I cant select all the speeds and the drive doesnt engage. Audio is good. What should I look for.

My experience with them is is not good & & they and a few others are a mechanical abomination, especially when compared to some of the BSR ones (which can also have: "Moments".

The biggest PIB is the grease soap which in many things dries out. Most turntables are supposed to be serviced every 500Hrs... Yeh! The dry soap acts as a glue. One does not mix grease, either by type or brand (CASA). Doing so can cause it to go solid & loose all lubricating properties: True, I have seen it.

It nearly always boils down to getting rid of every bit of dry grease soap and then replace it with new. Some of the motors have plain bearings & a felt oil wick. The type of grease is rarely specified, I use an "Inox" one which is conveniently in a tube, like a toothpaste one. I believe Philips (of course) used Royal Dutch Shell: Alvania 2. That may be superseded. We have been using Shell here from prior to 1926, when it was BIO Co. So if you do go that way, you can use the same wisecrack if it breaks: "Shell Shock".

Would I sparingly use degreaser?

A lot of that stuff has emulsifiers that not only act on the grease & oil, but make it miscible with water. So choose wisely. I just stand it sideways, ensuring that nothing gets at the motor & if really bad, a paintbrush & Kerosene (Avtur).

Paper towel, rag are also you friends.

Hi Carl, I've just done an RC-456 Collaro with the same prob;lem. Theres a sort of cam thingy underneath which acts on a cam follower which is about 1cm tall and cylindrical with a rounded top sitting directly under the cam thingy, now the cam thingy turns attached to a lever directly from the speed control. It is secured with a small nylock nut. Remove this nut and the circlip on the lever and the little spring above the nut and the cam thingy comes off out of the way. The cam follower sits on a shaft which goes through a slidy thing upon which the idler wheel is mounted. This slidy thingy should slide up and down the shaft with ease. So should the cam follower, which on mine was seized solid on the shaft. I sprayed servisol on mine and gently tapped it with a shifter until I managed to budge it then just worked it up and down until it freed up and then put it all together and everything worked as it should. Cheers JB.
