Nace Pro 18 head about 4 to 5 years old. Suddenly the sound cut drastically , sounds tinny with little volume.
The Small tubes EL 81 and 83 are unlit and barely warm to the touch. I don't see any evidence of burning. No obvious burned filaments or black on the glass. I replaced these a couple of years ago. The EL84 tubes glow and are HOT. ( don't ask).
If the 81 and 83 are replaced should I go ahead and replace the 84's?
Suggestions and experience appreciated.
Thanks, Pat
