The 42-380 should have an 80 rectifier. 6X5s were in other 1942 models, possibly you have an undocumented variant OR someone has "modified" it.
The 6X5G tube had a bad reputation for internal shorts that would fry other components in your power supply circuit, including the power Transformer. STRONGLY recommend you replace it with a 6X5GT or metal variant.
