Totally Agree Andy.
The equipment was designed for a valve rectifier and really should always have one.
There are big disadvantages with silicon, obviously the surge then adding limiting resistors to tame the running HT which defeats the purpose of silicon as the resistors have to dissipate waste through heat, the big issue for me is the peak voltages that shorten the life of smoothers and of course breakdown on paxolin tag strips and even valve bases
A good indirectly heated rectifier removes all of the aforementioned issues.
