Hi, just wondering if operating the AD1 with a 5K load, 200~220V on the plates and a bias of around -40V at 50mA is a sensible load. Looking at the original datasheets, it looks good, but looking at the EML, it looks a little under. The reason why I want this operating point is that it is very similar to the operating point of a 45 amp, and I want to be able to swap between the two (with the correct heaters of course). Cheers!
