Little update. Installed new power transformer and noticed when input from variac was at household voltage of 120 volts, voltage at primary was only 90 volts.
secondary to rectifier plates only 364 volts instead of expected 550 volts across the secondary winding. Eventually started removing tubes one at a time and with each removed tube things looked better. With 6 of the 9 tubes removed finally started to see things looking normal. 115 volts at primary and 552 volts across the secondary rectifier plate winding. So with all the original caps still in place will start the process of cap replacements. Was hoping for at least a little life from the speaker but as of yet, silence.
