I was checking the cathode follower schematics, and have some questions:

a) I saw one circuit using E182cc, then when I checked the spec of the tube I noticed the Ia is typically 20mA, and it was mentioned that 4x E182cc can produce 10w output..... do they get this 10W by using a output trans or high impedance speaker?

b) If I use capacitor coupled output (paralleled-tube cathode follower), what kind of output current can I get from one E182CC? If running @ the typical Ia=20mA.

c) If I were to use low voltage tubes, say 24V car tubes, is it better to use low impedance phones? (since 24v is very low comparing to other tube circuits) Assuming the output current will be adaquate by paralleling more than one tube.

d) in a paralleled cathode follower configuration, if I use more than one tube (paralleling tubes), do all the tubes have to match? what happen if they are not matching?

Thanks for any help
