Colitas, The HFN bias test tone varies from inaudible (good) to a steady "buzz" (needs adjustment) to a rough or warbly buzz (dangerously near mistracking). Unfortunately, bias force increases as the arm tracks across the record. So there's no "perfect" antibias setting, just a good compromise. As a rule, the anti-bias scales on Rega arms are off. Most people set it somewhat lower than their measured VTF.
Is there an azimuth adjustment on an RB300? I didn't know that. On my system switching to mono reduces the signal to a whisper, but not total silence.
Great post Lugnut. Agree about bias tracks on the HFN record. Why are they all near the inside? Tracks 1 & 2 are pretty useless anyway, they should have included just tracks 3 & 4 and duplicated them near the outer edge.
I've never looked to see if different antibias settings cause a visible change in cantilever angle. Might depend on the compliance of the cartridge. I suspect low compliance carts could be significantly mis-biased without displaying much visible deflection of the cantilever. You'd only know by stylus and/or groove wear.
Maybe Twl will straighten us out.
