Re: RX2 Turntable - is the speed adjustable, and if so, how?

When I was a lad you used to be able to buy a paper strobe disc (a disc with a multitude of radial lines) which, when illuminated by a conventional 50Hz incandescant light (if you had access to a real laboratory stroboscope even better), the lines would appear stationary if the speed was correct.

Theres an free app here to print a strobe disc (with selectable frequency and deck speed) - 3/4 way down the page called STROBE.EXE. It might be worth a go (make sure there's also a record of the deck so the weight and inertia will be correct and printing on light card will be more substantial than paper).

It is possible - there are two variable resistors - one for the 33 speed and one for the 45. I believe if you look at the base of the RX2, there are two small holes and they may even have the speed markings by the, They are situated in a position under the arm at rest.

however if the speed is slowing, consider whether the deck needs servicing - lubrication and cleaning and probably a new belt are in order. The service manual is on site if you feel adventurous!!

RX2 Turntable - is the speed adjustable, and if so, how?

Hello...I've been enjoying my RX2 now for about 7 years and I'm wondering if, over time, the speed of the turntable needs to be calibrated. It's seems that it's just a hair's breadth slower than it should be, and since everything is automatic with it, adjusting the speed seems like it would be difficult to do. So my questions are:

1) How can you tell if it's rotating at the proper speed? (There's a quasi-geometric pattern on the platter which I wonder if it's not intended as a way of guaging the speed).

2) How can I adjust the speed, if it is, in fact, rotating slower than it should be?

Thanks for any help/advice.
