A fun receiver  Time owned: more than 12 months
I bought a S-76 from a ham in Iowa a few years ago. I had always lusted over one, mainly because of the large S-meter (I love meters). For its age, I find it to be a pretty stable receiver and the selectivity is great for the design. The audio quality is quite good for a "non-hi-fi" single ended audio stage.

I improved the receiver by rewiring the detector to one similar to what is used in the SX-100 and made appropriate changes so the meter and AGC also work in the CW mode with the RF gain wide open like more modern receivers. (If anyone wants the changes, contact me).

BIG S-Meter!!  Time owned: more than 12 months
The S-76 was historic in that it was Hallicrafters' first double conversion receiver. A very important achievement for its day because it eliminated so much garbage associated with single conversion receivers. The S-76 was the first in a long line of evolving receivers, all bearing many electrical similarities to the old 76. The SX-96 and SX-100 are essentially "evolved" S-76's with larger bandspread dials (but smaller S-meters), 100 kc crystal calibrators, etc., but basically they are all just fancied-up old S-76's. A hybrid mix of miniature and octal tubes, the S-76 covered broadcast band + 160-10 meters. Calibrated bandspread was provided for 80, 40, 20, 15 and 10 meters. It's not particularly finely calibrated and could never serve as a "frequency meter," but it gets the job done. Tuning is very smooth, making it easy to tune in CW or SSB. Sensitivity is as good as any receivers of the day. Stability was remarkable then and now, but as with all old tube receivers, it does benefit from an hour to warm up if you're going to copy SSB. The low frequency 2nd IF gave outstanding skirt selectivity without the "ringing" of crystal filters. The S-76 cleans up nicely, and really benefits from fresh mylar capacitors and a fresh alignment. Electrolytics will be dried out by now, of course, and will need to be replaced. Aesthetically, the S-76 competes nicely for title "most beautiful receiver ever designed" because of the extra-large S-meter. This meter grabs your attention and holds it, even though it only works on AM, not CW or SSB. It gives the receiver a nice "professional" appearance unlike almost any other receiver ever made. Overall a nice performer - no, make that a GREAT performer. After restoration, it'll be good to go for another half century. I wouldn't part with my S-76 for all the tea in China.

Great RCVR with a HUGE S-meter.  Time owned: more than 12 months
My first receiver as an amateur operator (1954)was the S-76. It wasn't as stable as a 75A3, and it wasn't as versatile as an SX-42, but it WAS a sweet receiver which performed well on A.M. and C.W. It has good sensitivity, and excellent selectivity. The addition of a tunable pre-amp didn't make it "20 dB better". I used to refer to it as a tunable R.F. microvolt meter with a speaker attached. The S-meter was something to marvel over. For a beginner like myself, it was a dream rig....then, along came the HQ-180 and I could easily tune in the Donald Ducks, Hi-Hi.
