Yes, 5Y3, new production Sovtek from Hoffman Amps.
Input voltage = 124vac
Red = 352vac each
Green = 3.4vac each
Yellow = 0vac, ?? it reads 435vdc each, same as at C1
The spec for this PT (from AES) is 120vac primary, 325vac secondary, 6.3vac green, 5v yellow (AC or DC?). Is the 352v secondary reading that I get higher because the input voltage is higher than spec? I totally don’t understand what’s up with the yellow pair readings… Help!
