About 2 weeks ago I traveled through the country in order to pick up – as one may guess – another Tektronix oscilloscope! Who would have thought? This unit was very special: a Tek 7904A with many high-speed plugins such as 7A19, 7A24, 7B92A… just to name a few.
The seller was very kind and showed me more stuff laying around in the basement. There were some vintage instruments on a dusty shelf but the Tektronix R556 dual-beam oscilloscopes really caught my eye. We discussed about the future of some of the test equipment and we agreed to “dispose” it the “proper” way: load it in my car and drive it to a place where it will be treated with love and respect… my apartment! 😉
I’m a TEA with somewhat heavy GAS, that’s for sure. But I have never possessed anything like a Tektronix 556 dual beam oscilloscope. Two of them. It was very difficult to carry them around because of its mass of approx. 30 kg per unit.
Nevertheless, the units made it to my home without problem. Initial visual inspection showed a somewhat pristine condition! Besides dust, all vacuum tubes were present and all knobs/plugins/parts were without any visible damage.
I was lucky to get two fitting bezels from Matt@Wellenkino and a proper AC power cord from eBay (type NEMA 5-15R). I’ll have to wait with power-up until order has been restored in my apartment. 😉
