I have a Marshall 9005 stereo power amplifier meant for guitar. It was made in 1990. It stopped working around 1994 and I never bother to figure out why.
After 18 years in storage, I pulled it out but I'm not really interested in trying to fix the amp. It uses circuit boards, the wiring and solder jobs aren't that great, lots of flux all over, etc. Not to mention, I don't have any EL34 tubes for it and I don't really need a 100 watt guitar amp.
I want to pull the transformers out and sell them to fund another project. There was never any smoke or anything when it stopped working. The tubes would light up, but it just didn't make sound. I'm wondering how to determine if the transformers are any good or not. Can I just measure the primary/secondary impedences and check for shorts with a DMM? Thanks for your help.
