Yeah. Check your plate and screen voltages on your output tubes 1st tho. You may need Filter can caps. Also check the voltages coming off the big can (bias cap) underneath. DC VOLTS and the highest setting you have (600V?). If the voltages are 10%-15% high you may need new output tubes. We'll deal with that later. But for now get the metalbone kit. Plates are pin 3 (420VDC), and Screens are Pin 4-8 (375VDC) (There should be a wire lead (Bare) running across all 4 tubes for the screens. Just check at the 1st tube where the supply wire (usually orange) hooks to the 1st tube.) Post the voltages . The Metalbone kit is basic and addresses the basic stuff (coupling caps and such.) but the documentation is great! You get a manual that is specific for the range your serial # falls into. And i think he throws in a single sheet schematic. (Check the site). Main Filter caps you'd have to get elsewhere. www.hayseedhamfest.com has can cap kits that include the cardboard covered one, and the bias can underneath. I would suggest getting the the single big "Dual can" vs. the individual caps as you are just starting out and it's a simpler installation.
