| Does this amp have a problem or is it OK to buy? In addition, when the CD player is on, and the input selector on the 302B is set to other than CD (such as AUX), turning the volume knob has no bearing on the hum level - it stays constant at the barely audible level.River251 04-24-12 | |

| 3 preamps with transformer hum, DC on the line? The isolation transformer (a Tripp Lite IS350) did not change anything.Sbrownnw,If you can't send it back, you might try feeding youroppo BDP-93 player from it.Back to your preamp..... What do you have that thing setting on? Would that be working ... | |
| 3 preamps with transformer hum, DC on the line? An isolation transformer will not pass DC voltage. If that were the case the output transformer of a tube amp would not prevent the high B+ DC voltage, that is fed through the primary winding of the xfmr to the plate of the power tube, from passin... | |

| 3 preamps with transformer hum, DC on the line? DC on an AC power line is highly unlikely unless you live in the third world.04-04-12: Dhl93449Not true. You can easily check this with a DVM.
