My OLD Project....... cheap tube audio project!!!
Since I was sick for several months & admitted in hospital.
But............. before I sick, I did several projects already.
holding on hands without funish....... Now I continous it already.
Before I did this project I was considerate how can use limited money for one quailty tube amp? More diyers can afford!
middle range power output, reasonable price, good sound. flexable or said multi-brands of tubes in market for user to exchage.
Light weight, small size, good outlook...... & finally was cheap price.
after my consideration, I did this alrady.
pls see the out look of the chassis.
compare the Nokia phone & chassis size!
Two potted was 0.23mm thickness Z11 silicon laminations 20W PP OPT!
thx

OK,
Although this is a cheap tube amp( Combine pre amp & power amp)
But, Volume Control was very important for it.
Cheap volume control will cause the input data loss too much & effect the sound stage.
A good shielding also importnat for the volume control.
After it, I call factory use PCB with tantalum resistors produce a cheap but high accurancy, low COST & price was most user or diyers can afford! If........ can use it for the standard arts for cheap tube amp will be the best!
take a look for the volume control which use 0.5% SMD tantalum resistors.
