My tube fuse (1/2 amp fast blow) of right channel keeps on blowing. I checked the manual and it says i should check if the red led is not light then that tube is blown.
But the problem is non of the LED is on as there is no bias current because of blown fuse.
Then how do i go about finding which of the tube is shorted.
BTW its a Cary Tube Amp. Its has Quad El-34's for each channel. The left channel is good but there is the a problem with the right channel.
Here is the link to the amp specs http://www.caryaudio.com/products/audio/cad280sa.shtml
I'm very new to tubes so excuse me if i have said anything incorrectly.
What's the best way to find out which tube is shorted so that i don't keep on blowing fuse. So far I have blown 3 fuses.
