This is actually the first well-working receiver that I had developed myself, back in the mid 90's. Unfortunately documentation was not my strong side then, so I do not have a schematic. The receiver works very well (in fact better than some of its successors), especially the AGC makes listening to 80m QSOs a real pleasure. Sensitivity is not cutting-edge, but on a full-size short-wave antenna it is by fare sensitive enough.

This is the 3.5 MHz SSB RX from the outside:

and this is how it looks inside:
