Was there a solution to this query?
I have a similar issue. On turn-on, the V5 6LU8 will slowly start to glow red and then the V3 6LF6 (vs. V5/V1 above). As the V3 6LF6 becomes more red, the V5 6LU8 less so. Using different tubes does not change this behavior, so issue is location specific. The upper grid voltage is very low for the short time I left on the amp (~6V): The plate current (~300mA), lower grid (~42V), and B+ (~325V) all look fine (even though B+ is a bit low).
If no solution known, can someone please post test point values so I may track down the root cause? I'll post any solution.
