Hi, in this circuit **broken link removed** I would like to replace the two base resistors of the first bfr96s buffer transistor (1k-270R) with higher values, so the oscillator sees a higher impedance and at the same time the buffer bias (voltage) do not change.
Can you suggest which base resistors should I use?
Is it enough to just scale them up?
For example multiply 1k by 10 = 10k and 270R by 10 = 2.7k
Since it is a voltage divider base bias it should achieve the same base voltage, but what about the impedance that the oscillator sees?
