Recently picked up this flanger. Bypasses signal fine but with the effect on it makes no noise except for a tiny little hint while sweeping the enhance control. Otherwise it's dead silent. I do know there's ~20v on the secondary of the t-former but do not know how to troubleshoot from there.
Some photos and details about this particular flanger...
There's been some sort of modification that looks like it may have been done at the fatory(?) The next couple of photos show an added resistor on the back of the board and one leg of the corresponding resistor moved over to another location. I'm kinda guessing this had to do with a revision, but I'm not sure. Need a little help with that too, please.
Has the MN3010 chip fwiw, and on the inside of the enclosure 10-205P is stamped/molded in.
So where do I start? I have some hobby background in tube electronics but I'm pretty green on this type.
