Trident Fleximix channels fusing resistors

Hi all,
I have a 12:2 Trident fleximix here, with only 8 input channels working. The others have burned fusing resistors (r19 and r29). There were several issues of the channel strips. Issue1 had 33ohm fusing resistors (as has been confirmed by posts of Jim Williams on other sites). Issue2 has 75 and 150 ohm fusing resistors, as shown in the schematics floating on the internet. I have issue3, with what seem to be 120/220 ohm resistors. Can anyone confirm the values of these issue3 resistors or even better yet, provide me with schematics of the Issue3 channel strips?
The fleximix has a strange 40v power supply and I probably should change to an external +/-16v psu but before I start doing that I want to be sure all channels are working as they should.

Thanks in advance!
Bram

so your looking for revision 3 schematics because you have a fault where 4 channels do not work out of your 12 channel console?

Yes! My console has issue3 channel strips and I have only been able to find schematics of issue2. Thanks for the clarification!
