Dating Technics SL1200's

This is mostly lifted from wikipedia's SL1200 page with some additions by KAB.
The serial number is generally found on a gray label located either on the back of the deck, or on the bottom.

Old-format serial number: NHOJF20765 (SL-1200 manufactured 1982) The first digit shows the year when the turntable was manufactured. These serial numbers contain no indication of the month of manufacture. It should be noted that serial numbers in this format contain no letters following digits.

New-format serial number: GE4FB001154 (SL-1200MK2 manufactured June 2004 or 1994) The first digit shows the year when the turntable was manufactured, while the month of manufacture is indicated by the letter following it. Months are coded as letters between A and L inclusive; A indicates January, B indicates February, and so on, so F indicates June. This was deviated in the last year of production where September production used the letter S for some reason instead of I. The way to tell if it was made in the 90's or the 2000's is to make 2 additional inspections:
1. Check the 3 screws that hold the motor stator, in the 90's these were fine pitch threads, later they were changed to hi speed self tapping threads.
2. Remove the platter and check for a cutout in the chassi in the 9:00 to 11:00 o'clock positions. This cutout also appeared in later models.
In 2009 the interconnect cable was changed to a high capacitance cable which can be identified by the end connector.

There are also at least two other serial number formats that were used by Technics on early SL1200MK2 models. "DA22 17D142" and "MJ7821F287" are examples of serial numbers seen on early production units that both lacked mounting provisions for the internal "bottom base" (Technics part # SFAU122-02) and possessed a different style of dust cover hinges. The old hinge had a receptacle on the back which received the hinge with a thin wide slot. The later and current models feature a hinge receptacle that accepts the hinge with a square opening approx 3/8" square.

In addition to the above, all the SL-1200MK2s from the 1970s and early 1980s have a 4-inch-diameter (100 mm) plate where the RCA and ground wires enter the chassis in the rubber base of the unit. The later models have a smaller hole through which the wires enter the unit. The larger hole size returned in 1997 in the MK4 and 2003 in the M5G models

Jeśli się nie boisz to odkręć zaznaczoną śrubkę i zrób jej fotkę .

Proponuję zdejmować headshell przy jakichkolwiek zabawach z gramofonem.

[sharan]

A coś się może popsuć ?

[Reymont]

Nie.

[sharan]

Trzeba mieć specjalny śrubokręt,żeby ja odkręcić

[Reymont]

Krzyżak chyba, tylko dopasowany jeśli nie chcesz pokaleczyć łebka.

[sharan]

Właśnie nie krzyżak,dziwny kształt ma tą główka tej sruby

[Reymont]

No to nie odkręcaj. W takim wypadku jest to raczej 2008.
Nawet na 100%. Lipiec 2008. Ładny egzemplarz.

A czy ten tekst można również odnieść do wersji 1210? Ja mam numer seryjny GE1AXOO1332.

[Bacek]

Raczej tak czyli 1991, 2001. 2011 raczej nie bo chyba produkcja zakończyła się w 2010.
