Difference among Denon turntable plinths DK100, DK100G, DK100F, DK200, and DK300?
Look for examples of each on Yahoo Buyee in Japan. Best I could see is that the DK100 series uses a long armboard and is a lighter colored veneer, DK200 series uses a smaller circular arm mount and the DK300 series is like the DK100 but in a dark ... 
Bottleneck Headphone Amp Repair
Since it was built as a kit he is very familiar with it. Open it up and very closely examine all parts for heat related stress, maybe a bad tube was drawing to much current. Also check every solder connection, even reflow them, especially if this ... 
Best modern 6550 tube for ARC per-amp
Wow, it's a regulator in the power supply, helps keep the B+ at a constant voltage. Music doesn't pass through the power supply at all. That happens at the output stage. If the music is modulating the power supply than the power supply is sagging ... 
Are Jelco SA-750D and SA-750E swappable?
If your using armboards and the armboard is able to be swapped in and out in the EXACT same location than you can swap tonearms with the armboards and preserve your setup adjustments. Tonearms with different spindle to pivot differences will not m... 
Having A Tough Time Justifying More Than One Table
Elliott is the person that inspired me to build a Victor based TT. I to have a CL2P plinth with the two arm boards but I'm using the TT 71 motor drive instead. I wanted the ability to try multiple tonearms so being a machinist I made new armboards... 
Tone arm holes do not line up - best way to attach TT?
Yes, something is not right. The spindle to pivot distance can be drawn as a complete circle around the platter and anywhere on that line is ok to mount the tonearm pivot. Of course most locations will present other issues. But if it is drawn at t... 
Tone arm holes do not line up - best way to attach TT?
The tonearm must be mounted so that it has a fixed relationship between the TT spindle and the the tonearm pivot and that relationship should be very ridged. Any movement between the two points will be read as a signal being generated in the cartr... 
Reel to Reel information, user tips and tricks...
Elliott Newcomb on here is a serious tape guy. I had a chance to listen to his rig and it was awesome. He will chime in eventually. BTW, nothing to laugh about with tape, it's what everything was mastered on till digital came along. Digital is jus... 
Audio Research or Macintosh?
Early ARC tube amps had little protection and gave them a reputation that is still around but totally unfounded today. I think you made a nice choice with the VSi75.BillWojo 
Vintage equipment sounds awesome
I hear you. I have a Victor TT 71 drive in a Victor CL-2P plinth with two tonearms, Audio research SP8MKII, McIntosh MC40 monoblocks and Altec Valencias. I couldn't be happier. It would take a lot of money to beat this system.BillWojo 
The PCB motor might - Tech which might actually make it to us
Actually, it looks like a coreless DD motor design brought to us by Dual back in the 70's? Dual invented the cogless DD motor that everyone copied. Making the coils on a PCB is nothing new either.BillWojo 
To upgrade/repair or not...Thorens TD165
Why don't you clean and lube it, give it a go before rewiring it? New belt is a no brainer, just get a high quality one or the speed will be off. I think Thatcher in Germany sells them.Do you know what tonearm is on it?BillWojo 
Sleeper Vintage Receivers, AMps, Tuners, TTs,etc..
JVC turntables for the Japanese and European markets were called Victor. The high end offerings were some of the best DD turntables ever made. They also made their own tonearms that are highly coveted today as well. Victor was an engineering compa... 
the dreaded breaking of tonearm wire...now what?
tpsonic said"If you are going to rewire ,I suggest a 24ga or greater solid core wire> 30-35ga would be best/sliver?" Never use solid core wire for a tonearm cable. It will mess with the free motion of the arm and all the bending will make it sh... 
Tube advice
ARC's earlier tube amplifiers had a deserved reputation for tube failures and collateral damage that was fixed in later models. There is a great post over on AK about a D115 that Dave G acquired as a sort of "kit" and built to ARC’s specs. As buil...
