Vintage Simmons Drums (UK) Users Group

Hi there!

There are chips (original replacement OEM) on ebay.  They are filter
chips, I believe...the link is:

As far as the potentiometers (the pots/knobs), you can just look at
these, then go to your local electronic supply store & order
these...or if 1 is broke off, just take it there & they can match it.

Just trying to help...hope it helps!
