"Our Eico said the 6v6 tube was fine"
First, did you do the shorts test? It's not easy on an EICO, but you can test for shorts.
If it passed the shorts test, it was a short that only occurs with high voltage present. Testers test at approx 150V, amps run the plates and screens at 400+V.
Usually, in 6v6 types, it's a screen short.
