The 6F5P Triode-Pentode is designed for operation in Vertical Sweep Units of Widely Used Television Receivers. The 6F5P Triode-Pentodes are Miniature Devices enclosed in Glass Bulb and provided with a Nine-Pin Base and an Indirectly Heated Oxide-Coated Catode.

2025年2月2日 · Just finished a new stereo amp build using a 6F5P (ECL85) triode strapped with a beefed up split rail power supply and some oversized Musical Power Supplies output transformers. The amp sounds amazing. Despite taking great care in power supply design and layout there is still a minute amount of 120 cycle hum ?
