But I can“t read what is written underneath.
Thanks! This confirms that I can still trust my eyes :lol: It's quite hard to be sure about colors if picture is not focused on the subject.

Thanks! According to https://coil32.net/online-calculators/i ... lator.html "LD01" seems to be 10uH coil.
They indeed look like caps: https://www.partco.fi/en/electronic-com ... p-10u.html :cheers:

While we're at the topic of TT, I also need U203 component which is crystal oscillator. It seems to be nearly impossible to acquire 32.215905MHz version, but my local electronic shop has 32.256MHz flavors in stock. Any opinions about it? Is difference too much for TT to handle?

I think you cracked it. Now thinking about it, I should've figured it out. The schematic has a IND01, which is a 10uH inductor right next to the CD11 and CD12 caps. Good job!
