Hi
This is a FREE pcb from China, according to the webmaster, this is modified from MF E10....
and I took a while to put it together, using my own stock, except the a few resistor and transformer. So a free PCB with my inventory, very cheap......
This is the whole top view
One channel
Using MJW0281/0302 as power BJT
It seems that MF like to use Jamicon as filtering caps....immitation
MUR860 as bridge
I put it in a integrated case, so add a ladder step att
Changing LED bias R19 to 2SK246
mount the bias BJT on power BJT
The supply of voltage amp stage is MINI Regulator
The look of the int amp
A very beautiful sound....nice and easy....bass is a little bit less
Very musical one.
cheers

An externally hosted image should be here but it was not working when we last tested it.

Hi Coffin,
I like your new amp, nice work!
As I see, you were using so high quality components!
On the margin the schema reminds me MikeB's Symasym...

Hi
Just got those "high quality components" in my stock, so...why not using them?
Yes I think the topology is very identical.....except PNP not NPN
