8. A 20 watt class A push- pull amp that has some unusual features and an experimental all pentode preamp design of my own
that works great!
Preamp tubes are 5654, 6BH6, 6BH6 - Effects loop tube Decca Radar A2900 (British) - Phase inverter tube JJ ECC 83S -
Power tubes -6AQ5W's or 12AB5's
First switch on left is screen grid bypass capacitor on/off, Knobs from left to right are : 1 preamp gain,
2 triode/ultralinear/pentode operation of tube #1, 3 bass, 4 shift,
5 treble, 6 master vol., 7 effects loop gain, 8 phase inverter gain, last two switches are standby and power.


9. A pair of tube guitar amps built from recycled computer power supply enclosures, transformers from old wall-wart cell phone chargers etc..., and 50's -60's tubes!!
The one on the left uses a 6AQ5 power tube, putting out 10 watts,
the one on the right uses a 6AK6, putting out about 2 watts, both use 6AK5 and 6BH6 preamp tubes.
Both have a front mounted input jack, master volume on the left and a preamp gain on the right, and rear mounted output jack,
power switch, and power in.

10. A class A SE 10 watt combo based on theVibro Champ / Silvertone XL 12 circuit. No negative feedback is used and the tone stack is footswitchable in/out, as is the tremolo. JJ EL84 power tube, 2 JJ ECC 83S preamp tubes,
8 inch Jensen speaker, mahogany 3/4" plywood and tolex cabinet.

11. My idea with this project was to put together from scratch a workable TUBE guitar amp with mostly scrap that nobody wanted anymore. 
You can build a tube guitar amp into almost any package that one desires with only moderate space considerations,
albeit more than a solid state amp would need.  So the sky is the limit with what you want the amp to actually look like.
This amp is incredibly easy to build, being only a single ended class A, a 12AB5 power tube and a 2 tube 6AK5 preamp.
