I have 5 solid state rectifiers having the same base as the 872A rectifier
tube. They were all made by SEMTECH and carry the number STR4B32. These
are 2 inches in diameter and 7 inches high. Four of them are smooth sided
(#7505 and 30043 on them); the other is "finned" and carries the number 7314
on it. I tested all of them by running 300 volts through each way and they
passed it in the proper direction. These look new but I am offering them as
used. All 5 for $75, postpaid within the US.
Thanks and 73,
George
