Description
LONG UNAVAILABLE AND EXTREMLY RARE, THE SHURE TTR109 TEST RECORD FOR LEVEL AND CROSSTALK WAS A PROFESSIONAL TEST DISK. THIS TESTS BOTH 33 1/3 AND 45 RPM . STROBES FOR BOTH 50 HZ AND 60 HZ ELECTRICAL SYSTEMS.
ACCORDING TO THE SHURE SERVICE SITE: The TTR-109 was designed to test output level and channel crosstalk. Both sides of the 33 1/3 RPM LP record were the same. It was not a consumer test record.
Sine wave signals were recorded at 1kHz with a 5cm/second peak velocity. The record bands alternated between left and right channel recordings. The record label had a strobe pattern for setting turntable speed. A cardboard overlay of the strobe pattern for 50 Hz use was included.
Regarding condition: UNLESS STATED ABOVE, ALL ARE SIGHT-GRADED ONLY. I am not a professional record-grader. I never say a record is “MINT” unless it is sealed. If I state “Near-Mint”, it is visually about as perfect as I can expect a used record to be. It may have minor marks that do not impact playability. My idea of that may be different from yours. For most opened/used records, I use “Very Good” (VG) or “Good” (G). I don’t sell records that I consider less than “Good” condition unless a record is special and has some value beyond the playability of the vinyl itself. Then I will use “Fair”. You will want to clean any records you buy! I clean all of my records but these are very old, used records and may have deeply-embedded dirt that requires multiple cleanings. I am as honest as I can be. Please do not buy records from me if you have any reservations about the condition. Please examine the pictures carefully. Ask all questions before you bid or buy. Thanks
