tube change

[darin505]

When I change my tubes in my ad30 head, do I just simply pull them out or is there something I have to unscrew?

I have an ad30 combo. ya just givem a firm yank and they should pop out. I'd use a rag to avoid gettin yer greasy paws all over the tubes. Also, if there is a copper wire that clips onto the 'nipple' on the top of the tube, you have to unsecure the copper wire from the the nipple in order to remove the tube. Its kind of a bitch getting them back in, at least on my model, so have fun!
