Im trying to make a 12dw7 mini amp for playing my electric guitar at acoustic outdoor jams
Any input is appreciated, Thanks~ Austin

The whole point of any of this effort that I spend is to gain as thorough of an understanding as I can. I guess the easiest way (to answer my own question) is to simply buy 100 rechargable aa batteries and sting them all together in series for the b+ power supply. I already have 4 18v drill batteries so maybe I will use those. Li-ion would be obviously the best but money is also a factor. I am trying to build an amp that runs on batteries so I can walk around with a tube amp running on batteries that can be my guitar amp. The amp is needed for acoustic jams because I don't like playing acoustic guitar and at drum circles to be loud enough to be heard. Next after this I plan to build a linear amplifier for short wave radio or cb that runs on batteries. If I can figure out a dc coupled amp design, then it will be linear from dc to in the mhz range and I could maybe even use the same amp for both purposes which I think would be really cool. Have a guitar amp that could also function as a linear amp! solar panels! I bet with cathode bias to compensate the change in volts when the clouds come the solar panels could make enough juice for b+ without any batteries helping at all except for filaments!http://home.comcast.net/~stphkeri/Bates_DirectCoupledCathFollower.pdf
this amp only needs 53 milliamps for b+, a decent battery source could run for days on that little of a drain. Years ago battery powered tube radios in cars even battery powered tube walkie-talkies were very popular as I understand! I know I can do it and that it will be awesome. Thanks, Austin
