RC Power-Supply Filter
Resistors R12a and R12b are in parallel. The All in O ne kit supplies five 3W resistors
for R12 use: 1.6k, 2k, 3k, 3.9k, and 10k. Each resistor can be used in isolation or in
parallel with one other resistor. Fifteen possible combinations are possible; the
resulting parallel resistance is shown in the chart at the top of page 13.The charts that
follow show the voltage drop across the R12 versus the current flow. Remember each
channel gets it own pair of R12 resistors. For example, an All in O ne line-stage
amplifier might run each tube with 5mA of idle current, for a total of 10mA per
channel. So by looking up the 10mA column, we can see the resulting voltage drops.
Thus, one 3k resistor will drop 30V, so a 280Vdc raw DC power supply will delivers
250Vdc to the tubes. An * denotes excessive current or voltage, so that combination
cannot be used without risking damaging the at least one of the resistors.
