Sme 30/2

and the best thing, I hooked it up to the main system and just cranked it. since it's in the other room, no feedback! Who needs a Herzan???

That's a bonus! Guess it's about time for a Klaudio now.

Congratulations, Bruce. Koetsu and SME is a well known combination. Glad you have them playing well together. Are you planning on adjusting VTA for different LPs or just leaving it as set by Jazzdoc?

After seeing/hearing the system and jazzdoc working with it yesterday, it's definitely not in its final resting spot.
We started listening to some Stones and adjusting the VTA. The bass slam was really good, but when we started futzing with it, I didn't feel it was quite as good as what we first had heard. Then I remembered, to lower the arm, you have to apply gentle pressure to the top. So now I have the back about a half millimeter lower.
And no, I'm not going to get fanatical about changing VTA according to record thickness until I get more comfortable with how the cartridge sounds. Right now I'm running it at 1.92gm
I'm sure my mind will change once I get more comfortable with messing with a $15k cartridge and not pull a Rockitman!

I bought a second-hand limited version of the SME30 / 12A with SME V-12. Some questions have occurred when I debug this player. When I adjust the column gap to meet the gauge A terminal, press the 33 button, the speed is accurate and stable, but the light continues to flash and cannot be locked, and the upper board has obvious swing. But when I lowered about 1mm, this phenomenon disappeared and everything was normal . This phenomenon has not appeared in two states in 45 and 78, they can be locked quickly.

What could be the reason for this? And how to solve the problem?

Thanks

the specified column gap is not absolute just an approximation, but it’s good to meet the requirement.
first of all check if your stand is level. after that level the lower board then check if upper board levels while leaving exact gap on the columns to meet gauge A. if not consider changing suspension rubbers.
additionally the blinking light may indicates a horizontal misalignment of two boards or misplaced drive belt. check if drive belt is perfectly placed around insignificantly fat part of the motor pulley. check if motor is level too. if not align it with three screws under the motor. finally and most probably check if your belts is loose or oiled. for this purpose clean parts of small platter and pulley where the belt rides and wash the belt with plain soap (don’t use liquid soap). if the problem disappears after clean up cycle then getting a new belt is the way to go IMHO.
