Time to start getting rid of stuff I know I will never use. Here is a matched pair of PULSE rated 8877 tubes in new condition. I did test both of them on 20 meters with 50 watts drive for about 1/2 minute each to confirm they are good. Date code is 1547 on both of them. $850.00 each shipped or if you buy the pair $1500.00 shipped. Thanks, Terry W6RU. Bakersfield, CA.
