VAS (Steven Leung) cartridge repair/retipping service?

@Vasaudio; I see in this thread that you have convert  a Denon 103 to mono cartridges.  I have a Grado Master Reference cartridge with one dead channel, I wonder if that could be converted into a mono cartridge. Would it be a good move cost wise?

Upgrade report:
VAS Steve upgraded VPI scout master motor, JM9 inner wiring in arm and junction box, new VAS Nova 0.4 mv version.

The surface noise is zero to none. Very very quiet. Cymbal sounds very fast, clean, real, detail, like real metal to my ear. Cello sounds woody, powerful, deep, and focus. Vocal voices are very realistic, relax, thick, and present. Channel separation and image is wide, accurate, and 3 dimensional. 

Huge thumbs up for Steven!

I sent him a Koetsu Black Goldline that only played on one channel.

He diagnosed broken coil wire and repaired same and returned to me all within 3 weeks.
I thought price was fair and it now is playing on my 401 like a good un!

FWIW, How would an issue like a broken coil wire occur?

I just got my Benz L2 back after Steve replaced a bad coil and the old stylus.  I don't remember it ever sounding as good as it sounds now.  Highly recommended.

Slaw, use your imagination.  Maybe being mishandled or dropped, for instance?
