My model t 40 channel just developed an issue, where when I key the mic all power falls out. So I key it and get 3 watts then in a matter of a second its dropped to .6 watts. Is this a tube issue?

Here is a new to me problem with the model T. I warm her up then key her up and.power drops from 3 or 4 watts to .6 and lower. Is this a tube issue? All tubes are lit up but clearly that doesn't mean a whole lot sometimes. Where should I start my search for the issue??

My swr was through the roof when I keyed up today. I found the wire to look like it was chewed..going to replace with solid 12g and see how it works.

Does anyone know the length of the wire to the ring?

Do you have a link I can follow to check out this variable?
