I'm on the lookout for a good generic spring reverb driver circuit, now that I have an 18" Accutronics box. I found one in an old book of electronic circuits. It basically has a two watt amp IC (LM 377) pumping audio into the reverb, then two stages of low noise preamping (LM387) at the other end. I think this is a good way to go, but would be interested in what any of you gurus and veterans might have to offer. You'd like to know what folks think of using this circuit with this reverb tank but you won't tell us the model number of the tank or the source of the circuit? Hmmmm. Accutronics makes numerous models of tanks in various sizes, types, decay parameters, input impedances and output impedances. It's clearly a good idea to get a circuit matched to the tank. Accutronics will gladly send you a book of circuits, hints, and recommendations for free, just ask them.

From: gstopp@fibermux.com Date: Tue, 26 Nov 96 16:46:40 PST I have heard (can't remember where) that the Accutronics spring units come in different models, with different transducer impedances. Is this true, anybody? Also I seem to remember that some tanks had a sticker on them with a humorous comment about the place of manufacture. No, that's another company. The label said something like "Made with pride by beautiful girls in Green Bay Wisconsin". I can't remember the company's name right now -- anybody know? Are they still in business? -- Don From eli@gs160.sp.cs.cmu.edu Fri Dec 13 08:54:15 1996 13 Dec 96 3:36 EST id IAA147263; Fri, 13 Dec 1996 08:31:21 GMT id IAA153131; Fri, 13 Dec 1996 08:31:02 GMT Date: Fri, 13 Dec 1996 00:26:17 -0800 (PST) CC: synth-diy@horus.sara.nl In-reply-to: <32AF1774.D2F@hookon.be> (message from Bert Schiettecatte on Wed, 11 Dec 1996 21:20:04 +0100) Subject: Re: Spring Reverb From: Don Tillman Organization: Don's house, Palo Alto, California Date: Wed, 11 Dec 1996 21:20:04 +0100 From: Bert Schiettecatte another question ... does anyone know where I can find some (high) quality springs for use in an analogue spring reverb unit ? Anyone got some spring reverb schematics ? The very best source of reverb circuits is Accutronics, the folks who make most of the reverb tanks. They have an application note full of circuits, theory and helpful suggestions available free for the asking. Accutronics is now owned by a company called Sound Enhancements.
