20 Most Recent Ampeg BA115 1x15' Bass Combo Amplifier Questions & Answers

Did you check the fuse? and power cord is good?

With no leads connected to speaker, use an ohmmeter to check resistance of speaker. If NOT less than 10 ohms, you be replacing the speaker. Also look for loose speaker wires. More than that and is will require repair in the shop.

Failure, likely in the power amp causing overloading of the power supply and dragging one power voltage into the range where the ripple voltage gets to the speaker. This is very ******* the speaker as it gets high DC current and can burn the voice coil. Slight chance that a filter capacitor has failed. In either case repair is needed.

Here is your schematic. Likely the fried components are visible.

When repairs have been done, start this up using a 100 or 150 watt incandescent lamp in series with the power cord to act as a fuse... There likely are several components blown and you may not get them all the first time. The lamp acts as a resettable current limiting fuse so you don''t blow out what you just replaced.

Hello,

Sounds like a repair shop job to me. Inputs on a amp have resistance thus there must be a issue inside hence 0DB to 15DB if you go higher well that input thus would not work anymore.

Repair shop would be your best bet for this amplifier. Quick Fix would be unplug it and plug it back in and praying it resets but that won't happen.

hope this was of some help, if not I am sure others will chime in with there 0.2 cents.

Duberney, there's just no way of telling anything regarding a unit's condition without examining the unit, however, what you're describing sounds like something in the chassis (around the power sec) is loose. Duh. The procedure to chase that sucker down requires a technician to fool around in there with the power on, so it's really not something that I would recommend an amateur do. I'm sure you would have no accidents - but it's just plain fun to see other people get electrocuted. Send me your city - I'll find you a tech.

The VT 60 was made in the USA and was a very good sounding amp introduced by SLM (St. Louis Music) in 1989. There are three channels: clean, crunch and overdrive. You should be able to obtain a decent dirty using crunch channel but if I remember well you MUST have the dedicated pedal to switch channels and reverb.

Sounds like you have a loose connection. Try re-soldering the internal connection. and check the wire for breaks. it may be the cause of your intermittence. Good Luck!!
