    Ampeg BA115T Transformer Problem

    I picked up this Ampeg BA115T For free on Saturday. It would not power up. I installed a new fuse and it powers on but it’s obvious from the hum and buzz that the transformer is bad. Seems to be a common feeling in this model and the transfer replacement part is more than it’s worth. I took it...

    Ampeg B100-R transformer hum - how to eliminate?

    I have an Ampeg B100-R that has a steady low volume hum. Reminds me of cheap flourescent light fixtures. The volume of the hum doesn't change with or without bass plugged in, and doesn't change with change in gain or master volume. For a long time I thought this was some kind of grounding...
