I know this is not a tube specific site, but I hope your experince will help me here. I just recieved two boxes, there are two more, of about 100 various NOS tubes each from a job site. the lady just wanted them gone, her grandfather was a tech. we're talking 400-500 tubes here. mainly RCA's, GE's and a few Westinghouse. is this the pot at the end of the rainbow?
