<< Someone on the list asked a good question about if the crossover caps in a
 Leslie need to be replaced. I would like to see other experts other than Al
 Goff and Bob S.who consistantly answer the questions. It seems latley people
 want to use this list to solicit buisness to buy organs and other
instruments
 but will not take any time out to help people. I guess its ok to loot
 something but not put a dimes worth of effort to maintain something . If
 their is nothing in it for me then the hell with it. Is that the attitude? 
 Well here is my attitude, if you want to be known for what you buy and sell
 on this list 
 then spend some time contributing to it and helping the people on it, or
dont
 waiste our time.  >>

Tony,
I've posted several messages on here regarding degraded Leslie output; with
little or no response.  I'm noticing more and more Leslies with grungy output
and, after much bench time and experimenting, have also realized that a lot
of the problems lie in the crossover.  Houses like MCM Electronics and Parts
Express have some good crossover-applicable coil and capacitor
lines--probably for the ever-expanding car stereo market.  We've built up a
few crossovers with these components and have had pretty good results.  With
new tubes and balanced caps and resistors under the amp, there's little else
that can go wrong, other than the output xfmr and the output system.  I hang
on to the old "square-back" 15s and put high-rated emenence parts into
them--16 ohm at 150 watt.  We're still looking for a decent treble driver
because, as you know, the Jensen parts are next to impossible to locate
anymore.  Emenence makes a driver that seems to do a pretty good job without
exaggerating things like the inherent crosstalk and key click and, believe it
or not, so does MG (available thru MCM Electronics).  As we cpntinue our
late-night experiments I'll keep everyone posted.
