You can also start with these tubes and then you can always change to much
more powerful tubes later. The current coil that I am messing with started
with a single 811(not A) tube, oh I think about 30+ years ago. Have tried
several tubes going bigger over the years on it, off and on, as I gathered
up more components slowly over time.
Or go ahead and get a big fella from the get go. You will have to decide.
I would guess 10"-12" with these also like John says. This would be
non-pulsing.
I also prefer more powerful tubes also now.
