Maybe some of you recognize some of these or Co names. My grandfather Jack was "W3GS" also SCM (Section Communications Manager) for the ARRL Eastern PA section in the early-to-mid 1930s. Later on Chief Engineer for Herbach and Rademan, and El-Tronics, and then President of AEL American Electronic Laboratories. I admired his gear and went on a few transmitter hunts as a young teen. Funny he would only talk to me over dinner in Morse Code .... .- .... .- dit dit dit dit dit dah :) Sorry to go off thread, but it peaked my curiosity. My grandfather passed when I was young, and he inspired me early on with all of his equipment and tubes! |

But, I'm sure most here know that Dennis has quite a history and interest in ham radio himself. |
Thanks to this thread I just ordered some Psvane cv181 grey glass input tubes. Ouch, said my wallet.

Look for W4USR on the airwaves. But you better know your Morse code since Dennis typically only talks in old school dots and dashes....

As the new Psvane tubes are made in their own factory, not in the huge Shuguang factory, they could be very different in terms of longevity.

Makes me wonder - any other "great" tubes from Psvane besides the CV181 that I should check out? What's the consensus on the forum? |

Maybe my problem is I listen to much. It takes about a month to get 150 hrs on my office system. The Chinese tubes I have had have barely lasted a year, though I am running a black glass CV181 which has been in for a while. Still good I think but I have been getting some intermittent noise of late which I have been unable to pinpoint. I do agree that for new stock the cv181s are the best sounding 6sn7 I have heard. I have been disappointed with their life span and doubt I will buy more. |
