Accessories for your Maxi-Test Digital Tube Testers

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

Description

Power Tube Adapters

Most common power tubes have the EIA-standard ‘7AC’ octal-base pinout. For non-standard tubes, we offer a range of adapters in the list at right to accommodate virtually any power pentode, tetrode or triode. Custom adapters can be made 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
