I have now obtained, courtesy of Diabolical Artificier, a B9A valveholder, and am in the process of wiring it into circuit, replacing out of tolerance resistors as I do so, five of them being mounted directly on the valveholder. All being well the 2022 will be up and running again once this is done. At the moment the original CC rectifier is still in use.
