Don,

?

I just checked, and yes – there’s a third IF tube for the SX-42 – the 7H7.? I overlooked that.? FYI, my Osterman book is the fourth edition.

?

73 – Steve, KW4H

?

?

Scott, and ?Steve and the gang:

I think Steve clarified a mistake re the sx-110 , but he listed IF tubes for others ?and never said anything about my comment on the sx-42 .

he listed?? “SX-42 (1947-50) 6SK7, 6SG7”?

?my? ?1996 Dachis ?book and my ?Osterman? book says ?6SK7,? 6SC7, 7H7

I also said “Wonder if we have the same printing…”

?

Now I wonder if ? my? ?1996 Dachis ?book and my ?Osterman[ second edition]? books ?are wrong ??about the 42

?

For the 62 you mentioned ?,Osterman ?lists the same IF tubes as it lists for the 42, [6SK7,? 6SC7, 7H7] and also says the A version seems to be the same except for the speaker impedance,, BUT Dachis says? 6SK7?6SG7?6SG7?

I guess I must be off-track, and/or cant read these details so maybe somebody else can check these books?
