Hi nandric, TTDD is Technics Temperature Defense Damper.  I'm not familiar with their other damper technologies as the only Technics cartridges of interest to me are those with the boron pipe cantilevers, all of which save one (AFAIK) use TTDD. As...

All Technics carts with TTDD suspensions are prone to this failure. When did Andy attempt repair of your 205CMK3 nandric?

SFTG172-01 was for the MK2A and MK3.  The latest equivalent is RGS0010A which is the thicker mat that was used on the SL-1200 MK3, MK4.  I've both here, and aside from the part number I can't see any difference. The MKII used SFTG102-01: http://fi...

lewm03-15-2016 12:10pmJP, can you amplify on your cryptic comment about the effect of a heavy platter mat? "Drive gain"?Okay, but I’m more than rusty on root locus and complex conjugates. :)My very hasty research this morning indicates rotational ...

I'll have my MK3 back on the bench in a week or two, time permitting.  If someone wants to lend a heavy platter mat to the cause, I can perform some measurements to try and determine the impact to motor performance. My intuition says it's less abo...

lewm03-14-2016 5:54pm2.7 kg!!!!!! (...) Perhaps Peter and JP can chime in on this subject. If you go to a show where Pass Labs have their source setup, you'll likely see a MKII with an ~8kg stainless steel platter.  My understanding is their 'tabl...

lewm03-10-2016 10:42amAcman, In principle, I want your BA Mat2. However, being a computer klutz, I cannot figure out how to contact you from this website...Very kind of you Lew, but it was offered to you, so if you want it you should get it. I hop...

lewm03-09-2016 4:43pmJP’s philosophy is if it’s not broken, don’t fix it.Let me add some color to that - my philosophy is if it’s not less than optimal, not prone to known reliability issues, etc. then don’t "fix" it. My MN6042 upgrade wasn’t born...
