I'm repairing a friends 30/60 and could use a schematic to find the value of a urned resistor.
Don't have it but one board picture and incomplete parts of the Crossmix150, which is somewhat similar.
Draw the schematic of what you have, including the missing resistor and might reasonably guess its value.
Is it in the power amp?
What transistors does it use?
High Teleman !!!
See you have the schematic of the 30/60 !!
Need it badly, 'cause, just repairing the first input jack--- two resistors broke--and I lost their specs !! I tried to redraw the schematic, but I never managed it to make the higher gain of the first input work correctly again.......seems it might work with a switch by inserting the plug and manipulating the second OP-Amp section ??????
Please, please, if you can and want, mail me the schematic 'cause as actual the two input stages sound identical and I miss the first channels sound !!

Dear flawie, Teleman does *not* have the schematic, re-read his post.
Try to redraw at least the input section and post it here.
Anyway based on what you say, you probably have a problem with the jacks internal switches or something like that.
That alone is enough to account for an important gain loss.
Or just send an email to Pignose and ask for it.
