Up for sale speed calibration cassette for old cassette recorders and players. 99.9% of old players are suffering from playback/recording at a wrong speed after all those years. All you need is our tape and multimeter with frequency counter option hooked up to line or speaker output on either channel. Just adjust the speed adjustment pot to set the frequency as close to 3000 Hz as possible (pictured). You can use phone frequency counter app as well. Since the cassette is recorded at 0 dB you can adjust other playback parameters
playback level etc.) if needed. We use recently serviced top of the line 1979 quartz lock direct drive closed loop dual capstan Pioneer CT-F1250 and 1986 Pioneer CT-A9 cassette decks. Test signal would be recorded on side B only. Cassette brand and playback time varies, recently Maxell TDK D60/90 Type II. For better performance all cassettes are demagnetized prior to recording. We sell azimuth and combined adjustment cassettes as well. Cassette clear cases might have cracks or other imperfections due to age.
Included - used cassette with freshly recorded 3000 Hz test signal recorded at 0 dB level only for the duration of 10 minutes. None of the test equipment pictured (Pioneer decks, Oscilloscope, Fluke meter or cables) is included for sale, only one audio cassette of random brand/playback time type 1 (Normal) only. 
Please make sure that cassette mechanism was serviced and heads demagnetized prior to inserting the test cassette! This would extend test tape life.
We require payment in 2 business days. Shipping via USPS 1st class mail to US addresses only (non continental US shipping is more)! Normally ships the same business day providing the payment is made by noon EST and it's not holiday. Please feel free to ask any questions!
