Default Yes Buzz... this makes a lot of sense.

This amplifier can work from 15 plus and minus to 64V plus and minus....so...you may have lower power if you need...also you do not need to use all these output transistors while using lower supply voltage, that will result in lower power output because the lower supply voltage.

Visit MKIII thread...there you have this posted in questions and answers i have made to myself in order to help buiders about this kind of doubts they may have:

Dx Blame MKIII Supercharged will soon be released

regards,

Carlos

If this is true, I still want my boards. I assume there is no sound degredation with less ouput transistors?

Default I have tested using 21 plus 21 volts supplies and sound was perfect

We have to tweak bias circuit resistors as explained in previous recent videos.

I have also tested using 35 volts supplies (Home Edition)

Also tested using standard supply voltage.

Just for fun i have checked with two 9 volts batteries and worked fine too.

I do think from 35 to 64 volts result was better....well, lower power in December....if you want optimized units for low power, then is better to cancel your order and wait December.

I will not help modifications for this model to avoid to become crazy...as i may have too much work thinking about several different amplifiers at same time.

Sorry, i am already developing, and testing, 5 different amplifiers...this is already too much....amplifier is a system....to each power and supply voltage we have to adjust several things to optimize performance...each one must be understood as a different amplifier.

Reduction in power and supply voltage will allow amplifiers to operate...but not optimized having the best possible performance....want the best possible performance to lower power units?...then wait December.

This amplifier is a monster!.... a killer!..... be carefull if you have sensitive low power speakers...they will melt...this is guaranteed

regards,

Carlos

I will wait then. Pleases remove me from the list. As I said before, I will honor my agreement if Byron is left with boards.
