Luckily I can read German and donor machines could also be a Sony TC 440 and Sony TC 580 which have the same chip.# l1 N9 R: Z6 A5 r8 K
A rare Sony turntable TTS 400 has the same chip used as well.# [/ r, V2 { n( m. R0 K% y

I got some of my Dutch R2R friends to have a look at it as well and with a bit of luck they can design a circuit with disrete components.
