Maybe you should try putting a smaller (in Watts) lamp in the pop light...

SOURCE: TECHNICS SL-B280 DUST COVER W/ HINGES

All parts are discontinued for this model. The SL1200MK2 dust cover will not fit this turntable. You can actually have a dust cover made rather simply and cheaply (depending on where you live). Just take the dimensions to a PLEXIGLASS or even a GLASS shop. You can even purchase the Plexiglass yourself, cut it, and glue it together. I would suggest getting it professionally done. You can use any high impact plexiglass. Get something that is resistant to scratches and discoloring.

There seems to be 2 issues with this unit. Usually when the platter speeds up very quickly, one of the IC (integrated circuits) are faulty and needs to be replaced. However, I've never seen the 33/45 lights come on in addition. So, perhaps the issue started with faulty 33/45 switches, and it then caused a short to one of the IC's.

This will have to be professionally serviced, as it is not an easy fix. There are various circuits on the main board which control the drive, so it's a matter of diagnosing which is the culprit. The 33/45 switches will also need to be tested/replaced.

The part is located HERE - but you will have to take apart your turntable from the bottom in order to replace it. It's not very hard, but if your not mechanically inclined, I would not suggest doing it, as you could cause more damage.

either the cartridge is bad in the phonograph tone arm.  Or the pre-amp in the stereo is bad...remember that the turntable is the only accessory that uses the pre-amp input on the stereo.  I'm betting the pre-amp is bad.
