I played an amp at the local music store the other day and I'm pretty
sure that it combined a solid state amp with a tube preamp. I decided
that it might be cool to try to build a preamp and use it with my
existing solid state amp, just to experiment and see what I can do.
I've done some electronics before, but nothing with tubes and nothing
on this scale. I've messed around with distortion pedals and I've
built tillman's hunk of a preamp and I've built several op amp
preamps. One of the questions I have, other than general advisement
lol, is how many watts should I use for the tube preamp? I've looked
up some schematics and I've found several, but I'm not sure what
wattage would be appropriate. I've got a Roland Cube 60 that I plan
on using, so would a 50 watt preamp suffice or does it need to be
lower than that? Also, I've never dealt with transformers. Would I
be able to tap into the one that is already in my amp, or do I need to
get another one specifically for the preamp?
This is the one I was looking at. It looks like there are two
transformers in there too. I've been looking around for a good tube
preamp tutorial, but, as of yet, have been largely unsuccessful. Most
of them assume I already know how to build a tube preamp, which seems
to contradict the need for a tutorial. Anyway, Thanks for the future
