I am preparing to restore a 2510. I have not been able to find a build manual, user manual, service manual, parts list, or schematic (if anyone has any of them and is willing to share, please PM me). I am creating a parts list by going through the unit and seeing what is in there now. I am interested in your input, comments, and advice as I create my parts list.
I plan to replace all of the electrolytic capacitors, and all of the carbon composite resistors. I do not plan to replace the ceramic disk capacitors. If there are parts you absolutely would or would not replace, please let me know.
I am having trouble identifying some of the other components. I have attached photos. The numbers below refer to the numbers in the photos.
1 - Is this a small PIO cap? If so, should I replace it? I normally would on a rig this old. I would probably use a polypropolene film cap, like an Illinois yellow drop. Thoughts?
2 - Is this a wirewound resistor? If so, should I replace it? I would normally not replace wirewound resistors unless there was an issue. There are a number of wirewound resistors of various values used throughout the unit.
3 - This looks like another PIO cap. Same questions as for 1 above.
4 - These look like tantalum caps. If so, I would normally replace them with electrolytics. Not sure how to determine the value. All I see printed on them is "22" which might refer to 22uF.
5 - Another PIO cap?
6 - Not sure what this is.
7 - These are 1N541 germanium diodes. Replace them? That is what I would normally to do.
8 - This looks like an old Black Beauty style capacitor. I would typically replace it with an Illinois yellow drop, or something like that.
9 - These gold things look like larger PIO caps. (I know the photo is not the greatest.) Not sure what to do with them, i.e., keep or replace. I feel like I should leave them, unless there is a specific issue (maybe because they are so nice and shiny).
10 - I expect these are film resistors, maybe carbon film. There are many of them throughout the unit. I would not normally replace film resistors unless there was a specific problem.
Thank you for your input. When I have the parts list finalized, I will post it.
