Hi It looks like the power bricks are labeled 1.9A. This is at 18V. At 24V max current is probably 1.3A or so. It’s also labeled 25W. That is a good indication the 1.3 might be a little high. It’s a good bet that the -15V output has nearly zero load, so the “real” max should be below 1A at 24V per box or 2A for a pair of them. Once the OCXO cuts back, the + 15 should not be loaded very heavily. Yes, that’s very much what a TBolt power supply drain looks like.
