Why include a bass boost below around 130Hz - is that where your speakers give up?
English ability is limited to see don't understand what you mean
:hypno2:
voluem? cool
Thank you for correcting my English ability is very low
good job...can you tell us more why there are many irons?
and can you describe each one, looks interesting btw..
Use Chinese to express is no problem
English can't sorry

Re: post picture #2
Many transformers. (7)
Why?

4 inductance

thanks, this is all i need to know....
Resistors 1K*4
Don't forget cathode impedance when calculating resistance center.
Only important if you want symmetrical push and pull slew rates.
The lowest impedance is at the cathode (above the 1K*4 resistors),
but slew is not symmetrical here, so we look for the true center.

Translated to simplified Chinese, then back to English with Google.
Still makes good sense. So I think this message can be understood.

Google translate produces 为什么包括下面的低音增强130HZ左右 - 是,如果你的音箱放弃?
for AJT's question. I can't tell if this translation is sensible. as I'm a single language white trash American Reversing the translation produces "Why include bass boost 130HZ below about - is that if your speakers to give up?" which is somewhat garbled. "Bass" here means "low audio frequencies, not the fish.
Looks like the middle stage of your amp is a combination of a "long tailed pair" differential stage and a SRPP style circuit.
