Question on Impedance switch layout versus Metro instruction
Posted: Sun Apr 22, 2007 7:33 pm
Guys,
I was about to sodler in my Output transformer taps to the impedance selector and found a discrepancy from the picture used in the 100 watt instructions and what the switch really is. I verified where the switch contacts are made, you can feel when the swtich closes on these spades contacts.
As you are looking at the spade side of the switch from the inside of the amp the Impedance contacts are 4 ohm far left- 8 ohm middle- 16 ohm far right all on the lower half of the switch.(top three not used)
My wiring for the C1998 1.5 inch core Dagnall Clone from George shows these lead Brown-common, Black-4ohm, Yellow 8ohm, Green 16 ohm.
Is the above correct?
The 100 watt metro instructions show the impedance contacts to be:
16 ohms far left, 8ohms middle, 4ohms far right according to the picture.
Which is correct? The color code he listed for the tranny wires is correct just not the picture. The image is not reversed because the picture shows the speaker jack to the left of the impedance selector.
I just want to make sure the layout is correct before I cut these on the correct routing.
