hi,
just discovered that last stage of pre amp is EQ transistor cascade stage , and signal path through it, EQ used or not !
at the output of this stage these is a coupling cap , not a life time sprague film one, but an electrolytic 1uf , at this small value this part last not so great along the time as it could be dry (it is not automatic) , so when people recap filter big blue ones, they should get a look at this C411, if its a electrolytic !
i personnally would drop in a 715p 400v sprague 1uf, as all the signal chain is prop film why changing?
it brough for me this amp some life back!
enjoy
