Title: Pentode - triode switch power tubes
Post by: tubenit on March 02, 2023, 07:32:46 am
Please pay attention to the pin numbers on the power tubes and double check for errors prior to wiring your amp with a pentode - triode switch.  Make sure you are using a proper DPDT switch for this application.


The screen and plate numbers are often different for different power tubes.


CHECK for ERRORS!
