If it is working there are a few ways to keep it working. The original 6X5 would develop a heater to plate short thus grounding the B+ resulting in the winding burning out. I replaced all the 6X5s (all 4) with 6X5WGT which is the mil spec version. Ratings are the same but structure is stronger. I also use a variac to power up the set bringing it up to 110VAC. The input range is 90 - 135 VAC but why take a chance. The set works just fine. The output voltages in the manual are for 115VAC input but modern line voltage is usually a bit higher which will result in higher secondary voltage. I've used this method for the last 15 years without any problems.
