Now it's my turn to sound like a newbie, but hey, I'm a repairer, not a designer... :grin:
How do designers choose the value of interstage audio coupling caps? I have some gear that uses 4.7 microFarad caps, such as some ADR stuff, yet I notice with Joe Malone's circuits that he supplies for his new preamp boards some of them are in the thousands of microFarads. Is it a function of impedences of the stages? How is HF and LF rolloff effected by such divergent values?
