removing tubes effect on voltage

aron	removing tubes effect on voltage Hello, If I want to remove tubes from a circuit, what is the easiest way to keep the preamp voltages around the same as when the tube was "in circuit"? There are 2 cases: One is that I want to remove 2 or more tubes from an amp. (12AX7). The other is that I want to remove an EL84 (reverb driver tube) and 12AX7 from another circuit. Is there an easy way to "simulate" the tube being in there so the voltages stay roughly the same to the remaining tubes that are in the amp? Thanks, Aron

removing tubes effect on voltage

Hello,

If I want to remove tubes from a circuit, what is the easiest way to keep the preamp voltages around the same as when the tube was "in circuit"?

There are 2 cases:

One is that I want to remove 2 or more tubes from an amp. (12AX7).

The other is that I want to remove an EL84 (reverb driver tube) and 12AX7 from another circuit.

Is there an easy way to "simulate" the tube being in there so the voltages stay roughly the same to the remaining tubes that are in the amp?

Thanks,

Aron
