My uncle has same model, in working condition. I would like to listen that whenever I visit him next time.

Hi Vijay,

i would suggest that you need to bypass the amplifier and connect the turntable to a different phono amp, you may use the same speakers

the cables coming out of tonearm will go to the phone amp directly

Same model with forum member with same problem. We diagnosed it to one electrolytic cap before power amp and one BC547 transistor. That's all. Follow track after input selection switch. in preamp section if your power amp and PS is okay.

From my experience with vintage indian philips equipment, if the power supply unit, connectors, pots and wiring is ok, it can only be 2 things, 1) blown semiconductors, 2) blown electrolytic caps. You'd need some very basic knowledge of electronics to test these. Spare parts are readily available in the local market.

However, keep in mind that Philips used non-standard and more complex circuits in these pieces equipment (often adapted from the original Holland Philips equipment) and hence you are not likely to stuff that you'd recognize when trying to trace the wiring.

Nevertheless, its a good system to restore. If you were in Trivandrum, I would have been happy to help do it for you

Hi,

I had problems in sourcing a blown power transistor in the output stage of my Philips Hi Q International receiver in Allahabad and even in Delhi. Ultimately I had to go down to Lamington Road, Mumbai and spend over half the day in locating and collecting the item. I am not sure about the "ready availability" of spare parts in Bangalore. I hope it is so.

Regards.

Agree with Microflex, it is very difficult to search for older components, these days.

Dear Friend.

I doubt some transistors failed either in power amplifier or in preamplifier stage. In those players power transistors are darlington type. of course its is a very good player but not easy to repair without some electronics knowledge. I think it also has live line as common ground. Check where the actual problem , whether is preamp section or in power amp section.
