Accessories for your Maxi-Test
Digital Tube Testers


Adapters are used to interface tubes with non-standard pinouts onto the MaxiMatcher or MaxiPreamp. There are different adapters for power tubes and for preamps. They are small yet mechanically robust components that we have custom engineered for many insert/removal cycles. These units will last for the life of the tester.

Power Tube Adapters
Most power tubes have the EIA standard 7AC octal base pinout. For those that do not, we offer a range of stock adapters in the list at right to accommodate virtually any power pentode, tetrode or triode. We can also make custom adapters for any tube that is not in our stock set.

300B and 2A3 adapters now available!

  • Test directly heated triodes on your maximatcher.
  • Test both Plate Current and Transconductance
  • The MaxiMatcher does not have isolated filament windings, therefore only one 300B or 2A3 adapter can be used

Only $149 each

SocketSaver
The SocketSaver can extend the life of your MaxiMatcher. This adapter is installed via simple hardware into each socket of your MaxiMatcher. Tubes to be tested are then inserted into the SocketSaver taking all the wear of inserting and extracting tubes into the MaxiMatcher. If the SocketSaver becomes worn, simply replace the SocketSaver instead of wearing out your MaxiMatcher. This hardware is strongly recommended for tube resellers or any who are testing up to thousands of tubes.

The SocketSaver comes as a kit with hold down screws and spacers. You can easily convert your MaxiMatcher into a single rugged unit by threading the screws provided in the kit in place of the socket mounts in the top deck.
Only $35

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 active 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.
