Good Day All.

First post here, So, I took an existing toroid, It said 168va 30-0-30Vac I removed one of the windings completely and then rewound the other one, calculated I should be close to 12-0-12Vac, sure enough, I measured after the rewind and was sitting pretty at 12.2Vac per winding. This is where I am now left scratching my head.... If I take 12.2Vac x 1.41- 1.2V diode drop I get 16.02Vdc on the calculator, when I measure this with the meter at the caps I only get 15.48Vdc...... The rectifier is a repurposed RS1505m and I have 2 x 4700mfd @63V..... Does this sound right? I do not know so would rather ask.

Thanks in advance.
