The amp: SDC 200

Wednesday, June 24th, 2015

First I have to apologize for not posting for such a long time. In fact there would have been enough to post and I will try to catch up with all those nice topics during the last year. This time I have some pictures from an SDC 200 restauration project. This amp had been designed especially for Simmons drum kits. It has separate channels for kick, snare, toms, hihat and cymbals. 200 Watts amplification, a 12″ mid/bass speaker (ILP 312S, 12″ 8 Ohm) plus an Audiotech HF 200A piezo tweeter. The power is ok for personal monitoring, but at least I have heard about many blown speakers and I was adviced to change it for something stronger once it got broken.
However, it’s a rare collectable and I am glad that I got one about 1 year ago. As all SDS 200s I’ve seen before, the foam panel as well as the light blue hexagon disppeared over the years. The artificial leather coat got gray and dusty. Fortunately all knobs are still in place and the amp works pretty good. So all restauration jobs are cosmetical. Simmons used many parts from supplier Adam Hall like the edges, the black coat, wheels and the panel foam. These parts are still available!


This is the amp as I actually got it. I did some testing, took a look inside:

For the cosmetical issues I removed the amp part from the chassis and removed the protection edges to clean and fresh up the artificial leather:

The most interesting part is making a new front panel. I cut a frame from thin wood strips and stapled them to a frame. Afterwards I stapled the panel foam as well as the hook-and-pile tape to the wood stripsx:

Finally I cut some piece of light blue rubber foam to a hexagon and stuck it to the panel:

And here we are! It’s no rocket science and I am glad to have saved one of those amps. I doubt that more than a “handfull” of SDC200s are still in use and working. I would estimate that Simmons built around 500. Anecdote: After carrying this monster back in the basement storey I got a bad back for 3 days 🙂
