    I have a Hickok 800 tube tester. I also have a 6AR5 tube I need to test. The manual and spinning tube lineup does not include this tube in the mix. Tube came from a vintage Akai M8 reel to reel. Appreciate any guidance on the proper settings for this tube in this tester. Thanks for looking.

    MRL -- The tube has a pin out equal to that of a 6AQ5 -- except that the 6AQ5 uses BOTH pins 1 and 7 for a G1 connection, where as the 6AR5 only uses pin 1 for G1, with pin 7 showing N/C. And, the characteristics of the 6AR5 are identical to that of a 6K6GT. Therefore, if you can arrange the socket terminals to pin-out for a 6AQ5, but set the tester up for the characteristics of a 6K6, you'll be good to go.

    I hope this helps!
