Check for negative voltage on the grids of the 6A3's. Should be about -60v. If you don't have it on both grids Check the center tap of the driver transformer (92) If you got it there replace 92. Check for plate voltage on the # 42 tube. If is is low replace (92) Also try removing the #42 and watch the b+ to see if it drops as the set warms up.
