Technics SL-1350
september 1974
1977
Following the may 1974 SL-1300, the SL-1350 is the same but in 6-disc changer mode.
The base and motor are reminiscent of the original SL-1200 which was under development around the same time, and so is, more distantly, the tonearm - the EPA-100 wasn't there yet.
The ultra-low-speed brushless DC motor needs only 0,1W to drive the platter but also actuates the tonearm's movements and changer functions with that ecological power !
Memo-Gram, the changer function & dial, allows to play and/or repeat up to 6 times 1 disc or go through 6 discs at once.
At least 6 sides because the SL-1350 wasn't a Sharp RP-X1 which is normal because the latter didn't exist et in 1974.
The gimbal-suspended tonearm has a long effective length of 23cm (for a changer !) and fairly low friction ratios ranging between 6g and 8g for both planes.
The base is the same as the original SL-1200 : one-piece diecast aluminium set on on high and rigid feet.
I believe the SL-1350 to have been available in black only while the original SL-1300 saw silver and black versions.
Gold-plated contacts and low-capacitance cables for CD-4 compatibility were and still are the audiophile touches set in the often clunky world of LP changers.
