Internal power cable for 6J1 tube preamp

This new internal power cable is designed for the Alloyseed 6J1 Hifi stereo electronic tube preamplifier board. It connects the finished preamp module to a power source inside an audio chassis. The cable suits builders replacing a worn lead or assembling a custom valve preamp stage.

Fixed pin-out and voltage limits

The cable terminates in the connector pattern required by the 6J1 board, so it cannot be adapted to other preamp modules without re-pinning. Its insulation and conductor gauge are rated only for the low-voltage heater and high-tension rails specified by the original design. Builders needing different pin spacing, higher current capacity or shielded runs for noise-sensitive phono stages must source a different harness.
