McIntosh MX 113 Preamplifier

[OldStuff]

I thought I would get my Dim light and check my preamplifier. When I turned it on the light stayed dim almost off, when I went through the different inputs, I noticed that FM would light up my bulb a little maybe 20-25%. What could cause that? Maybe a capacitor?

I guess they shut this forum down, To bad, it used to be a good place to go for information.

I would suspect that the reason is because when you go to FM, you turn on the tuner circuitry, which will draw some additional current.

Thread 'A word about asking for help'

Mar 18, 2019

I realize that this is the age of instant gratification but most of the techs and others who post in this forum have actual lives. So when you post a question it's helpful if you be as specific as possible. Also it may take a day or three before the person who can help you comes along. So be patient, courteous and you will receive an answer. It may not be the answer you want but it's the best we can do here. Also MACKIE1975 reminded me that pictures are very essential either of the equipment or the circuit


Take care.

It is a shame that people come here, contribute little or nothing, ask for help and then post a snide remark about our forums when an instant reply doesn’t come, then disappear again. OldStuff never came back and didn’t even see Bob’s reply less than 24 hours later.

We’re a helpful bunch but we don’t all live on this forum. I wish that they’d all read this sticky, maybe should be a requirement before you can post but a little courtesy and occasional thank you goes a long way.

If you do come back @OldStuff, (“last seen Thursday at 3:59pm” from his profile) feel free to ask questions and we will try to help, but it might take a day or more.
