Thanks for a great website

Just starting cruising this site. Wonderful information. I grew up with vinyl, starting with my mother's old mono record player then her eventual purchase of a hi-fi system. I own multiple computers, printers, and every gadget that can interface with those. I have gone through the 8-track stage then on to tapes gradually evolving into cd's, mp3, and internet radio. However, I still love the technology that is the subject of this site and I find myself drifting back into the bygone era of vinyl. I currently have a Pioneer Direct Drive PL-200 and a Dual 1218. Both are still running well. Great job and keep up the awesome work.

Hi, downloaded the strobe, enlarged to 110%,put part of a file folder against it to stiffen, cut an equal cross in the center, popped it on the spindle, got a reading, but it was very faint, took awhile for my eyes to pick it up but it worked. Tested it on a TT withe strobe tester on the platter. so alls well..

PDF Downloads on strobe disks and protractors

Great site. If one is going to print from one of the PDF files I have noticed that when opened they are set at 97.3 % that shows on them or, if they should be altered to 100% before printing? If anyone could advise me I would be grateful.

Scale

Hi,
Unlike protractors, the strobe discs can be printed out any size without affecting accuracy.

Hello, really nice site.

Hello, really nice site. Also full of remarkable articles around here. One single question, how do I know the correct frequency to our own country?

Correct Frequency for your country

Hi abshandra to find your frequency look on the back of your electrical items like your TV or Microwave oven the number you want will be on there next to a little sine wave.

Voltage and frequency by country

This list on the web provides the voltage and frequency (along with a picture of the outlet) for all countries: ElectricalOutlet.org: Receptacles, Outlets, Plugs, Adapter Plugs

This is great! Have been trying to locate a strobe light to check speed on a B&O turntable. Found one on Ebay for ~60. This took 5 min. to print and check my tt speed. Thanks so much

Careful of the fluorescent lamp recommendation. Newer high efficiency electronic ballasts rectify line current then generate a ~10kHz signal to the lamp.

The 10KHz sounded interesting, so I experimented. I used a Lights of America compact fluorescent spiral bulb #2432-S as the only light source in the room. I also tried a GE Helical #FLE26HT3/2/D bulb. The strobe disc worked perfectly with either one.

60hz 33⅓ / 45rpm strobe disc

Fluorescent lamps work better, they turn completely on/off at 60 hz. I appreciated the "full size" comment, having printed out a cartridge alignment protractor LESS than full size.

Amused by instruction 2. It doesn't matter what size you print it out!

Strobe Discs

Any chance somebody has a pdf to make a strobe disc for 78 rpm ?

78 RPM strobe

Yo Grufflybear:

I saw your post and I just submitted one to VE last week, but they haven't put it on the website yet. Didn't realize that there was not a 78 strobe on the site, because with this strobe I never needed to look one up. It's a nice 78-45-33-16 diagnostic strobe for 60 hz that reads the actual speed and plus and minus 2% and 4%. About 8 inches in diameter. Easy to read. Two speeds per scan. Give me your email in a PM and I'll send you a scan, or you can wait till VE gets it posted.

Good luck from the old (strobe) flasher.
