Just finished the standard Quickie 1.1 and ran through the voltage checks. 'A' side is perfectly in line with where it should be, but the 'B' side reads significantly higher.  Terminal six reads roughly 38 volts where it should be 29 volts, terminal seven is correct at 38 volts, terminal nine is 7 volts, and terminal C is 8 volts.

Basically, terminal nine and C are roughly twice the voltage of the Alpha side and terminal 6 is reading about 10 volts over.  I moved the tubes to the opposite socket to see if it had any affect and it did not.  Any ideas on what to check for?  Thanks.

I think you may have swapped the 1.07K and 470K resistors.

Caucasian Blackplate,

Even with the magnifying glass I can't tell them apart, but I checked the resistances and you are right on the money.  Thanks for your help.  Will fix it and see what happens.  At least my soldering has improved and that isn't the issue this time:)
