Another flavour of Class A

Pass Labs F5 Power Amp.

A very nice amp. Nelson did a good job but it is not a SECA design.

I must admit, I don't think I've ever heard a Pass amp.

Why would you design a push-pull Class A?

AntiCrap

Much more efficient thus cooler and it will double power into 4 ohms, But for me the the distortion crossover type is lower but I can hear it.

A SECA design is a much nicer sound and Nelson did a design in the 1990,s but it was very low power,

Thanks for that, Col. I didn't realise they ran cooler.

You're preaching to the perverted about SECAs, of course :-)

Thanks Paul. I remember reading some of this stuff ages ago - must have been before that site, looking at the date, when I wanted to have horns, but didn't want a valve amp.

I'll give it another read.

Looking at this?
