Matched set of 6146/6146a (2) and a 12BY7 OR a 6CL6 (please specify which ONE you want) driver tube. Test better than new on my tube tester and should work great in your ham rig. I have many sets of these available so you may not receive the exact manufacturers shown but rest assured that they have all been tested as new or better on my tube tester minimum "new" reading on the charts. You can be assured these tests indicate a tube that tests new or better on my tube tester. How to tell whether you need a 6146/6146A or 6146B (courtesy of K9STH and muchstuff.com/6146.htm) 6293 is a heavy duty type 6146 has a much heavier plate, and will outlast a 6146 five to ten times. 6146B/8298A is not a direct sub for 6146 or 6146A. Rated at 120 watts input. It requires different neutralizing, and over time the neutralizing may change and become impossible. May try a sub but watch carefully for a long time. If it does not neutralize – pull it. 6146W may be either a 6146/6146A or a 6146B. Depends upon the date. If before 1964 a 6146W/7212 is a 6146A/8298. If after 1964 a 6146W/7212A is a 6146B/8298A. Can be either if dated 1964. In preferential order for 6146 type, unless the gear is designed for 6146B: 8298/6146A or 6146W/7212 dated prior to 1964, then In preferential order if gear is designed for 6146B: 8298A/6146B or 6146W dated after 1964, then the above 6146 group may be used with the limitations as last choice. ******************12.6 Volt filaments ************ 8032 is commercial and same as 6883A. 6883B same as 8032A same as 8552.
