The biggest problem on building your own tube reverb unit is to have it hum
free.
The reverb pan picks up the magnetic field from transformers and wires much
to easy.
I have been experimenting with a diy reverb and this is the point where I'm
stuck.
When I place the pan 1 meter away from the unit it sounds great but this is
far from being practical.
In the mean time I'm experimenting with a solid state reverb. This must be
easier to have it hum free because you can use a wall wart power supply and
keep it far away from the unit.

Wannes,
Good advice, and that's the reason I asked in the
first place. A schematic isn't nearly enough for an
inexperienced builder (like me), and even most layouts
are too vague to insure a smooth build. I was hoping
to find a more detailed project that listed the right
transformers to use, test data, etc. Hoffman's site
() has what I was looking
for.
As for cost, you're certainly right. I always get a
kick out of new amp builders who list their reason for
building an amp as "to save money." I've accumulated a
lot of parts, so I don't have to buy everything for
just one project. Plus I enjoy it, and learn a lot.
Thanks for the input.
