Re: SX-110 2nd IF Circuit Design

Thanks, Mike!? In contrast, National often used all 6SG7¡¯s in their IF design (such as in my HRO-60).? The difference is an interesting point. ? 73 ¨C Steve, KW4H ? Hello Steve!
Excellent question!
The 6SG7 has higher gain than the 6SK7.
The 6SK7 can handle stronger signals.
And the 6SK7 provides better AGC control since it¡¯s a remote cutoff tube.? The 6SG7 is semi-remote cutoff. ? I hope this helps!

Subject: [HallicraftersRadios] SX-110 2nd IF Circuit Design? All, ? A curiosity ¨C I¡¯m restoring a SX-110 at the moment and see that a 6SK7 was used for the 2nd IF, while a 6SG7 is used for the 1st IF.? I¡¯m trying to understand why that is ¨C why not use two 6SG7¡¯s?? What was magical about the 6SK7? ? 73 ¨C Steve, KW4H ?
