Yes, but you have not tested yet the amplifier in order to confirm the tests of simulator?
All this from interest in the construction of this amplifier. I have enough transistors 2SC5359 , 2SA1987 . Not be critical of the construction

Hi Nikosokey,

This amplifier is based on a formula that says that you will like it. However the formula needs more validation by having a large number of respondents giving feedback. We are exploring beyond stability and T.H.D. This amplifier should also be the most stable amplifier not only in this forum but in the world.

If you are looking for adventure and are willing to share your experiences please join us for an unforgettable experience

kind regards,

Harrison.

as you can see my input or signal wires is not shielded and no need coz the amp.is quiet and also used copper tube as spacer for the pcb and connection of my star gnd. to chassis.

in listenning test, surely it has beaten my carver receiver .I have used a behringer mixer with low ,mid and high contol and to control the volume of the signal because I did not put a volume contol on the amp.I compare the symef to my carver coz it has also high ,mid and low contol.

symef turned my tower speaker(yamaha) sounds like a big speaker.voice of the artist sounds big and the bass is very good even at low volume.I really like the mids and lows of this amp. thats why its sounds very natural to me.

thank you so much for this amplifier.I am very satisfied with this amp.it is really worth of my money,time and energy.Now my worries are over the amp. is working and sound is excellent.

thanks, harrison .I do love your symef amp. now.It is a treasure!

regards,
joel
I have quoted Drow, who is a pioneer capable of grabbing bull by horns . I have done this for those of you looking for a different kind of motivation other than adventure.

What will be your experience ?

kind regards,

Harrison.
