hi all,
i posted this over at the dynaco doctor forums as well, but. . . i just did my first "mod" which was the basic soldering of a 1n4004 diode to the selenium recitifer. when i hooked everything back up, i got a LOUD buzz in both channels when the amp was turned on, regardless of volume setting or what preamp inputs were selected. after panicking for awhile (i'm new to soldering) i opened it up again and resoldered the diode. to my suprise, everything sounds fine now.
so what happened there? was a bad solder connection causing stray voltage to be all over the place? should i be worried about other damage?
thanks!
