Hi guys!
Thanks for the help perviously.. I've soldered the my MadAmp A15 MKII Deluxe complete today, and all measurments so far has been good - except the Primary side of output transformer.
The secondary side (4, 8, 16)ohm is OK, i just measure the pins against the 0 at the transformer, and its all ok.
BUT.. I cant seem to find out how to measure the primary side.. ?
Which pins to measure, and against what? The manual says that the primary side should be 500ohm.
I tried measure pin 6/7 against 0-ohm and it gives me resistance-bumb.. It runs up and down from 0 to 8-9Mohm and then settle at around 65kohm.
Help please! This is the last thing left before I can plug the tubes and try the amplifier.
