As you may know from posts I made a few months back (before I moved
house) I have been doing some work on using 6AU6 tubes in triode mode
for preamps. The set up I have at the moment is pretty crude. I stripped
a chassis from an old battery valve radio, wired in the components I
needed then bolted it to a piece of wood along with the mains
transformer and PSU components. This is OK as far as it goes but apart
from looking tatty it is not very easy to make circuit changes but, as I
am making noise measurements, layout is crucial.

So.... I was wondering if anyone makes something I could use as the
basis of my experiments that would be easier to modify?

Any ideas?

Cheers
