Hi! I have a malfunctioning tube guitar amplifier, and I think I have found a broken diode. I have little experience with practical electronics, so I was hoping to get som answers here.
First question: would you agree that this is a damaged diode?:
I did try the diode-measuring setting on my multimeter without disconnecting the diode from the board, and got a fluctuating result 10-100 both ways.
Secondly, I have tried to read off the text on the diode (there are three lines of text on it), but may be missing a letter/number in the second line:
1N
5380B
0622
(The last visible letter in the second row could also be an E)
Does anyone know for sure if I am missing a letter/number in the second row of the description? Will I need to get an identical diode, or would other types also work as a drop-in replacement? (I haven't found this exact one when browsing the net)
I would really appreciate any useful information.
Best regards,
