Well, then you found it. Change the caps, the transistors and possibly the diodes in the power supply. The transistors may be good, but they are so cheap you might as well replace them. Check the boards for any broken traces as well. It should work once you get B+ at the tubes. They are lighting up because the filament supply (heaters) is working fine. Those preamps aren't bad. If you can get it running for $50-75 in parts then it is worth that. I wasn't all that impressed with the one I rebuilt, but it wasn't bad by any stretch.
Good luck,
Don
