<p class="MsoNormal">If you get truly desperate for working HV supplies, I have a CAEN V6533 VME HV module with 3 channels each of +HV and -HV at UConn. However, it is only rated up to 4 kV/3 mA, so very marginal in terms of suitability for GEMs, which need
to operate right at 4 kV and sometimes slightly above. On the other hand, if there happen to be a few GEMs with an optimal operating HV below 4 kV…
