Hello all, new member but long time stalker. My go to amp, a beast of a 2x12 Thunderbird has ceased functioning and I'm calling out for help. I have never been able to determine what version Thunderbird I have as there is some contradictory info on various sites. It appears to be 1969 or 1970 version ll however the photos I've found are not dead on. The power transformer is no longer putting out any voltage when applying 120 to primary so I'm assuming it is kaput. My Thunderbird is the tall 2x12 Concertos, non-master volume, 2x7591, solid state rectification, point to point wired separate pre-amp and power amp. If anyone knows what modern power transformer will work or the voltages that need to be provided by the transformer I would be in your debt. The only schematics I've found for Thunderbirds either featured tube rectification or 6l6's so no help.
Thanks in advance.
