Mains Transformerless amplifier

Never said the capacitance value did.



The TS said "not concerned about hi-fi sound ", so I winged a number for 100 Hz.



Don't like running electrolytic caps at 75% of rated voltage. That is what could be across the output cap if an output transistor failed short (depending, of course, on the actual circuit topology).



Didn't say they weren't. I pointed out that they are way more expensive than "normal" parts, in a thread with "as cheap as possible" in the 2nd sentence.
