Garrard 401 service & tweaking my new project.

Great, thanks mangos & islandman! That's more than helpful! For some reason ~ in my research I learned that when switching from 220v to 110v the idler wheel also had to be changed. Is that not true?

Phduncanson,

First, I would like to thank Chris for his superb job of describing the switchover in voltage. Although I have done it (once, several years ago now), my memory these days is for the birds.

As for the speed, the idler wheel remains the same. What changes is the hub that is driven directly by the motor. The pulley sizes are different from 50hz to 60hz.

The 60hz pulleys can be purchased, as I previously mentioned, at PerfectSound, in the UK.

The strobe markings will be incorrect, as they are for 50hz. That is a small concern, though. There are some 60hz platters out there, but they are quite rare, and expensive. If you decide to go whole hog and replace your platter with a copper or stainless steel one (extremely expensive!), the strobe markings become a moot point anyway.

By the way, I am not in any way a schill, but I can recommend Woodsong Audio, as I've dealt with Chris, and found him very good to do business with.

Enjoy the process, I know you will enjoy the result.

Regards,
Dan

Ok, so I need a 60hz pulley and a 60hz platter. Ok. Very helpful again~

A new 60hz pulley and a 50 hz strobe will work fine. You do not need a new platter. Loricraft used to sell a 50hz strobe, I think they still do.

Word! That's what I'm talking about mangos! Thanks the more ~
