If the emission works but not the pressure, U7 is likely damaged.<\/p>\n\n\n\n<p>On the really old 11-065s, U6 was a TIL109 opto.&nbsp; When that part became obsolete about 20 years ago, it was replaced with a SPX314 opto.&nbsp; Most of the 11-065s in the field have been updated to the SPX314 (a modification is required). &nbsp;&nbsp;If you have a really old 11-065 with the TIL109 opto-couplers, RBD still has a few of those in stock.<\/p>\n\n\n\n<p>Recently, the SPX314 has become obsolete and is hard to find.\u00a0 It can be replaced with a OPI1264 opto-coupler which is also has 15kV peak of isolation, so even if the HV1 board goes up to 6.4kV this opto-coupler will not get damaged.  The OPI1264 will not only repair the problem, it will ensure that this particular problem does not happen again.<\/p>\n\n\n\n<p>There is no modification required to switch from a SPX314 to an OPI1264, but the pin outs are slightly different and are shown in the pictures below.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img data-attachment-id=\"2621\"
