Sad news, my Herbert is blowing the main fuse and the T2 fuse inside the amp. I changed the fuses with the same exact fuses. Then I changed the pre amp tubes and the power tubes and biased each set to the diezel website 65ma per set. Now it has a loud humming noise when you turn the amp off standby. All the tubes are glowing normally and I check the bias again and everything is right at 65ma. I don't know what the problem is. Guessing I would think its a Transformer cause it has that 60 cycle humming. On Standby with the volume down its a high pitch whining noise.
So now here is the problem. I read the warranty info on the Diezel site and since I'm not the original owner the warranty is void.
The amp is a 2008 model like brand new not even a year and a half old depending on what month it was made in.
Please HELP!!!
