I just got this vintage Heathkit IO-10 oscilloscope from ebay. Just tried powering it up and it seems to be working fine. But I noticed that the OC2 tube seems to glow very bright orange and the OA2 glows purple and works fine. Occasionally there is flickering in the OA2 tube as shown in the video. Is this normal for both the tubes?
I've added a video to help understand better.
Also I've a question regarding replacing the two can electrolytic capacitors. Can the first cap 150V-100MFD(3 caps in one)be replaced with a 250V- 100MFD and the second one (400V-350V-250V-150V - 40-40-30-40MFD(4caps in one) with 450v-68MFD?
