This is per the original schematic, not a reissue. I made the transistor pinouts to match your basic transistors and i think that 2N5088s should work just fine in there. Original units have 2SC945s in them, so mind the pinouts and twist the legs if you want to use those. Medferret’s demo clip of his … Read more
Simple, but still seems like one of those super problematic circuits 🙂 This one goes published as unverified for Madferret, who was after a unverified tremolo layout. So. Here you go. Let us know how it works out 🙂
This one is definitely verified, but: The LFO section is *very* sensitive to both voltage and current, so if your board doesn’t fire up right away (which happened with my second build too), you should consider doing a little daughterboard with 9V regulator, 8V2 zener and a 10-50 trimmer to get the LFO going. That … Read more
.. awaits comments asking what the bloody hell is that! :o) I think a few people will like this, a really great sounding tremolo. The 2N2646’s are obsolete but still available from a number of places, RS, Farnell, Mouser and a few sellers on eBay. They’re not as cheap as the more common silicon transistors … Read more
Actually a very nice sounding tremolo rather than the effect the name suggests. A clone of this is currently being sold by a company called Mahoney and they wrote: In the late 60’s, Jordan offered an incredible sounding tremolo unit that was housed in the plug-in style box like the Bosstone. There were less … Read more
Request. I’ve already done the Hearthrob but someone asked for this, and you can never have too many tremolo options I suppose. Some of those transistors look like they may be difficult to get hold of, so I’d probably just use 2N5088’s which work fine in the Hearthrob. If you do use other transistors make … Read more
Requested by a few people. This uses a vactrol but it might work with a roll your own LDR if you want to give it a try. The spec of the VTL5C1 is 600 ohm on resistance and 50M ohm off resistance. If you would prefer a tempo rate LED instead of a standard always … Read more
Now fixed and verified MarkM’s tremolo based on the Schaller: Geiri’s demo of his build:
You may struggle to get hold of the 2SC828 transistors, so just try any high gain NPN silicon. Just make sure the pinouts match, or use some small heatshrink tubing or offcuts of wire insulation and twist the legs if you need to. Geiri’s demo:
Here is an adaptation of the EA tremolo with the schematic done by runoffgroove. http://runoffgroove.com/eatremolo.html Their notes on it: Modifications to JD Sleep’s version are: * Input buffer and main gain stage have been combined into a single MOSFET stage designed by Gez Paton. * The “pulsing LED” by Darren Inwood and Rob Strand. … Read more
