Eimac 4X250B – beautiful little tubes . . .
The restoration of my KWS-1 will begin this weekend. I expect it to be a good 2 weeks at least before it is done. While I am waiting – I will restore the power supply – which is the easy part.
I might invest in a tube tester – there are some nice one’s under $100 – and plenty on the market. One thing that is really nice about these Collins rigs is that they have enough space inside to do work. Making sure the tubes are good and replacing the capacitors is 95% of the work – and so it is something I can handle. The 75A-4 and KWS-1 – require more work – above my experience, and the alignment requires test equipment and experience beyond my pay grade.
