My Crate blue voodo amp head

Im not an expert on amps but im guessing that the tubes in the amp are broken. I know its not the fuse because the lights will turn on but no sound will come out. This is an old amp and I saw the advice you gave the guy on the fender amo, so i thought maybe you could help.

Hi...

1st off , check the connections from the head output jack to the speaker cab. If you can get hold of a meter , check the continuity on the cable (center wire to center wire , ground wire to ground wire) both should be about 0 ohms.
Do you have another speaker cab you can try>?

You might have a speaker fuse internal on the amp too OR a secondary fuse on one of the power supply lines

    see if the tubes are "lit" . There should be some glow action in the tubes when it's fully on.

Have a Crate V50-112.Have had it for 1 year. Replaced tubes 2 weeks ago, turned amp on tonight, started to play, amp went dead. Checked fuses, they're good. Any ideas?


Check for bad tube... it HAPPENS that brand new ones fail... USUALLY if they last 50 hours, they will last for the expected life. The bad tube would likely NOT be the main power tubes, as the amp would still run on one cylinder...

I have an old crate blue voodoo amp head that wont work


Good day sir, changing the tubes won't solve the problem, sad to say it but you may need to bring it to a veteran technician, that knows tube amps. there are simply lots of things to check for. hope this helps, thanks

Crate bv120.no power or sound..no lights..f6 fuse has 160 ohms...


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.

Crate tube amp will not power up but cooling fan tries to run


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.

Crate BV120 too quiet


Have the tubes checked when good and warm.
Check for any leacking capacitors.
Check all solder joints are shiny any that are dull try to reheat and apply solder.
Good Luck
