Good Evening All, I came across a model 240 a week or so ago at a yard sale and picked it up without even asking if it works because of the price. Once I got it home and hooked up, I discovered it was blowing the main fuse on the back of amp as soon as power is supplied. I had enough brand new...

Hello to everyone. A couple of days ago I stumbled across a big one, the 9001. I’m embarrassed to say what I paid but it was pennies really. For the price, I didn’t even ask if it worked. I got it home and have it a good cleaning, cleaned pots with deoxit and let it dry over night. Next morning...

I picked up a SX-440 a couple of days ago for 10 dollars. After cleaning everything including deoxit on the pots, and replacing bulbs, I powered it on. It came on and bulbs worked, however that was the end of the good news. I get no sound from speakers or headphones. There is 110 volts at...

hello all. I tried this post in Kenwood forum without much response so I thought I would try here. Picked up a KR-9400 for a song last week. I hooked it to a DBT first and it showed no shorts. I powered on but I got no sound including headphones. I have checked all fuses and ground wire to...

Hello all. I could use some help from those who are able. I have a 2275 that I picked up very very cheap. Cosmetically it's minty, but the insides need some attention. When powered on, protection never comes on. So I started looking around and on the right output board I found at least part of...

Picked up a KA7100 week or so ago. It worked fine for a couple days. One morning I turned it on and it blew a fuse. I replaced it and it did it again. F3 fuse - 250v 4a. I was hoping someone smarter than me which is most of you, could advise me on where to start looking. I'm quite comfortable...
