Garrard 30 help please with automatic changer

Post by Mikfec » 17 Apr 2019 23:41

I've got a Garrard 30 on the bench. The client reported that the changer was not working and it turned out to be a seized mechanism. After lubricating, the TT works perfectly at 78rpm and 45 RPM but there seems to be too much drag for the motor to overcome at 33rpm. I thought the idler may have been slipping but it does not seem so. A very gentle push of the platter at the end of arm travel completes the cycle. I've noticed the spring (#94 in the pic) is hanging loose. Where does this attach? Is this the reason for the problems at 33RPM?

Your idler wheel may be in need of a rebuild. The AutoSlim mechanism changers I've seen on the bench all needed that done, and complete cleaning and lubrication of the proper type where necessary. After that was done, they ran fine.

thanks, that's where I was going because of the proper performance at higher speeds. I finally found an under-platter picture and see that #94 spring is not used on my model..

Still smells of old hardened grease to me. Did you clean before lubricating? Most likely culprit is old grease gumming up the cam follower in its channel under the cog wheel. NB - the velocity trip pawls must NOT be lubricated, but dry and moving freely.

yes, all the cleaning and lubing took it from frozen to 80% , I just added tension to the idler and all is well. Thanks for the help.

Does it have an audio cutout switch underneath? On an At6 I fixed up, the final thing to remove that sluggishness in part of the cycle, was to clean that. It was a blade that needed to slide between contacts, and it was sticky with old grease as well.

There's a tang this spring hooks on to. Look at the general service manuals here for pictorial evidence - diagram 18 may show the earlier mechanism version and the sliding long plate (record drop lever) is where this spring locates. the SL65 shows the revised method with open spring.

The large mech plate locates in the can via a stud sticking up through the deck plate. This stud MUST rotate freely and many don't!
