Leslie 145/147 Speed Change Noise

["Spence, Colin" <cspence@nelson.env.gov.bc.ca>]

With the passage of time and the addition of some new subscribers, I thought 
this might be thw time to ask an old question that has remained largely 
unresolved.  My Leslie 145 makes an irritating *snap* in the audio signal 
when I change speeds especially from low to high speed.  Additionally there 
is the electro-mechanical click of the relay.  In live settings with the 
guitar player's Fender Twin beside me I can't say it makes any difference. 
 But at home or for studio stuff, the situation is a little different.

I would appreciate any advice on how this problem might be rectified.  Short 
of converting to a 122 amp (and changing my Hammond 1147 XB2 preamp to and 
1122 - *gasp*), are there other solutions?  In an ideal world I'd like to 
replace the relay with something solid state and clean up both the audio and 
electro-mechanical noise.  Any further ideas other than what was talked 
about when this surfaced a few months ago?  Al, does your shop have some 
wizardry to get at this besides the complete rebuild to 122 specs?

Thanks!
