Hello there,
I've been looking at the schematic for the studio .22 and i'm a bit puzzled.
Usually (as far as i can tell) amps have a 1M pull down resistor in front of the
first valve stage as this sets the amp's input impedance. But in the studio.22
i've noticed in addition to the 1M pull down resistor (R103) there is a parallell
cap/resistor array before the pull down resistor: 47pf (C6) / 3.3M (R104).
Can anybody tell me what these do/are for?
Also i'm struggling to understand how the lead function works. Can anybody
explain what happens when the lead function is engaged as i've never come
across a cascading system like this.
YES i am a bit of an electronics noob as you may have gathered, but I find
it very interesting and would like to learn more about it.
Any help you can give would be fantastic.
Cheers.
