Did you do a little service work, like pulling the valves and reseating them, first? If that doesn't work or help, question two, Were you happy with the old sound? Have you heard someone else, use a different valve, and you liked the difference, there is a reason to change. Does the manufacture offer any suggestions? Regards |
