Hi there
I wanted to get a CD640 in non-os, it works, with Tent XO to Xin of SAA7220(pin11) and WS, CL , DATA from 7210 to 1541
I want to use this player to try and test periferal gear to select the best Dac's, try Tent clock vs Kwak clock, try opamps, discrete or tube I/V's and maybe more.
But when i removed the 7220 (to test if without 7220 give less pollution on PS) the player plays 5 minutes, stops and cannot read disks anymore. After some power-down time it starts again and same story again: no reading of CDs
I have put the XO in pin19 of SAA7210, and disconnected the transistor with collector on pin 19 and emitter to Gnd. The base is connected by a cap to +5V supply and a diode to Gnd.(When this transistor stays connected to pin19, the XO will not be recognized, no CD reading and the CDM is spinning fast)
What connection have i overlooked? Has it something to do with master/slave function of 7210 and 7220? Or is EFAB the problem?
Thanks
