In Reply to: I just bought a B&K ST-140 for $4. I have a couple of questions about it. posted by The Reverend on April 10, 2007 at 11:36:12:
...very well regarded amp. If you do decide to power it up, I'd use a pair of speakers that you don't care much about as a first test. Also, I would check the fuses closely; even if there are fuses in the fuse holders they might not be the right size.Reminds me of the time I saw a very dusty grey box in a pile of stuff at a thrift. It was an H/K 450 DC in perfect condition; a real sweet music maker.

How would I find out if the fuses are correctly rated? I am honestly assuming that they are, at 4A, 250V. The one in the left channel is there and intact. What would cause a fuse to blow in this situation?
...the amp is working fine; which is great. Usually the fuse rating is marked someplace by or on the fuse holder, or on a tag on the back or bottom of the amp (I've also seen it inside the case, sometimes on a small schematic). If the fuse in place is of a higher rating than it should be, the amp will not be adeqautely protected. If the fuse in place is of a smaller rating than it should be, the fuse will be more likely to blow. An old fuse of the right size can also get worn out from stress and blow. A visual inspection does not always reveal a faulty fuse.If everything is working well, with a good cleaning of deoxit, a touch of progold, and some good wires, you should have a sweet and well regarded amp (for $4 ; ) What are you using as a pre?
I am using an NAD 7000 for the pre.Believe it or not, the connections are totally clean. I don't have any deoxit, but heck, I could go get some.
I am thinking that I will just pick up some blue-jeans cables to connect the pre, but I don't know what power cable to buy for it. I don't want to break the bank on cables, I just want to hook it up and give my guitar amp's cable back to it.
I can't believe someone would get rid of something like this! If the only problem was a blown fuse, well, wow, I just bought an amp for $4.50!
...an integrated amp with pre-outs.
