Standalone tube vibrato/tremolo unit
« on: August 02, 2021, 12:38:19 pm »
Hi guys,
first of all thank you for all the information I found on this forum, this really help me in building tube stuff.

I found an old thread regarding this topic and so I decided to start building a Stand alone tube vibrato/tremolo unit based on Merlin's Vibroton schematic I attach

I'm using an old ATX PSU steel case for the chassis and using a DC Booster for the HT supply from a regulated 12VDC supply I use for the heaters.
I share the version of the resulting schematic with mods.

Any suggestion regarding this circuit? Did someone already build this tube unit?


Thanks a lot

Welcome. Thanks.

560pFd at the grid of the LFO phase splitter? It may work but seems awful small.
