Re: Quad FM 4 tuner problems
I have an answer: the module is available and cheap to boot!
What Dada charged for it was simply rip-off. By the way, I bought a new transformer for my humming 405, and that was incredibly cheap too. Amazing service indeed.

Re: Quad FM 4 tuner problems
Update : the yellow buttons wouldn't trigger the TMS1000 at all, or erratically so. Sometimes one button would work, just like that, and one moment later it would do nothing.
I realized that when I touched pins 2 and 3 with my finger, looking for bad solder joints, everything worked as it should. New joints did nothing, unfortunately. Then I tried to spray a little contact cleaner over those pins and it worked fine until the liquid evaporated. I connected small caps (330 pF) between pin two and GND and pin 3 and GND. Now, stations can be selected and memorized fine as they should. Explanation please? |
