Interstage and output xfmrs for 38-690
#3

Ron


You are talking active loss resistances, not impedances. Heyboer did not observe it, theybuse thicker wire.As you might remember, from the Diverted's case, he was worrying about the same exact problem, his DC resistances were way lower which was explained by them using thicker wire, but the actual impedance is only determined by turns ratio, and can't really be derived from the DC ohms shown in the schematic. I have the turns ratio 13:1 which given the 8 ohms of the tweeters would present itself to the 6F6G interstage driver as 1,352 ohms of load. 6F6 wants to see 7K of load asa pentode, or 4K as a triode which I think it is the case here. 1.3K is too low.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.

Dan Double conversion is using two IF converters instead of one. This improves the image response. morzh — 07:15 PM
