William thats what I found also. Now you have to get it into the tube. To the comment on heating. Thats sort of how Frankenstein works 5060 tube in a 5061. I designed a DC oven controller and run the oven hotter. I now speculate the reason they ran the ac oven was because DC interferes as a magnetic field. The signal is noisy but locks always. This tube is so weak that only through more amplification an external meter and magnifying glass do I find beam peaks. But they are there. Talk about a pain to tune for. By the way to prove that theory I need to build a AC oven controller. Sort of just haven't gotten there. ??? For really smart folks. Frankenstein runs slightly fast and I can see this. If the Cesium is hotter then the specified temperature I suspect the lines slightly move. Everything will lock but its not correct. Is that a reasonable answer? Thanks Paul WB8TSL
