Yamaha Stereo Receiver RX450 - UK Vintage Radio Repair and Restoration Discussion Forum

Hi.

I have acquired a Yamaha RX450 stereo receiver which I would like to get working.

Two faults that I know of are:

The screen does not light up (is this just replacement bulbs needed? If so how would i go about locating some compatible bulbs and how do I change them?)

Secondly, The knob has come out. I have the knob, how do I go about fixing it? and would I need a new spring?

Thanks for any help offered.

I can see five knobs on your receiver. You do not state which one, but there may well be a push in sprung steel section that grips the spindle.
