Amp Kit - MOD® Kits, MOD102 guitar amplifier

Question:
I built a 102+ kit and it worked great for several weeks. I could not be happier until it just quit. I started down the troubleshooting guide. HV DC voltage is 282 and B1 a paltry 7v DC. All other voltages down the list are too low as well. I do not know how to correct this. I have re-tightened all grounds and checked solder connections. Please help! Thanks
