This is the bare PCB of a tube regulator board with reference to ANK M2. M2 regulator board is used with ANK L2 and L3 phono boards.
The design uses a 6X5 rectifier tube and a ECL82 tube.
PCB dimension : 132mm x 152mm
PCB thickness : 1.6mm
Copper thickness : 70um, Gold-plated surface.
Input voltage : AC300V-0-300V 50mA, AC13.6V - 15V 1A
Output voltage : HT section -- +260VDC+/-3% with default resistor divider value. The board has the provision to use a trimmer pot instead of the fixed resistor to adjust voltage to meet user need.
Filament section -- dual +12Vdc 500mA ( can be configured to +6V when 6V regulator chips are used instead).
