The G76 is about the only vintage radio I am interested in owning. I had a few in the past and should have kept the clean one I had. I just got another one off ebay for a great price. I have worked guys using one that sounded great, and they reported even more power out then stock. Does anyone have any good mods for the audio? Someone had added neg cycle loading to the modulator, and it also sounded quite high fi. 6DQ5 modulated by a pair of 6DQ6's, audio on the screens, grids grounded, zero bias triode connection... The little audio output transformer has a winding for driving the 6DQ6 screens. A 6CM6 does the audio output and driver job. The G76 does 80 to 6 meters, the touchy vfo does 80 to 10 meters, the ones I had were fairly stable but very touchy in tuning. The RX is nice, a 262 KHz IF gives nice selectivity, and you can adjust the shape by changing the resistors across the IF can coils, and the cap from primary to secondary. Removing or increasing the resistors increases the gain and narrows the IF response. The 5 pf cap from primary to secondary shapes the response as well. An SDR on the IF last section would allow one to SEE the shape of the IF response (and width) if you set the sdr to 262 KHz. Since its plate modulated, the little G76 can do 60 to 80 watts carrier output, depending on how hard you want to push it. Lots of grid drive and 700 volts on the plates gives good results, and the radio seemed to take abuse very well. I think it is a very attractive radio, and its super easy to work on, slide the case off and its all there.
