[78-L] Fw: styluses

[Francesco Martinelli]

Thank you very much for all the answers. I did not explain myself clearly, 
the sound is there but exactly like Iñigo described "a big noise and a very 
faint signal". I think I need a wider stylus, wider than the 3 mil one I am 
using now. Unfortunately borrowing is not an option so I will have to ask 
Esoteric Sound again...

It could well be the hill and dale system, or maybe it's as simple as a very 
wide lateral groove. In Spain some old Odeons have it so wide that a 
standard 2.7mil stylus gets lost into the groove bottom, sliding from side 
to side, and producing a big noise and a very faint signal.

To test if it's a vertical groove: you need a stereo cartridge. Are you 
using one, I suppose  ??? Then take the stereo cartridge out from the arm, 
and revert the polarity of ONE of the channels; replace cartridge in the 
arm, and select MONO in the amp, mixing the two channels. Thus, the 
cartridge will now emit vertical component only.
