Title: Old Rangemaster build docs help
Post by: Grazza on October 24, 2021, 08:39:58 AM
Hi all,

I bought a few PCBs possibly in 2010 and have only just recently found them and have started to build them. One of them being a rangemaster. I've been through the archives for the build docs, but the build docs don't match the PCB that I have. Does anybody here know where I can find the original build docs? If I can get it to work I'll post a picture below.
Also while I'm on the topic, the capacitor hole spaces are quite large on this PCB, turns out years ago I bought some suitable axial electrolytics but never got the other caps. Would anyone have any suggestions on what to get?

Go in the Archives zip, the 2011 folder open the pdf there and go to the last page. It shows the layout for this board.

For the three film caps you could use radial if you have long enough leads. The layout shows them as polarized caps but that's only because at the time I had not created the right part in my Eagle library to allow for both axial and radial film caps in the same build.

Here are some axial film that might work:

Great information, thanks again for that. I would have been undecided forever on what to buy. While I'm on a roll, at the same time that I bought the Rangemaster, I also bought a chunk chunk. It has 2010 on the board too, the 2012 documents In the archive don't quite match up to the PCB either. Is there a way I can get a 2010 layout???
