Don't include me in the we're bit.
Great, stick with them.Hemmo1969 wrote: ↑Tue Nov 05, 2019 4:54 pm Afternoon all,
I'm pretty lost when it comes to all the technical jingo that many of you guys can talk, especially on the DIY threads. Although I do like to read em I wouldn't mind understanding a bit more. So this had me thinking when I read some of the latest bumf on a new amplifier to be released what the hell it all means and does my amp have such components? I'm currently sporting a pair of A80s MkII mono blocks in my system of which I adore.
Marketing hype mainly though polypropylene capacitors are generally considered superior to other film type capacitors for audio.So if you read the excerpt below, what then is or the benefit of;
- Polypropylene capacitors
- K-Power reserve capacitors
- An output stage using 4 x 160w Sanken output transistors. Are Sanken even a good brand.
Many a good well regarded amp has a single toroidal transformer powering two channels. Having sufficient current from the transformer is what matters, some designers like to get that using two others are comfortable with one. Obviously monoblocks will have one each.Yours with appreciation...... Mr confused.
- And secondly looking inside said Amplifier there just one big toroidial transformer? Is this really the best way 1 x big I thought NVA Amps had multiples of on either input or output?

All you will get from your question is other peoples opinions, if you want facts, then you will need to spend five years learning electronics to understand the answers, by which time you will not need the question answering anyway.So 690 views and 40 odd posts and I'm still no more educated than when I started (Bar the one sensible post)
Absolutely, my comments are mere supposition, I didn't design the amplifier in question and I have no idea why the designer did things in the way they have been done. Nor do I know why the marketing department put so many meaningless technical words in the advert.Lurcher300b wrote: ↑Wed Nov 06, 2019 9:06 pmAll you will get from your question is other peoples opinions, if you want facts, then you will need to spend five years learning electronics to understand the answers, by which time you will not need the question answering anyway.So 690 views and 40 odd posts and I'm still no more educated than when I started (Bar the one sensible post)
They will have looked at the expected power output required into various loads, then looked at the SOA curves for the output devices, then decide what safety margin they need and base the number of devices on those things.To be fair, I would like to know why they chose four output transistors per channel?
