New Dremel cordless, Now tube radios.

[John Ferrell]

It was a 12AU7. The 12AU6 was an IF/RF amplifier used mainly in automobile receivers. This from the same memory that cannt rember the sequence...!

  Ron,

  I had an electronics lab kit from Allied Electronics when I was a kid. Had a 12AU6 (or 12AU7?) twin triode tube. I was elated when I hooked up a hybrid AM radio from the schematics -- and it worked!!!

  Luckily, transistors had been invented by the time I got into RC. My first radio was a Kraft 5ch Sport Series. Had the big KPS-11 servos with the linear rack outputs. First plane was a Goldberg Skylane 62 with OS .35. Lasted 6 flights (midair). I had saved up money working during the summer to pay for that. I was 15. 

  When I learned amplifiers in school, we covered tubes first, then transistors.

    I had a receiver, which had an RK61, but it never worked. What I flew 
    was an ECE receiver, which had a 3D6 tube, as I remember. I still have 
    it. For you young guys: This all happened just after dirt was 
    invented.
