Down the Rabbit Hole
I was recently asked about the power switch on the Ten Tec Triton IV transceiver. Was it capable of switching the 12-volt line used to power the radio? The short answer is no. Co-located on the volume control, it was intended to switch an external power supply like the Model 252 or 262. Switching the 15 or so amps of 12-volt power needed for the 100 watt transmitter would destroy the switch.
By now, I’ve written about quite a few classic Ten Tec radios. There are those who would argue that the Argonaut, first introduced in 1972, started it all though. It was the first recognizably Ten Tec product and would set the style for decades to come. It was also the first popular QRP transceiver that included both CW and SSB modes.
I finished circuit repairs on a Ten Tec Triton IV transceiver and now it was time to address the grubby cosmetics of the radio. The radio had obviously been used as a mobile. Markings had been added to the front panel in Sharpie, and there was a yellowish film on the panel.
In the last post, I described a used Ten Tec Triton IV and addressed the most immediate issues. I also mentioned making a cosmetic restoration, but after using it in the shack for an evening, it was apparent there were other problems. The “Offset Tuning” (OT) LED didn’t work, and more seriously, the transceiver didn’t always mute in transmit. Strange sounds issued from the speaker at times.
eBay has provided a lot of entertainment (and used equipment!) over the last few months, and after the purchase and restoration of a Ten Tec Century 21, I started looking for a Triton IV. This was the first radio I purchased new in 1978. I really enjoyed it and wanted to own one again. It didn’t take long. I ended up having two in the shop at almost the same time — one for my shack, and one for a fellow ham.
