Greetings
Allow me to display [some of] my ignorance here. Is the tuned input circuit in
these amplifiers for the benefit of the driving transceiver to allow it to see
the proper impedance, or is it to act as an attenuator for out of band sporadic
or impure emissions for the benefit of the amp?
My question arises because I have an sb 221 which I have had sitting around for
a while after buying it from the son of an SK. The builder did not build it to
spec, as he left out the CB filter, the ALC circuitry, and the relay. Looking
yesterday at the rf input, he took it past all the tuned input circuitry and
straight to the final tube, through one cap. My plan is to correct all this,
but his method got me to wondering about the tuned input
Would the amp perform OK in this configuration or would you be likely to create
some damage? I plan to change it anyway, but am curious about the answer.
Thanks and 73
