Hi, I'm building my stereomour, and when testing terminals 20 and 19, I get 170-171 volts AC. It is slightly higher than the 161 AC +- 5%. About 5.5% to 6% higher than 161. I checked over my solder joints and reflowed them, and I still get the same voltage. Would it be safe to continue building since it's only 0.5-1 percent higher? Thank you.
