Hmm ...

I wonder if this is the same receiver I built a ways back?

Wow...when "Big Nick" takes notice of your projects, that must mean you're doing something right.

You're describing the SuperX Superhet Mk][, which uses a regenerative first detector. I have a 1959 ARRL manual and it describes the original. However, I want to make several changes...

- traditional intermediate frequency transformers at 1700 KHz, which will be hand-constructed by myself.
- a 6EH7 intermediate frequency amplifier, controlled by AGC.
- an audio amplifier capable of driving a speaker at ~500 mW or so. As much as I'd like to construct a set of moving-iron headphones, that's probably not going to happen. I'm thinking of using a 12AU7 as the audio stages.

Right now, I'm relishing in the completion of my power supply and I'm slowly working on a single tube regen using a 6BL8. It's not going to be the end-all-be-all receiver for a high-performance station, but it will be using tubes and I'll have fun with it until I get there.
