Hallicrafters S-86 receiver

This is my 'new' receiver. It's a Hallicrafters S-86, which is the AC/DC version of the S-85. You can see me measuring if there's voltage on the metal case. It still has some of the original caps, i'll be replacing them sooner or later. Maybe i'll add a safety transformer too. After replacing the electrolytics in the power supply, it works just fine. I used slightly smaller values than original, because i didn't have any larger ones. Because of that, it hums a bit. I'll add some more capacitance when i'm replacing the wax caps still in place. It misses quite a few knobs... This receiver is very sensitive, the audio is quite good (much better than in the video- the photo camera doesn't have a good built in mike) and the selectivity is good enough. It doesn't have any fancy filters apart from a simple tone adjustment switch (the thing i turn with the green pliers) It isn't very stable directly after switching on, and don't make it vibrate... it'll jump quite a few 100's of hz as you can hear, when i tap it with my finger.) i absolutely love it! it's got way more charm than my Yaesu FRG-7, and SSB reception is much better intelligable. The 'pitch control' thingie lets you adjust the pitch of CW signals, or choose between USB and LSB signals. I still have to get used to tuning in with this receiver. Local time: 16.00. Location: Zaandam, The Netherlands. Antenna is 15m longwire.
