Help with tube tester

[Daniel Koenig]

Hello everyone, I am new to the Forum and I have a question about something I just purchased at an auction. I have a allied radio, knight 400A tube tester. It did not have a manual or any paper work with it. Can anyone help with info on how to set it for testing tubes. I have looked online like crazy for info and can't find anything. Thanks for your time. I will try and post a picture of it. Dan

Tried my favorite go-to for old tube stuff. They call it "bama" for Boat Anchor Manual Archive.

They have the model 600, but not this one. Don't know what the differences might be.

Gotta be out there somewhere.

I just checked mine I wasn't sure what kind it was , but mine is an " Accurate Instrument " I paid $3 for it @ a yard sale years back .But it brought back memories my nephew who passed away 5 years ago would sit there for hours w/ an old bag of tubes looking them up and checking them . Thanks for the " Good" memories . 73 and God Bless , Leo
