Thanks for the warm welcome, the response and the speaker insight!  I am in process of repairing the cone, however, it is becoming brittle and cracking with every touch.  I watched a you-tube on re-coning.  I am considering doing this myself, however, not sure if i want to try unless I am out of options.  Not having the proper electronic equipment my validation of operation will be with output sound will be step one, followed by very high level troubleshooting with a multimeter. Good news is all tubes glow and unit powers up.  I know glowing of tubes is just the heater, not a 100% accurate method of operation. Stay tuned and thanks again.
