I am working on a K250-1 for a friend's grandson. I have wired a 3 wire cord. I have swapped the working and intact polarity switch for the broken power switch. I have removed the wiring to the polarity switch except for the green wire for the bulb terminal located at the end of the switch which remains. The other terminal goes to ground. The amp is working fine. I have 335 replacement bulbs which I understand are 28 volts. However, I measure 40 volts at the bulb terminal. Is this normal? If so, what keeps the bulbs from burning out? Thanks in advance. Jerry H
