Philips Model 2262 MW / SW
Philips Model 2262 mw/sw. Customer repair. This set wasn't working when it was brought to me. On inspection there was wiring to the speaker and field coil that was without insulation as can be seen in the 5th picture, that was just the start. Once the chassis was removed, and in this set was rather difficult as the dial pointer mechanism and dial glass is separate from the chassis. In order to remove this chassis was also to remove the frame and dial glass. The dial glass had been glued to the bakelite but the glue had deteriorated and only part of it was still glued which was a worry trying to remove it without breaking it. Slowly and eventually it came away to my relief. The set was quite dusty as most are so with a blow down and cleaning with and old toothbrush removed the majority of the dust and dirt. Once the chassis was out I could inspect the under side of it and found that all the yellow insulation was cracked and badly dried out, after contacting the customer and receiving his approval to carry out the wiring repairs I had the tedious task of carrying out the work. After all the wiring repairs, new caps, plus new plug and lead and earthing the chassis I ramped up the voltage steadily, and at 180vac tunes started playing. When the full voltage was applied and the volume turned up slightly there was a burbly type distortion, even though the tubes tested fair to ok earlier on. The tube are as follows: 6U7G, EK2G, 6U7G, 6B6G, 6V6G AND A 5Y3G. The 2nd 6U7G the intermediate frequency amplifier seemed to be causing the problem, so after changing that it started sounding ok. Just to add the power transformer has been the coolest running one I have seen to date. The resistor R17 needed replacing as the Magic eye was not working after a new resistor it was dull but still working.
