Dear all, I am working on this 2465BCT for a while. First I had to recap and fix the A5 board, which I managed to succeed thanks to the help of this forum. I managed to adjust DAC and run CAL08 to try

Hi, I have a Tek 454 in a 453 case that quit working about 30 years ago. I suspect power supply caps. In those days my solution involved getting another scope and I have not checked anything in this m

I am feeling lazy and I am wondering how much current the 547 calibrator can deliver in its 100VDC position. I want to power a Magic Eye, it needs 1mA.

Dear all, my 1S1 gave up. It looks at least one of my sampling diodes has died. Searching through the related messages I noticed most comments are pretty old, so I hope some new ideas might have been

Now that it appears that there is a much smaller offering of 500 series stuff on eBay, where do people get stuff now? There hasn't been a 1S2 listed in years AFAICT. The single 1S1 that's on now has b

Hi All, A common problem with older scopes seems to be the text on push buttons and knobs wearing off. I have an idea for restoring these, but I'm wondering if there's a spec for the font on these? I'
