Test Point Quest...

When you see one of these Fender Schems, and they show a "test point" inside of a circle, with a specified voltage (often in miliamps) is the voltage:
1. Measured from ground.?
2. Is this AC or DC.?
Thank You

Well if you refere to for instance the Blues deville schematic it says that all voltages are reference to ground and it seems that all the signal level voltages are in circles and say vac within that circle.
All the other dc or AC voltages that you will find within the amp you just have to know what your are doing and what to expect at ant one other place you poke your voltmeter probe to!
The schematic even tells you what signal level they where driving the amps input with to read those signal level voltages in the circles !

Thanks Steve -
Did not even look at the Deville Schem.
Working from a laptop right now, and I cannot magnify anything.
Will look at that later when I am on the desktop, and I can enlarge the schems.
Thank You
