Capacitor identification in Hughes and Kettner schematic

[Zoldar71]

Hi,

I want to figure out a Hughes and Kettner guitar amp (Blue 15R) and found a schema online. But the capacitor identification puzzles me.

This is part of the schematic. Some capacitors have their true values, but others have a M-code. Is there a way to translate these codes into farad?

Cheers,
Martin

My guess is M104 is 0.1uf; M332 is 0.0033uF, M153 is 0.015uF and so on .

Thanx Barry, you are spot on.

I searched again today and found something I didn't find yesterday (hate when this happens ;-) )
