Hey guys iv'e got my tube amp and everything set up but i have this problem!

There is a weird sound blip that goes on my speakers it's like the sound stops for half a second then resumes and does this again 3 secs later on both my speakers so it's like pulsing between the two, is it the tubes becomes it doesn't do this when you first turn on the amp.

The two output tubes operate in a fairly efficient class AB mode. When you remove one tube you are now in a much less efficient class A mode, which means the power consumption could go way up, causing the power supply to cut out, or even causing serious damage.

Please look around at what $200-300 can buy you in a nice solid-state amplifier or receiver.
