Re: Solartron CD 1400 Oscilloscope Refurbishment
Replaced the four 0.01uF/10,000pF 350 volt ceramic capacitors C314 - C317 (with 0.01uF 630 volt poly caps) on Board 3, these are used around the Focus & Brilliance pots. They were not really bad but all 4 measured around 25% low on their capacitance and were slimly and a couple of them were starting to crumble.
For a change the new replacements were larger (slightly) than the original old ones.
Thought wise to replace them while the board was out and had plenty of spares.
Tried to measure the ten 8uF 450 volt electrolytics C301 - C311 on Board 3 in-situ, but due to other connected components could not get sensible readings, so am removing one at a time and measuring. 5 done so far with good capacitance and ESR readings.
