Last weekend I purchased a RCA 45-ey-2 record player. The changer seems to work flawlessly, but unfortunately the amp has a problem. Once the tubes warm up it produces a loud steady buzz that does not vary when the volume control is adjusted and there is no sound from the stylus. Does anyone have any suggestions or do I contact one of the online repair shops? Thanks for any help.

Did you check the tubes to make sure they are firmly seated? Also, after they have warmed up, you could try tapping them with a wooden pencil to see if it has any effect.

Now, I take it that all the tubes are lit. Though, this does not mean that they are all good. If you know someone with a tube checker, that would be the next step. If not, there is a test for checking the heater continuity with a multimeter, which unfortunately I don't recall.

Here is a link on tubes, a general intro along with identifying a bad tube through visual inspection, hope it helps: http://www.wikihow.com/Find-out-if-an-Electronic-Tube-Is-Good

As for the buzzing, it could be caused by a faulty capacitor or transformer, more likely a capacitor.

Did a lot of internet searching and found several places that will repair my player, but am going to check with fellow recommended by Rich at Rhythm Records in Bismarck ND. When I get it fixed will post a pic.
