Re: Midland hello
- It sounds like you might have a frozen bearing. They were usually
bronze with lithium grease or oil for lubrication.
A lot of console manufacturers used Garrard turntables and they were
considered the best. It's a lot easier to find parts for them and the
changer types are available for little or no money.
If you deceide you want to put in a "superior engine", post it here.
I have a friend who goes to all the estate sales and if he buys a
console for th espeqakers and amps, he just throws them away. I am
sure the DAC members can help you out.
Whenever I work on vintage audio equipment I always wear a white shop
coat, like a doctors, to get me in the proper frame of mind. It helps
reduce the impulse reach for a hammer.
