I think K7DYY is only new AM transmitter assembled. From what I read it is a worthy product and I believe made since 2004. Produces 375 watt carrier and it is less expensive than tube transmitters of 250 watt and higher carrier power.  It looks like I may buy one.

K7DYY is a good rig. I have owned two of them, the 160-80 and the 80-40. Kinda fussy about SWR and going over 100% negative audio peaks. I could never get either one to produce legal limit output though.
