PS: I think the photo of the underside of the chassis isn't a SRS153 but a SRS152. Please ignore. The PDF and schematic are correct.
I see no great problem in replacing the CV2235 (=EY84) rectifiers with suitably rated silicon. A pair of 1000V parts such as 1N5408 in series, with 10M equalising resistors across each diode will be OK. Suggest 47R 10W resistors in series with each pair of diodes. The choke input filter ensures there won't be any high repetitive surge currents.
I fitted a switch in series with the HT+ output. This means I can let the PSU warm up properly before switching on the load.
