Philips FA960 – repair

Philips FA960 – came to me as broken. There was a try of repairing by someone else but with no success. Right channel played much worse than left one.



What was wrong?

  • STK3082III is in the place of original STK3102III
  • R732 – is burned
  • R734 – wrong replacement inserted, someone used 150ohm instead of 180ohm.



Amplifier has been cleaned – all switches and knobs –  and all electrolitycs capacitors has been measured – 24 of them need replacement. Here (->) the result of measuring main filtering capacitors – should have 6,8mF and after almost 30 years there is only 5,77mF 🙁 I have made also a modification from 220 -> 240V according to service manual guide.This Philips amplifier is a very near to Grundig A9000 and Marantz PM80. A big advantage of Philips is easy change to 240V what makes this one much safer in use. STK modules are very sensitive for voltage supply and life much longer in Philips.

All new capacitor are Nichicon Gold for Audio.
Below amplifier after repairing with new, original STK3102III.
Now amplifier plays like as new one – great 🙂
