Sorry for hijacking the thread.  |
Pre-assembled so that the HV could not be misadjusted (required for UL listing, I'm sure), the builder was prevented from making rough solder connections that might cause corona, etc. The IF also was a potted pre-aligned assembly that used a complex LC filter, so the builder didn't have the impossible job of aligning without test gear.
