Time to retube the C-J pre amp and amp. Looking at Genalex Gold Lion tubes at $46.00 each vs Electro Harmonix at $26.00 each. Need a total of 7 tubes. (4 for pre amp and 3 for amp). Any reason to spend the extra money on the Gold Lions? And, any need to spend the extra $5.00 per tube for matching? Thanks for the feedback!
