I just bought the Antique Sound Lab MG-Head OTL Mark 111 headphone amp.While I am overall very pleased with the sound,I have a question about the tubes.The 2 end tubes get very warm and bright,but the middle tube is just barely lit up and is just slighly warm to the touch.Is this normal or is their something wrong with the tube?And how expensive are tubes to replace?
