Hey Roy,
What is it you want to know about the Woods? The mono/stereo switch only affects the preamp out jacks (mono if you want to sum the two preamp outputs before an FX loop, or stereo if you want to keep them separate). The only other secret is the switch to change the amp to 220v which is hidden between the heat sink fins...
I might have a manual if one even came with the amp - but I'm away from home for a few weeks...
