bora's legend 4 consideartions - Click HERE for Original Thread
sakis
i am sakis petropoulos and yes amplifier legend 4 and 8 was given to me from dr Bora for free and also given as request to operate in voltage from 56 to 66 vdc per rail

well this amplifier is working perfectly in voltage 40+40 volts but no matter how much i tried so far to operate at 66+66 volts i end up with burned mosfets burned speakers and a lot of smoke

i have grate respect for dr BORA and also his designes i am extremelly thankfull cause he gave this for free to me and also willing to help and suport me with alot of suport
enenthough we all very well know that he is in a difficult moment of his life ......

to my understanding maybe dr Bra missed that my rails are 66+66 volts and may be many things need to be chanched to operate at this voltage ....thats ok he done a lot so far and i know very well that may be he canot do more at the time so i asked help from all you forum guys and seems that after a long time i am getting somewhere .....


also didnt know that dr Bora was sick so i made posts saying that probably dr Bora didnt help me out i could neverthink that he might be in a hospital

I APOLOGIZE FOR THAT ......

but otherwise i never altered or chanched any of my request or the amplifier spece

Hi,

Check this thread with my comments on that "+/-66V" design:

PS.: Only for accuracy. The genuine design that you call "Legend" isn't Bora's work, but Nelson Pass's. Called "Citation 12", published in the Audio Amateur magazine in the early 80's. Bora only added some tiny modification.
