Doxa 70B , 70SE, signature!

mono2n · 22nd May 2011, 02:49 PM

Does anybody have scematics ? . Fixed a few of these, not too complicated. But I like to have schematics, so i could maybe clone it.
What type of transformer does it use (voltage, amps ) I know 70B has two , are these the same as the one in 70 SE?
And why does the 70B get hot (normal) and the 70SE not ?
I know the 70B use BC245C and 246 as outputstagetr. I cannot remember what type 70SE use. Anybody knows ? I guess this has something to do with the temp. issue.
The 70SE sounds much better than the 70B yet the B is much more powerfull (suply) How can this be ?
And Whats up with this signature ? Is it based on B og SE ?
