Ver A: PCB standard version, power transformers 96 * 50, 66 * 36 output transformer. When you want to take the time to change the machine, the advantage of low noise.

Ver B: welding by hand upgrade version. Manual welding, preferred audiophiles, the output transformer switch to the higher end of the 76 * 40 output transformer. When low-frequency dynamic playback is good, control and strong, it is more powerful.

Ver C: PCB upgrade version. PCB, output transformer is 76 * 40 output transformer. When low-frequency dynamic playback is good, control and strong, it is more powerful.

The price is NOT included the tube cage cover. if you need the tube cover, plus extra $20 USD to get it.
