TubeFex qui est apparément le méme que le TranstubeFex

http://www.peavey.com/media/pdf/manuals/80302283.pdf

The main difference between the Tubefex and
Transtube Fex (other than real tubes) is that the XLR direct outputs on
the Transtube Fex have an exterior speaker simulation feature - a
switch actually.
