Capacitor-less amps


I've read some amps have no capacitors. Is this a good design?

Just FYI, an amplifier without COUPLING capacitors (ie without capacitors in the signal path) is called direct-coupled. All the direct-coupled amps I know of (but I don't get around much) are solidstate. All tubed amps I'm aware of have at least one coupling cap per channel in the signal path.

"There is some confusion: "in the signal path" means in series."
I agree; that's the definition I always understood.

"Decoupling capacitors are in the signal path."
'Decoupling' usually means a relatively small cap from DC power to ground that isolates one part of the powersuppply 'line' from the next. Decouplers are NOT in series so are not in the signal path. Did you mean COUPLERS?

"Parallel caps are fine and necessary - cleans up the signal which everyone likes."
You'll have to be more specific for me to understand what you mean.
