Dumb question, but...

Probably a dumb question, but...

When looking at the schematic for a Quad II power amplifier, there are three secondaries on the mains transformer:

310 - 0 - 310

2 x 5V

2 x 6.3V CT

As the 6.3V is CT, does this actually mean each individual wire from this point is actually 3.15V?

Many thanks,

Yes, 3.15VRMS, under load. Unloaded, it will be higher.

Thanks Sy

There are two 6.3V windings one for the heaters and the other 6v3 is switched out to the control unit. The CT is just a common line.
