pretested used tube stock
 

Working on tvs/radios...etc since the early 70, s in my basement shop for a large part of my career (made more working for myself)(tough to keep new stocked tubes) i used pretested in tvs or whatever used tubes i knew were good in a set.saved me a LOT of trouble.i would recommend that any tube set every member has in this forum,stock used tubes tested on a tube tester AND tested in your known workining (or once you got it working) sets. A lot easier. Maybe this should be a stiicky post. RonL
