Dumble input impedance

Post by tubey »

Maybe a typical newbie question; can anyone tell me what the input impedance of my 183 clone is ?

Is that simple to measure / figure out that by myself?

Thanks !

Should be 1Meg and 3.3Meg for the FET

BTW, determined by the resistor to ground on the input jack.
