Andrew,
Glad to hear the ole' trial and error is working for you too! Larry found the Wally buried beneath some old record sleeves and used pads from his cleaning brushes, but now I guess you don't need it. :-)
I'll have to try a mono LP for azimuth adjustment again. Whenever I've felt like fiddling with it I've just used whatever was on the table at the time, which is likely to be stereo (around here anyway). If nothing else I can verify what I've done, and if it's easier I'm all for it!
Nsgarch,
I don't have a mono/stereo switch either, but if I did setting it to mono would make azimuth adjustment impossible. Summing the info from both channels would negate any L/R adjustments made to the stylus. Azimuth is about reducing crosstalk, whereas a mono switch forces 100% crosstalk.
