All pins and wires are connected properly. I send power tubes back. I will rapport you back about the voltage when I get new ones. Thanks for your input. It's nice when you can found people ready to help.

When you get your new tubes and before installing them set the bias voltage on pin 5 to -42 volts in this way you will not harm the new tubes in any way and then when the amp has been on for 5 minutes you can set the bias current from the test points.
When I die, I want to go like my Grandfather did, peacefully in his sleep.

Hi everyone. Ok , I was on the phone with guy who sold me the el34l jj tubs and after testing them, hi said that tubes are ok . Ok or not? Before I send them I try set bias, in ceriatone we have slot for every tube socket for bias ok. Now. 1 tube reading was very of 51 mv where another three have 37mv. So I swap the one with 51mv in to another socket and tubes show me 50 mv . Now is my tube is bad or this guy talking shit. Thanks for any input.
