If you make some pictures of the component and track side of the pcb it should be posssible to sort that out for you.

Maybe you could take a 2N4303 (and a 2N4250) ?

Update: Well, I found a local guy who was willing to fix my thumping Twister - Laurie at www.dingotone.com
He found that a trim pot was out of whack. (I guess the previous owner had fooled with it ) So, It's a great sounding phaser again! All is well!
Thanks for all the suggestions. :applause:

Seems there is no sound clip of this original unit on the web in order to have an idea of the sound of this effect... any link is welcome. Tx
