact replacement Ogura r/R70/30 uM (micron) Vital Line contact diamond, but to save time and expense , I used an extremely high quality Orbray (formerly Naniki) suspension block/tie wire/coil frame/cantilever subassembly.

The coil frame on this unit is thinner than the original Dynavector unit so there will be a savings of moving mass with improved tracking ability. I could have rebuilt it using the original and knew everything else, but this takes a very long time and adds unnecessary expense to the repair.

The frame has no wire on it, so I wound by hand new coils ~50 AWG halogen free high-purity silver-plated oxygen-free copper coils 50 turns per channel with a resulting internal impedence matched to 7 ohms. Original spec is 6 ohms  so pretty  close Output is adequate , I estimate 0.3 to 0.35 mV to the original rated .28 mV. The diamond that comes on the subassembly is a nude r/R 3/80 Orbray Micro Ridge, that is 0.1x0.1 mm square and 0.3 mm tall. It is lower mass than the original diamond and an extended line contact of the PF. The lower mass will impart a more delicate nuanced quality that the larger Ougra and also pick up more detail due to much finer scanning edge spec'd to to be anywhere between 2 and 3 um by the manufacturer.

I reused your original elastomer suspension because it was in excellent condition. 

I hope you don't mind me coming in and filling in these details. You have been an absolute pleasure to work with, so polite, nice, enthusiastic, patient, and charming.

I certainly hope this will not be the last cartridge you will ever mount.

Thanks for being you, and God bless.

Joseph 

So, lewm, I hope this answers the questions you were wondering about.

Joseph,

I was going to email you and let you know I posted your explanation, but I see that isn't necessary, you didn't say anything, so I guess it's all right.

I appreciate your explanation, but I found out what I needed to know as soon as I played the cartridge, my appreciation just let me know all I needed to know.

Thanks, and best regards,

Dan
