Is this easy? Since this is frequet mantenance they didn't make it rocket science. Yes it's easy. I don't know your model though but still, the general idea must be the same. EL84's, if that's what you have, sit with thin pins and usually a spring or cap on the top to keep them in place. Removing it is like when the nurse taking a blood sample switch tubes. Be careful not to use too much force or you break the tip. Spray the pins of the new tubes with electric spray, jack em in and out a few times to lubricate and make perfect contact for the new tubes. Especially important for the smaller tubes with thin pins that can point in any direction. Be careful not to bend the pins when you try to mount them. That's the only cons of EL84, their weak spot. Use gloves or a cloth to not put grease from your fingers on the tubes. Change tubes is a thing you can do for sure. Just take it slow and easy if you're unsure. Never use force, that's when pins and such break. On and check on how to bias, or are all Mesas self biasing? -------------------- My bands homepage

Okay, that would be very easy. It's just a 1/4" jack into the output. Speaking of speakers, what do you guys think of my cabinet+combo-as-a-head idea? Another plus I can think of is it would give me a nice space to store things where the speaker used to be. I probably won't do this for some time yet, but I wonder what speaker would be best with the V30, if not another V30. And then there's the different back configurations, closed, open, 3/4... I think it's a very good idea, you'll have a more bigger sound to work with on stage or in studio. For home use, it doesn't have too much sense - one speaker will create enough bass. What speaker is a bit of a wide topic, there are so many out there, and it is highly subjective. Experimenting is the key (often it is not possible, but it's the ideal way of getting to know them). I think putting two different speakers is a good idea, because you can instantly compare them in the same box. I like closed back, they have more bass and the sound is focused towards front. You can try some cabs and see what you like. -------------------- - Ivan's Video Chat Lesson Notes HERE
