    Yamaha CT-600 Electrolytic Caps

    Electrolytic caps in the power supply and function board all measure greater than 20% over or under value. The exception is the 3.3uF caps, they measure per spec. These are all easy enough to replace, but my concern is the Tuner Board is also loaded with electrolytic caps, if I start pulling...

    Tuner alignment gear question, for Pioneer Tuners

    Question for those of you who do Pioneer FM tuner alignments. What equipment do you use? Is it modern gear, or vintage? If you can/will, quote what you paid for it and when. Did you repair the test equipment before you used it? How often or how many have you done? I am thinking about doing...

    First attempt at FM alignment

    I have a Technics SA5400X receiver that I got for parts and just completed its restoration. The tuner seems to be working, although reception is quite weak, it only picks very few stations and it is pretty noisy. I therefore decided to use it to try my first ever alignment. I currently do not...
