A couple thing to check. What is the voltage from the filament -probe to the grid + probe on the 71A with a good transformer? What is it using for filter caps? Ecaps? Film? and value. Does the same half of the secondary go open? Check 71A sockets for carbon tracks or burn marks from pins 2 and 3.

Vol 1-50 admiring the old set and trying to
