Dieter,

Fully understand about reluctance to work with tubes.

I believe that Eric of Metasonix is looking into Euro format tube
modules.

We will not offer tube modules because of the perilous voltages that are
necessary to run the tubes. It would be necessary to built each module
in a
separate box because of the electrical safety. Another problem is the
power
consumption of the tube heating. This would require another bus
structure
with an additional "high power/low quality" voltage as it does not make
sense to take the current for the tube heating from the high qualitiy
supply
voltage.

I don't see a chance for Doepfer tube modules in the foreseeable future
:-(

Best wishes
Dieter Doepfer
