BAT VK75SE buzz and humming ?? help..

would this thing be working if it had a blown fuse... where should I be looking.. I do recall having extra fuses in the box..

thanks

AA Capitole plain isn't compatible with some amplifiers when using balanced Interconnects because of a "pin 1 problem"which can cause a line level signal ground loop. See my thread regarding impedance mismatch for more information. Could be your problem

Hey Mejames, I have heard that, but there is no issue with that as far as I can see.. the buzzing still happens when the components are unplugged

thanks

If a output tube fuse is blown, it will work, and it will increase the hum considerably. Also a channel should have less power-like 1/2. If one in each channel is blown, it will still have balanced sound-but with lot's of noise and basically sound like sh&%. Look at the output tubes. Are the 4 led's on and green? If one is off, then you have one output tube fuse blown. If one is red, then a problem with the auto bias circuit (more likely a bad tube). I have had some issues with bad output tubes...replace one about every 6-12 months. No big deal though.

To replace a output tube fuse, UNPLUG the amp from ac, turn it over, and you'll see the fuse holders underneath.

Thanks ..

all LEDs are Green and functining.. but I will check the fuses anyway..

Wow.. tubes are work ..hehehe
