Tube mods on solid state amps ?

[SpareRibs]

Hello,
      Thanks teemuk, that should keep me occupied for a while. I am coming to an understanding about op-amps using the (all about circuits) information. It's not that difficult to understand the concept it just
takes a while to sink in as there are so many things going on all at once.
       I will look into the other information soon. I bookmarked it. I still have some more information to digest
from the op-amp site
       Thanks again.

you could bypass R2 with a capacitor and have a somewhat similar effect as bypassing a cathode resistor, since it affect the gain ratio dependendt on input frecuency...
i supose thats the idea of bypassing a cathode resistor.

you can use the following formula to find the crossover frecuency (F₀)
F₀=1/(2pi*R*C)
or
C=1/(2pi*R*F₀)
