Yo all!

My dear and beloved Leslie 760 has begun fizzling and humming in the midrange and above. I have pinpointed the problem to a dying treble driver, a Jensen V21 - original. According to various internet sources the stock driver is not very capable of high volumes, so I have decided to switch to another brand. What do you guys use in your leslies? RCF? Atlas? JBL? Which model?

Thanks a hundred!
