Default Speakers protection

Hi Hugh,

Do we need to have any speaker protection circuit with this amplifier?

Thanks,
Igor

Default STOP!! NO MORE ORDERS PLEASE!!

Igor,

The only speaker protection I would use would be DC sense, so that any DC voltage more than +/-2V or so automatically disconnects the speaker.

This is a separate circuit, however, and it mandates use of a relay, which many say degrades the sound quality.

That, I've found, does depend on the relay. The Amplimo product is designed for it and sounds good, I'm told.

Omron make one specifically for this task, but it's hard to find.

I do not use speaker protection on small amps and have never had problems, but, of course, YMMV.

Cheers,

Hugh

Hi Hugh
I was thinking that 20pcs is minimum to start GB#3! .... I just see that GB#3 is filled?
Hope that 2 boards more is not a problem.

best regards
tome

It will be a while before I can make up my boards so I don't mind letting Tome have mine.

Hi team - I was lucky enough to stumble across this thread in time to snaffle a couple of boards - have boards/parts/case just need the time and motivation. It strikes me that with so many boards out already that there should be more comments on the sound/performance of this amp. The ones I've seen look promising so I can't wait. I was lucky enough to trial a Naksa 100 amp last week, that was fun. Roll on Fetzilla !

I finally was able to finish and power up one of the FetZilla and finished the second one but not powered yet...

With only one of them working I can't tell lots on the sound but I love what I'm hearing so far.

Will do a full write up once I have 50+ hours of burn in time.

Hugh, did you go through your semis?

Ciao!
Do
