Professionally serviced. S6420 Late 60s, Supro Thunderbolt with JBL D130F. Good testing used tubes: 2 6l6 wxt, 1 5u4, 2 12ax7. New filter caps, new 1/4" jacks, new grounded 3 prong power cord. Yes it's rough and not pretty, but let's call it genuinely relic'd. Structurally solid. Worn and torn original tolex. The internals and transformers is what really counts. Guts are good (pics upon request) We may still mod this to add the xtra gain stage from the first ax7 cause we can, but wanted to see if anyone was interested in the original circuit first. Sounds killer with a D130F! Hell with this speaker it can actually be used for a bass or guitar!

This is on the cosmetic project list; if you want this look don't wait around cause as cool as this is, If it doesn't sell, were going to evolve its cosmetics to a cleaner and improved state.
