However, I'm now thinking of either making Merlin Blencowe's Vibrotron or a full tube-based UniVibe based on the Vintage Vibe (schematic here). I'm leaning more towards the Vibrotron because that's full tube... what do you guys think? Does the Vibrotron look like a good candidate to produce some nice vibrato tones? According to Merlin in his AX84 thread, it should have the same workings as Magnatone's vibrato circuit, but without the hard-to-source varistors.

Yeah, I tried to make this point.

Much as I love this stuff, I have a hard time differentiating between tremolo and vibrato. The clips on DIY stompboxes sounds more like a Fender "harmonic vibrato" to me - where highs and lows are split and the modulation on them is 180 degrees out-of-phase - except a real harmonic vibrato is more lush (based on the clips).

The Merlin clips are no longer available, so I can't judge there, but he is of course one of those guys I am more likely to assume he did what he said he did.

If you can find an old Hammond AO-41 amplifier, you can use the saturable reactor - check this out - https://sluckeyamps.com/warbler/warbler.htm
I can hear the pitch-shifting on this one.

Haha sorry, I'm not one to quickly give up but more research and your guys' comments had me stumped eventually. Worth a shot I suppose.

I understand what you mean. I guess I'll go for Merlins Vibrotron, I'm willing to take a shot at it even though the clips are no longer available - the comments in the thread seem pretty enthusiastic about the achieved sound though.

Yes! I've stumbled across that option as well this morning and have already done some searching for an AO-41 or an AO-47, but have not yet come across any. I've also tried searching for substitutes for the saturable reactor but I've read in a few places that these components were specifically designed for their purpose so the probability of finding a substitute is next to zero I suppose...

If I go for Merlins Vibrotron as a standalone unit, could I safely feed it with the 30VA Toroidal transformer? I know it puts out 200 volts which is 50 more than Merlin used for his unit, but I'm unsure whether it will affect the circuit badly - I'm a bit new to the tube technology and have limited knowledge but I am eager to learn :)
