Found this for the IC107: https://www.ebay.co.uk/itm/M5220L-O...0ff820e:g:j6gAAOxy2CZTXk93&afsrc=1&rmvSB=true
thoughts on better sources ?

Mouser part number for D133HZ12-B2--exact replacement---> 771-NZX13A-133
I don't know... Good chance of it being fake.Found this for the IC107: https://www.ebay.co.uk/itm/M5220L-O...0ff820e:g:j6gAAOxy2CZTXk93&afsrc=1&rmvSB=true

Mouser part number for D133
You can try the diode first. NZX13B should be close enough. Replace D134 as well with the same.NZX13A is out of stock - will this work:
771-NZX13B,133
it's 13.1V instead of 12.9V
and about the IC107 - how likely is it hosed, could it be just the diode ?

Tech note: D159 500mw zener
HZ16 3L 16.3-17.1 volt 500mw

I think the D131 is also shot - this is HZ16-3L
might as well..HZ6C1L-- exact replacement ---> 771-NZX6V28.133 (Mouser P/N)
In circuit is misleading.Now ... am I doing this very wrong by testing the diodes in circuit ?
Lets measure all the voltages of IC107..
1.14.4v
2. 3.4v
3. 5.9v
4. 5.9v
5 -14.4
6. -6.0v
7. -6.0v
8. -4.0v
9. 14.4v
Disreguard... Guess what I found another typo in the schematic...Lets measure all the voltages of IC107..
1.14.4v
2. 3.4v
3. 5.9v
4. 5.9v
5 -14.4
6. -6.0v
7. -6.0v
8. -4.0v
9. 14.4v
Yes it is...I just got done verifying it on a parts unit I have not cannabized yet.Is a M5220L actually installed in the Yamaha?
