Hi Leo,
For some reason the photos you think you are adding to your photo album today, are not showing up in the photo album!

Hi Tom,
Thanks for the documents, I added them to my 2215A paperwork and checked my scope for these mod's.
I am in Spain, but based on the SN (204xxx) my 2215A was manufactured in the UK, so it's probably always been in a 220V environment.
I got the impression these mod's were based on the early US build SN's, depending on scope model. (01xxxx - ), and not for the (later?) manufactured UK (2xxxxx) and Dutch (7xxxxx) SN's?
I checked my scope for these mod's, and some were already standard in the schematic of the 2215A, but funny enough there seem to be many iterations around of the PS design, some mod's are to be done only to 2235's, and some only to 2215 but not to 2215A, etc.
What I did do was:
Replaced the Schaffner line filter to be on the safe side;
Replaced the two (already micro cracked) 2n2 RIFA capacitors in the extra line EMI filter build to the back of the scope;
Kept the capacitor C900, it looks as if that one was replaced before;
Kept the power supply mod's as they are now.
Pictures of the removed components are here: /g/TekScopes/album?id=64919&p=pcreated,,,20,1,0,0
Thanks again for the input,
Leo
