Vintage DD turntables. Are we living dangerously?
These days I work on audio stuff at our house in Brookfield, now relegated to weekends.  I like your version better! 
Vintage DD turntables. Are we living dangerously?
Hi Lew, I don't have any pictures of yours that show the finish, but I thought it was painted.  I've had a couple TT-101 through here since yours.  This one seemed like a nice candidate for refurb.  I'm not sure what its disposition will be as I'v... 
Technics Sp-10 platter screws
Never seen washers on the platter screws for a MKII or MK2A.  Service manual diagrams and parts lists don't call them out, and my NOS MK2A that doesn't have any in the factory sealed hardware bag.

Hi Halcro,Not NOS, but rather good shape considering.  The main bearing in this one is in spectacular shape - extraordinarily smooth. Yes, we're talking about the same area.  The exposed bit is brushed, and the inside bit is unprepped.  The full p...

Hi Halcro, The top on this one isn't painted like most - it's brushed and anodized.  The discoloration you see is what the raw casting looks like. http://fidelisanalog.com/wp-content/uploads/sites/3/2016/11/IMG_2102.jpg 
Technics EPA-250 Cartridge Matching Concerns
16, but one is a partial I bought for parts to fix two others.  I've two bases as well.  Fantastic system.

Careful Lew - that's what I said 15 armwands ago!

Yes, the aux weight that came with the EPA-A250 is identical to the aux weight for the SL-1200MK2, et al.

norm, Are you certain the Elgar unit is working correctly?  I see that it's advertised as having sine output.  I'd try a simple step-down as a sanity-check, à la https://amzn.com/B000WMK6QY.According to the literature the transformer in the 101 is... 
Yamaha GT 2000 Turntable
Raul, A bit apples and oranges there.  The GT-2000 spec of 0.005% W&F (note no standard mentioned) was measured at the frequency generator, while the SP-10 MK3 spec of 0.015% JIS was measured using a test record.  I've only one test record out... 
What is Technics thinking?
My GAE is being help up in export customs from Japan.   
Technics EPA 100P - Tonearm
nandric, It's an accessory counter weight with an auxiliary weight for the EPA-100.  I believe you can balance an SPU with it, not that I'd take it to that extreme.  I have one, but have yet to use it or compare it to the stock weight. http://www.... 
Technics EPA 100P - Tonearm
Nandric,An SH-100G1 should do the trick.  
Vintage DD turntables. Are we living dangerously?
Hi Norm,Neither is normal.  The hum could be high load on the PT due to bad filter caps in the PSU.  The speed issue may be a consequence, or there could be other causes. A recap isn't a fix-all though - it will need calibration afterwards, and th... 
Who needs a MM cartridge type when we have MC?
Yes, though with a rubber donut I'm not much bothered by pesky details such as intent and premeditation.
