Great condition GA-5. Still had the old filter & bumblebee coupling caps installed. Tubes were vintage, but checked as new! So, pretty much just a cap job was required. The main filter cap was an old paper/wax type. Someone in the past had subbed in individual caps but left the old cigar there. I elected to remove it and the add on's, then install a D-lab CUB1 power supply board in its place. The amp took off running, no noise. I sell amp boards on my website. d-labelectronics.com or you can check me out on [ Ссылка ].
