Back to vinyl – Part 2.
I decided to go DIY way. I built quite few audio things in my life. Back in Russia I built several pairs of speakers from the ground up, which to be honest sounded like you know what. Later I realized that when I used drivers from actual speaker manufacturers the results were much better. I shall not mention power amps and all sorts of tweaks – they don’t count if you have a PhD in electronics.
So I decided to approach this as an engineer.
What is a turntable anyway?
Tonearm part is easy – though some people get exotic and build them, there is no need for that. Second hand market in the US is not as extensive as it is in good old Europe, but it does exist and one could buy a very decent arm for very little money.
Plinth (if any) has to be acoustically inert. Big deal! I live in New Jersey, kitchen remodellers are probably as common here as lawyers and realtors, no shortage of Korian and granite of any shape, form and color (I tried to write “colour” but my US edition word processor stopped me).
Motor – well, not that difficult. Very high quality 32 pole DC motor with adjustable power supply would cost you a mere 5-6 hundred bucks (and don’t listen to that BS you hear at CES!).
Bearing can be special-ordered from any reasonably good machine shop. Depending on the quality and materials it would cost anywhere from $10 for a decent one to $500 for something out of this world.
Platter can be made in the same machine shop using any material you want and the cost would be so low that is not even worth mentioning. If you are fan of acrylic, try calling a place that makes it and get a quote. You’ll never be able to look at one German turntable company without a smile…
I was almost ready to start ordering components when accidentally run across… Technics SP10MK3! Not Mark 2, but legendary Mark 3! The one that lots of people are talking about but almost no one actually saw!
I bought it from a guy in Australia for an incredibly small amount of money. Even with shipping it was still much less that you could expect paying for a piece if History.
I inspected it thoroughly when it arrived. It seemed to be in almost perfect condition, small scratches here and there, turning on and off, changing speed (and adjusting it).
I ordered a service manual for it and began working on a plinth and tonearm. Korian plinth with space for 3 (three!) armboards - 12” SME arm for my dear Kontrapunkt B, RB600 for Exact that I use as a test platform and one extra space for heavy arm with Grado Statement that plays female voices like no other cartridge I ever tried.
Is this Heaven or what?
Well, it was Hell. Two months into the project everything was assembled. Amplifier was warm, phono corrector just retubed with NOS Telefunkens, one of the last Frank Sinatra’s albums was ready to go out of the shelf when I heard terrible squeaking noise from the table that I turned on and that was spinning at exactly 33 1/3 RPM for the last hour…
The motor was gone. After I took it apart I realized that the table was probably very heavily used and before selling the owner put some really thick oil into its bearings so after you turn it on it would not be apparent that it is completely worn.
I tried to find new motor with no results and the quotes from machine shops to rebuild the motor were so high that it did not make any sense to try to resurrect it.
I sold SP10 in pieces and actually even made couple hundred vs. what I spend on it (including shipping from Oz), but once again I did not have a table!
And I called Kevin again…
To be continured…
P.S. The reason why I did not mention any names in Part 1 was not political correctness. Coming from the former Soviet Union I am as far from being politically correct as it gets. I was just trying to be nice to people that own those tables and like them!
