I’d try to find a domestic use rather than an ex radio station sample. The radio station ones often come with additional electronics (psu in 2 boxes) & speed (pitch) adjustment. They can sometimes be identified by the black inset cueing markers around the platter which helped DJ’s place the record in the right position prior to hitting Start.
I think there tends to be a degree of fear mongering about these decks by those who can service them but in my experience they are either working or not & if not avoid it & find one that does. I’ve a couple that I’ve had for about 13 years now & neither has missed a beat. On one the strobe light occasionally goes off but as the strobe markings stay still it serves no really useful purpose.
I took out the mechanism that brings the platter to a stop quickly (on one of them) but that probably wasn’t necessary.
Dave Cawley at Sound HiFi can service them but I’d need to be convinced mine weren’t working properly before throwing that money at either of them.
