I have one of these appears to work perfectly ❤

Test mode is an unique concept..

excellent but as switches you should get Omron B3F-1020 - 1N force or B3F-1022 - 1,5N Force, I’m using B3F-1xxx Omron series as replacements as there are very good, cheap and made in Japan. i see this what you install are hard to push with lots of push force. Get omron's and you’ll be happy with result, will be as original.

i hate that new micro switches...they are so noisy. The GX-9 it`s a great recoder on Basf tapes too. Nice work!

What you did is good, but i belive there should be some test points wich must measure a certain voltage, and you should adjust the pots based on the voltage target.

Manual is complicated for that, it requires to use external generators and measure AC voltage on test points. I tried, it did not work for me as described. Maybe I did not get it right, but my way works just fine :)

@@hifirulezzz I ve calibrated decks that required injecting frequencies at certain points and it does get very confusing sometimes. Easiest method is what you did and it s nothing wrong about it.
