Vintage DD turntables. Are we living dangerously?
I'm working on a complete restore of a TT-101 too, should hopefully have it up and running in a week or so.Lewm,  I have found suitable replacements for most of the transistors in the TT-101, some of the original ones have the silver plated leads ...

Phono pre "Break-In" process? Necessary?
Agree with break-in period on electronics, however its quite short IMO. I find that length of period on, i.e. the circuit is fully thermally stabilized have a much greater effect on sound quality than any "break-in" have. Speakers have a much more...

Xor or single ended?
Its generally not recommendable to hook up a fully balanced phono system with  RCA connectors because the negative node is thereby fully exposed on the barrel of the RCA connector i.e. not shielded,  this can have severely negative effects.  Most ... 
Ortofon bronze PNP ALERT!!!!!
Paraneer, FWIW, I'm by no means "disgruntled" with Ortofon, they remain one of my favorite cartridge choices, I recommend and sell them frequently.  That I had one mishap with a cartridge, where I do think that the specific design of the connectio... 
Vintage DD turntables. Are we living dangerously?
Got my Victor TT101 today, which have some speed issues - knew this when I bought it, so no surprise there.  My initial impression is that its overly complex, especially compared the the Technics SP10MK2 and MK3, which I both own too, and have ref... 
Ortofon bronze PNP ALERT!!!!!
This unfortunately happened to me too with a Ortofon 2M Black a while back, one of the connection pins pulled right out of the body when removing the leads.  I agree that this should not happen - the pins clearly should have some retaining feature... 
Velodyne studio monitors??
Velodyne made Monitors in the mid 90's, it was a short stint, they got a pretty bad write up in Stereophile and quickly there after went back to making only Subwoofers.http://www.stereophile.com/content/velodyne-df-661-loudspeaker#3agsTZQdrAyYGsxx...

Az,We make custom ones any size you'd like, typically 2 x 2 welded steel piping, sand filled,  then a hardwood plate typically 2" thick mounted to that frame with compressor vibration dampers, works like a charm.You can check my systems page for h...
