Linn LP12 Transcription Repair

Thanks for the input all...nice analysis. Just kind of sensitive since it’s the first time it has been cracked in 18-20 or so years. Not bad I guess.

This is something that I hear about with some turntables. I can't say that is your issue for sure; however, when a turntable motor starts up, it sometimes takes a second or two for the motor speed to stabilize. It is possible that the motor gets going, the platter accelerates, the inertia of the platter, as it accelerates to speed, actually causes it to rotate a tiny bit faster than the proper speed. The motor then stabilizes, the belt grabs the platter and slows it down to proper rotation speed, which is what the shudder may be. It's all over in a few seconds. So if your table is a fine a few seconds after this initial start up, I wouldn't worry.

Seems to play fine...probably being picky.

Any ideas in the isolation matt area for something inexpensive?

I imagine if the LP12 runs normally once it's started up that it's OK.

If I had to guess, it's more likely to be a suspension issue. The tuning of the springs might have been changed by the shop.
