Tubes for UNICO Amplifier


I'd like to upgrade the tubes in my UNICO integrated amplifier. The UNICO has a 12AU7 triode-based twin-tube input.

Any recommendation on what tubes might take the UNICO to the next level, the cost, and where I might purchase them?

Many thanks!

hello dsc.
i agree with elevick, telefunk's from the late 50's to 60's
production are amazing tubes for the unico.
i realy enjoyed some phillips miniwatts (ecc82) production
from holland like amperex and siemens,very reliable tubes
with a real good sense of musicality,you can get a new pair
for around 50$ u.s.
telefunk's are the sweetest but some of the priciest too!
a mtched pair will go for 120 somtimes more!
tube rolling is great but everyone has his sonic preferency's. i simply reccomend that you should
buy a few pairs of different tubes and give them a shot!
the one's you do not enjoy you can probably sell back here
on audiogon,there is a good demand for 12 au7's.
my reply is a bit late but tought i would put in my 2cents worth!
