Collins 75S-1In 1958 Collins introduced the Collins "S Line", marking an end to the St. James Gray wrinkle painted transmitters and receivers that amateurs had loved since the end of World War II. This is the Collins 75S-1 receiver, which replaced the beloved 75A-4 in late 1958. Lacking the mechanical filters needed for selectivity, the 75S-1 never really was much of a success. Later improvements in the "S Line" did, however, improve the overall performance of the radios to the level that one would expect with the "Collins" name on it. Overall, this receiver does very well, but I would recommend using a "Q-Multiplier" with it to improve the selectivity. As you can see, this 75S-1 is rack mounted using the standard Collins rack mount.

Hallicrafters HT-20The Hallicrafters HT-20 is one of the most unique transmitters I have ever seen. First of all, there are no amateur band selections on this transmitter. The reason is that it is a general coverage HF transmitter. Because of this, tuning up a HT-20 can be a bit complex, especially in the higher HF frequencies. Appliance operators beware! Another unique thing about it is the 4D32 finial. Other than the Collins 32V series and the Johnson Viking I, it is the only other transmitter that I know of that uses the 4D32 finial. Still another unique thing about the HT-20 is that it is forever linked to the 1954 Dxpedition to Clipperton Island, where two HT-20s, two SX-88s and a HT-18 were donated by Hallicrafters. Difficult to imagine anyone putting one of these in a small boat, through a pounding surf, and dragging it up the beach.

National HRO-60The National Radio Company HRO-60 is an AM & CW receiver which had a production run from 1952 to 1964. It will also do Narrow Band FM with an adaptor. It has one of the widest frequency ranges available, from 50 Khz to 54 Mhz, if you had all the coil sets. This particular one is rather unique because of the S-meter, which looks a lot like some of the earlier S-meters on HRO receivers that National made. I really do like this receiver, however, as with any radio that requires coil sets, lost coils sets can be a real problem. The only coil set that I have that covers an amateur radio band is the "D" coil set, which is for the 75/80 Meter Band.

TV-7D/UAlthough the TV-7 series of tube testers has its share of critics, I think that it is a classic boatanchor tube tester. Its does use a 0-120 quality scale rather than reading true GMhos, which seems to be a major hangup with some people. (There are translation tables out there to overcome this.) And some say that minimum listings in its manual are too low.
However, The TV-7 series are built like tanks and seems to me, to be one of the best designed tube testers ever made. They are great for testing real old tubes prior to WWII. It will test many, but not all, tubes made after WWII. This one is a TV-7D/U model. I have two TV-7D/U and two TV-7B/U tube testers. If you need one repaired or calibrated you should contact Dan Nelson, who did a great job on two of my TV-7s. The tube being tested in the photo is an 812 tube. Take a look at this 0A4G being tested on the TV-7D/U. To learn more about the TV-7 series and other tube testers, be sure to check out Padgett's Hickok Tube Tester Page.
