Glad you were able to step back and take another look Vince.
0.150" pitch for the header ? That used to be a common one.
Sadly for me it looks like is not so common anymore ?!
I just looked at my two main/local suppliers here, TME and Farnell... none of them have anything suitable ! They do have a FEW 0.15" / 3.81mm pitch board to board connectors, but they are very bulky and weird looking, nothing to do with our thin low profile usual connectors.
Had a look at mouser in the US, just out of curiosity (since I can't buy from them anyway, other than importing), and same as Farnell, all they have is this funky connector model :
https://fr.farnell.com/hirose-hrs/fx30b-4p-3-81ds/connector-header-4pos-1row-3-81mm/dp/2451006I can't quite believe I am defeated by a bloody connector ?!
I mean if I solder the board back to the main board, without connector, I won't be able to remove it at will to trouble shoot itr and work on it... because once it soldered to the scope, access is horrible and I won't be able to probe anything, never mind replace any component. The board and PCB traces almost survived being separated ONCE... they won't survive it twice or more, that's for sure. Not to mention the work/hassle it is to remove it, brrr... 27 pins in a single row, double sided, not fun...
So... that's bad news. Now all I can do is solder it back and cross fingers that it still works and that the "dim" trace problem when the delayed time base is enabled, is not located on that little board...
Decidedly, this 2215 is driving me nuts each step of the way ! :-/
I can't believe I am in trouble just because of a bloody connector ! A silly little, humble connector !
Come to think of it, I had the exact same problem when I repaired my 2232 last summer, if you remember ?! No of course you don't remember, just kidding !
I had a bad connector, a wire to board connector, that connects the main board to the big digital board. Was impossible to find a replacement ! I posted on the forum with this specific request, and nobody could find one either ! Luckily I could get a way with it , by soldering the wires of the cable, directly to the digital board. The cable had a (removable) connector at te other end, on the main board, so the digital board could still be unplugged, phew.
So, I guess that's now x2 22XX Tek scopes endangered by obsolete large pitch connectors ?! Starting to make me feel uneasy about these scopes... being at t eh mercy of such a futile little component, how frustrating !
