Description

Preamp Tube Adapters

Preamp and signal tubes are more diverse than power tubes in general and have a wider variety of pinout patterns. Many of the standard voltage-gain amps like 12AX7, 12AU7 and 12AT7 have the EIA-standard 9A pinout. These test directly in the Maxi-Preamp with no adapters needed.

For tubes such as 6DJ8, 6922 and 6FQ7, pinout configuration is needed as well as internal components to match tube characteristics with the Maxi-Preamp capabilities. The list on the right provides an overview of the standard stock of preamp tube adapters we carry. They are listed by EIA base and include most dual triodes currently available in today’s market.
