I was testing a 5V4 the other night. I was suspicious of it because it came out of a Collins 32V-3 with a blown LV transformer. The 5V4 was the LV B+ rectifier. The 5V4 yielded the proper meter reading when the RECTIFIER button was pressed. When I ran through the SHORTS selection on the switch, all short positions caused the NOISE lamp to stay lit. I thought AH HA, the tube is shorted. I put in a NOS 5V4 and got the same reading and short response. Now I"m wondering if the TV-7 SHORT circuitry works with the 5V4 tube or do I simply have an old shorted tube and a NOS shorted tube.... Have you guys tested rectifiers for shorts on the TV-7?
