Test record question

[DanHello]

Hello,
I have just stumbled upon a copy of the Project 3 Popular Science test record made in 1967. I was wondering if anyone has used one of these particular test records to adjust anti skate. It has sections for channel identification, channel balance, test frequencies, etc. I am not sure which one to use and how to do it. Any input would be appreciated. Thanks!!!

No I don't, but I'm concerned about the condition of your find and how that variable will influence test results.

Being a Pop Sci product and not one of the "audio only" Stereo Review, High Fidelity , Audio , or others product, circulation may not be all that grate. does it have user instructions with it?

You must look for a section witch contain signals with 1000 cycles/second, if this is distorted you must set a higher VTF and anti-skating for equal sounding speakers, If you can play that perfectly, you have a nice cartridge:thmbsp:

I think my test record is a different brand, but the anti-skate test should be the same. It will be a track with no grooves. You simply set the tonearm down in the empty space of that track, and adjust your anti-skate until the stylus seems to just "float" on the record - not moving towards the outer part of the record, and not moving towards the inner grooves.

I usually use the anti-skate test after I perform the "trackablility" test (if your record has one). It's the track with four or five little sections of tones - each getting progressively more intense. After setting a tracking weight that allows me to pass that test successfully, I then move on to the anti-skate test, and make adjustments there, if needed.

If I'm feeling real anal about it, I'll repeat the whole process until I'm sure both trackablilty and anti-skate tests are a success at the same setting for tracking weight and anti-skate.

The older test records do not have grooveless section, [like mine] it have the 1000hz signal, and also the section with 4 signals you said, in my situation the 1000 hz help me to set both[VTF and anti-skating in the same time] if this setting it's correct the 4 signals section will perform clean.

Thanks - that's great info.! :thmbsp:

You must becareful not to set VTF higher than recomandations of the cartridge, anyway that test it's a little exagerated and not must be played perfectly, if you can play all of this with clear sound it means your cartridge is the best. Good luck:thmbsp:
