[Elecraft] Re: K1 Resistance Checks

[Wayne Burdick]

The nominal resistance from pins 2 and 3 of an LM386 to ground is 150 k, but
this apparently varies considerably from one lot to the next. The resistance
chart will be changed to "less than 250 k" to accomodate process variations. A
higher input resistance here will not affect performance.
