Don probably gave you the correct answer, he has consistently good advice.
You might though want to also check your Astron, if it is one of the ones with adjustable current & voltage, Mine is the VS-35M. The adjustment knobs are easy to bump and unexpectedly change the voltage or current output. I've bumped mine before and caused my K3 to shut down unexpectedly yet the K3 was lit up just fine. I now have a piece of tape on the knobs so it won't happen again. 73, Gary KA1J > In the RTTY contest, my K3 is turning off the 100W amp. > > I set the FP Temp to 19C and the PA to Nor.
