Vintage Simmons Drums (UK) Users Group

My SDSV is at the shop trying to be repaired. He can't do it. His problem  is 
with the buttons. Can any one help me find a reputable Simmons repair person  
that can completely go thru my unit and clean check and service the unit so 
it  is fresh and new again.  I need your
 help

Hi,
my Name is Michael and I live in Germany. I may not be a reputable Service Person, but I know the SDSV by Heart (I built one on my own 20 Years ago because I couln't afford an Original, but today I have it, with all available Modules), so I can give your Repairshop all necessary Information. I have drawn a basic Signal Flow Schematics 20 Years ago, you can download this at www.simmonsmuseum.com. You have a Problem with these Preset-Switches, am I right? So I have to know: What is the Problem with the Buttons? Are the Buttons themselves worn out (You have to press hard or many Times to change the Presets) and you need only Spare-Parts (Only one LED should be lit on the Module Front if you push a Button)? Or is the LOGIC behind these Buttons the Problem (maybe one, two  or no LED is lit, others gleaming, or you push Button for Preset 1 and the LEDs of Preset f.e. 4 and 2 are lit together)? Then you have to change IC2 in most Cases (4556) or IC 1 (4013). Both very cheap.
