Hey all, First post! I've gleaned a lot of valuable info from many folks here, so thank you all for your generosity. I finished a 5F1 build last month (Boothill, everything was great, thanks Dave!). 15W Classictone OT to a 4ohm 10" Alnico from Weber. Sounded really nice. That is until my temporary cabinet-less setup pulled the speaker tabs off the speaker without me noticing - I fired up the amp and it ran with no speaker load for probably half an hour before I sat down. Nothing noticeably fried, though a toasty smell permeated the space and I've got nothing but hum with no effect from the volume pot. Replaced the 6V6, no change. Before I accept the reality that my OT is cooked with the keps nuts hiding under the turret board, are there any other components I should test that would have fried first? Capacitors in the power section? Otherwise I'll just run robrob's startup procedure again to try to pinpoint it. Please enjoy my avatar poolside chair shrine to Uncle Doug's grill cloth hack. Thanks!
