I have taken a few moments out of packing to log onto my favorite web group.
My 701 cannot come close to my 1219. The electronic drive is constantly correcting its speed, while the 'ancient' drive system of the 1219 actually locks into line frequency. Some ears will hear the difference. Furthermore, both turntables share the same basic design of the auto mechanism. You might have misquoted Bill. The only function on the 701 that is not mechanically worked is speed selection.
Did you know that the 701 platter had to be redesigned to prevent more of them from warping? The 1st design platter was nothing more than a 1229 platter with the idler contact rim cut off. This is why it would warp. The newer platter has more meat.
Also, the motor did go through several design changes to improve reliability.
Still not as temperature-stabilized as the 721. The 701 speed does drift with temperature.
The arm on the 701 is very very, light, and how it works with a particular cartridge is variable. The higher-mass 1219 arm sounds great with nearly every cartridge.
To change the subject for a moment, has anyone here felt the weight of the 1019 arm? The outer dearing ring may be on ball bearings, but weighs like 1/2 pound. I have one in my spare parts bin, and find it quite amazing that any stylus can drag this across the arc of a record. But great does that turntable sound.
Well, back to packing. Moving is not easy for someone who has 57 years of stuff collected.
