We use and recommend Electro-Harmonix Gold Pin for all Ultra Low noise critical applications.

Quantities are sold with Matched Sections.

Please note that this tube can not be used in place of 6DJ8 or 6922 tubes in other pre-amps; it can only be used in equipment that is designed for it.

The 6H30 tube type is generally not compatible with 6922 and ECC88 tube types.
