Down the Rabbit Hole
I look at Ebay from time-to-time, and lately I’ve been having a little too much fun. A Ten Tec Century 21 CW Transceiver (model 570) attracted my attention recently. The “570” was a solid-state radio intended for Novice hams and covered five bands: 80, 40, 20 (and with accessory crystals) 15 and 10 meters.
I mentioned finding two old 20’s-era broadcast receivers in an earlier post. Some months had passed, and restoring the Freshman Masterpiece “5F5” seemed like a fun project and a quick win. The radio was designed to run on two batteries: an “A” or 6-volt battery for the tube filaments and a “B” or 90-volt battery for the plate voltage.
It’s been nearly two years since a pair of classic old shortwave receivers followed me home from California, and they have been staring at me each time I enter the shop ever since. Neither are functional, and both are daunting restoration projects. I wanted to revive some of my old vacuum tube chops and collect some vintage test equipment before diving into these beauties.
A few months ago, I refurbished a Dynaco Stereo 120 audio amplifier for my studio, replacing a Stereo 80 amp that had been in service for years. There wasn’t anything wrong with the 80, but I wanted the increased power and the sound improvements that the 120 upgrades had provided in the studio.
I am listening to a classic solid-state amp from the 70’s. Just a couple of weeks ago, it arrived from an eBay auction in rough and partially-working condition.
In a former life, I worked in professional audio sales and service for a local music store. This was about a million years ago, and the store, Musicmakers Austin, is long gone. I was just recently out of college and the modest pay didn’t matter too much because I was living every musician’s dream: working as a musician — or at least in close proximity to working musicians.
In a previous post, I shared a brief history of the Jupiter lenses, a Soviet-made series that have become popular with mirrorless camera enthusiasts. There are several models, with some — notably the Jupiter 8 — often available very inexpensively on eBay. Intrigued by the possibility of expanding my lens arsenal with an inexpensive but useful lens, I did some shopping, and ended up with one of the 50 mm Jupiter 8’s for about $50, including shipping. Not bad.
