I added a choke input regulated power supply of my own design

Which should produce around 410v with 130mA of ripple for a 180mA draw (ie quiet enough).

I had the transformers custom wound for the application by a British firm and badly knocked together the chassis.

This is roughly how it looks now although everything other than the HT wiring is now complete.


I'll get on with finishing it at some stage and it's twin for Stereo operation.
That is badass - nicely done!

KT88's can pack a wallop for sure.
