Hammarlund HQ-129-X
#18

Well, it works ! Today, first I put in all the tubes except the 5U4 and powered it up... the filaments in the 6V6 and the 6SN7 both glowed nicely, and no smoke escaped from anything. Then I connected a speaker to the speaker terminals, and an antenna to the antenna terminal, and jumped the other antenna terminal to the ground terminal. Powered it up again, and BINGO... sound... sound that got louder and fainter with the volume control. I was even able to hear a station weakly on the AM broadcast band on the lowest frequency band, as well as the usual hash from the power lines. I could hear two stations weakly on the next band which has the upper end of the broadcast band, as well as the hash where it is expected. I worked my way up the bands, and they all seemed to be receiving, though faintly. All the controls also seem to be working properly. I was even able to listen to a couple of hams up around 7 MC on single sideband using the BFO, which also seems to be working fine. Next will come alignment.
