We can Declare the Value of the Order as Customer's Remark!!!
this is the upgraded version of RFTLYS A5 PLUS
1. pure gall, pure hand-made, the whole machine with scaffolding welding.
2. With fine remote control, transistor super-linear connection conversion
3. A5 total of 8 tubes, of which 6N9P and 6N8P each 2, respectively, as the former input and inverting drive, and amplifiers are used in four KT88, in the super-linear connection output 45W × 2, the transistor output 25W × 2. A5 The EI power transformers used in the amalgamation are made purely by hand.
4. Bias bias adjustment device can be designed according to the level of the table to fine-tune the power value of the working value of large tubes in order to achieve the best working conditions to facilitate the players at any time to monitor fine-tuning or replacement of different brands of tube adjustment.
5. Tube cover behind the transformer cover, still using three large metal transformer shield, the power supply and output transformer shielding.
6. Output by two special process around the system, high-quality wide-band EI output transformer.
7. Volume control potentiometer using Japanese ALPS motor drive products, and comes with exquisite remote control, in addition to control the volume and source input selection, but also for super-linear and three-stage connection.
