hi herbert,

unfortunetelly, all components you mention are unmarked. even when are new, capaciors are unmarked, are labeled only on the package strip. you have to find an service manual - I'm looking also for one. maybe will appears somewhere. I found only for M13, but is not usefull for M5.

but how you get so many deffective components?

This may be an easier and even cheaper solution (especially if you value your time at all):

you'd probably have to call during the day and get the service manager for any chance of figuring that out: http://line6.com/company/contact/

more than likely they'd have the whole boards available for nearly the replacement price...

although it never hurts to ask.

I have a M5 with same problems - no sound come out, excepts when is used in True By Pass mode, but only when the button ON/OFF is OFF - getting only the original DRY guitar sound bypassed. So, no effects comes out, no wet signal! when the mode is in DSP, nothing comes out.

The pedal is not mine, I got it only for repair. The owner used with an 12V supply and after that attempt, the M5 was damaged.

Also the tuner doesn't work, but I fixed that replacing one of the TL072C opamp from the motherboard.

Seems that internal buffers don;t works - I don't have schematics to be sure where are located. I didn't find the wet signal trace either. otherwise voltages are very clear marked on the PCB, I measured and are fine.

I will apreciate if I get an service manual or some tech advices. I received the pedal yesterday, but now I'm stucked on it.

Regards,

Sorin
