Thanks for the suggestions. I switched out the C10 cap a long time
but I'm a little hesitant to mess with C9. You don't think switching
the 12AX7 with a 12AT7 will help much?
Also, anybody taken out the circuit card? If so, how did that effect
your tank's sound? Anyone know of a good site that explains how to
remove it?
Thanks!
