Bugera V5 Schematic?

[cebreez]

Okay let me make this easier. Can someone point me to some good input circuits for guitar amps... tube or solid state. I know just enough about electronics to be scary. All of the tube amplifiers I've seen are basically the same animal. More power= more tubes= more bias circuitry= more tone control circuitry... and so on. What im trying to figure out is the best input circuitry to stoke the fire in the belly of the beast. Eventually what I want is a fantastic little practice tube amp that wont cost $1000 dollars or even $500 for that matter.

I'm not sure what you mean by input circuits. Do you mean preamp circuits?

The Bugera V5 is a fairly simple amp. One 12AX7 preamp tube and one EL84 power tube. In this regard it is probably similar to the Valve Junior or Blackheart Little Giant.

It has reverb built in, but I bet it is solid state driven as there aren't enough preamp tubes for tube driven reverb. It also has an attenuator to get crunch at lower levels. The reverb and attenuator add complexity.

My 'net research showed that Behringer is pretty tight with their schematics.

What exactly are you trying to achieve by rebuilding the Crate amp? High gain? OD at lower volume levels?
