20 Most Recent Crate Blackheart BH15H Handsome Devil Guitar Amp Head, 15W All Tube with Attitude Questions & Answers


did you change out the fuse? could be a tranny going south. if you change the fuse and you still get no power, then you have a fried power transformer. they are relatively easy to replace. look on ebay . get the numbers off of the existing one and start web searching. something will come up. if not email me on my contacts tab in my website yostamplifier.com we can troubleshoot. you should see the custom blue voodoo i built and gave to my little brother.

Yes.
Are you saying that the only indication that it is running at all is that the fans are running? So the tubes don't light up? No indicators on the front of the amp?
Power supplies that provide multiple voltages, which your amp has, can provide some of the voltages while having a problem that prevents them from providing others, all while not blowing a fuse. If you are not confident in your ability to work on a piece of electronic equipment that has 120VAC coming in and at least 175VDC or more present inside it, bring it to a service center.
The good news is that it is probably not horribly serious. Problems like this can almost always be repaired in a cost effective manner.

Power supply capacitors failed. This is a common problem with 1990's crates, also the power on "POP".

There is a short somewhere, check your wiring and solder points.

If sure that power is reaching and getting into unit, then confirm that a signal is also reaching unit. If both are positive, then your gear is FUBAR if signal is going into correct input.

1. Sounds like it's the input jack., but it could be the volume knob. Have you tried turning Gain1 and Gain 2 or the Clean Channel volume? Try them first when you're plugged in to the jack on the left , then when you're plugged in the back. If none of these work, it's most likely the preamp. 2. Even if the preamp is shot, there's a quick fix - get a guitar preamp or an effects pedal - they have volume and tone controls. 3. Finally - many pros just plug into the aux jack(on the rear panel) and control the volume and tone through their instruments. Hope one of these works. Good Luck.
