brief overview  Time owned: 6 to 12 months
I put a set in my Ameritron AL-811. In this application they serve me quite well. With the larger graphite anode of the 572B in the stead of the 811a's tin steel type, these are more forgiving and more durable. Even Ameritron recommends this upgrade with no hesitation. 40w drive gives me about 400w out SSB consistantly. Have a set in the wings but I may never need them. $75 plus shipping for the three from China on e-bay

Have had great luck with these. Thank God for the Chinese, Ha!  Time owned: 0 to 3 months
I ordered, directly from China, a matched set of four 572B's for my 'new' Collins 30L amplifier. They arrived in perfect shape and tuned up with no problems. They run cool and efficiently in this classic amp. Will probably buy a spare set to have a lifetime supply of valves. I highly recommend them; hopefully, you will have similarly good luck! K4SPS
