Hi everybody, I have a b&k dyna-quik model 500 with the 510 extension panel. I found a tube chart on line that covers tubes that aren't listed on the tube sheets that came with the tester but I'm having trouble make sense of it. It says it's for the 500 but the layout is different. I'm wanting to test some 6bq5. The black & white example is what I found online. Any help would be appreciated.
