Product Description

Introduction:

The PRT05A is based on the U.S. famous CONRAD JOHNSON CL circuit. Use double independent design, Physically left and right channels are 100% separated, Independent hierarchical grounding.

PCB integrated high voltage regulator circuit (260VDC) and filament regulator circuit (6.3VDC)

Note: In the filament power supply, the design tube is 4-5 feet in parallel and 9 feet are grounded, so it is only suitable for 12V power supply tubes (this version is only suitable for 12AX7, 12AU7, 12AT7, 12AX7 is recommended)
