[AMRadio] Viking II Audio Mod Question: Thanks

[Larry Szendrei]

Hi Scott, 

I don't know if you read my reply to your inquiry on the AMwindow
bulletin board, but I had suspected you had the Ranger speech amp in
your Viking II. Keep the mod (or improve upon it!), it's much better
that the original 2x6AU6 circuit. I know, I've got 2 Viking I's (same
audio section). Neither of them still have the original circuit in them,
although they did when I originally acquired them. There's a good reason
why!
