Hey,
awhile ago I had purchased a Sunn Model T from eBay. It's been a year and I can hear the sound just isn't the same anymore and I've shown my friend and he said it's the tubes.
Now he says it's a difficult process to do, that involves tuning them and whatnot and such. I recently asked a guy at a regular shop and he said all you do is just pop the tubes off and put the new ones on. I figured you guys here would know the correct way of doing this or could help me out.
