Re: Crate BT50 Bass amp cutting out with high input.
Sometimes an amplifier's preamp can't handle certain signals/frequencies at a high gain, so they cut out. Bass guitars are especially prone to giving such a strong signal. I bought an older, nonworking bass amp recently and fixed it just to find it had the same problem. Best solution is to put a low ohm resistor at the amps input, but if you turn your guitar down to half volume it'll have the same effect: should prevent it from cutting out.

the towing procedures will, be in the user manual
depending on the trailer weight( less than 1 ton) it is permissible to tow in over drive and for a trailer without load levelling ( stabilizer bars ) 100 klms would be an ideal speed
5th gear is a direct drive gear ( input and output shaft connected as one) and the idea of staying in 5th gear reduces the load on the gears and bearings
250 kg is sitting on a horizontal surface. Hence, the ground or the horizontal surface is exerting 250 * 9.8 = 2450 N to support the crate. Now, coeff is 750/2450 = 0.306 . The force you have to exert to move crate depends on how heavy the crate is. If crate is heavy you will end up exerting more force. The ratio of the forces provide the coeff of friction.
I don't know how you know the tubes are good... It is possible they are microphonic... try tapping them with a pencil (only need to worry about the smaller ones).
Beyond this look for cracked circuit board or bad solder... especially near the control pot leads. This is a common problem. Look for cracks near the booard mounting points.
guitar amps are all set to a low Z resistance configuration. wich are made for guitar only. make sure you are using the right cables.
you need sheilded guitar cable not unshielded speaker cable in many cases these cables look exactly the same. look at your cable look for the words speaker or instrument. you need the instrument cable. if you still have that problem. then you may just not be satisfied with the quality of the amp it self.
turn that ****** on and get a can of freeze spray. coming and going type issues is usually related to a failing electrolytic capacitor. there may also be a bad mosfet, rectifier, diode, etc. i would be suspect to caps. schematics probably only available thru crate and you have to pay a couple bucks, but trust me its worth the couple bucks spent and having it on its way than wasting hours online not getting anywhere. by the way i checked my sources and came up with nada. yostamplifier.com
Several things can effect the quality of your files. 1. Check your headphones by comparing them with others. 2. The file quality may be too low, you can test that by getting a higher quality MP3 file and comparing the two. 3. If you are creating the MP3 files yourself, be sure to watch the sound recording level. Allowing it to stay in the red can produce distortion while recording ay too low of a level can result in low voulume as well as possible distortions. If none of these correct the issue, you may need to replace the player.
