I have been reading about DHT preamps for a while.
After finally making a decision to give one a try, I started digging in the audio closet and simming a power supply using PSUD.
I have almost everything execpt a few resistors and the tranformers for the Coleman regs.
I have decided to build with the Russian 2p29l, mostly because of cost, but also because of reports they are least microphonic ot the popular tubes vintage or Russian.
I have a layout for.the power supply chassis.
LCLCLCRC filter, Coleman filament regs.
I have 4 tubes ordered for ebay seller,, they come encased in aluminum, I have freed one of them.
I will try both canned and de canned just for fun.
I hope to make progress on this in next few weeks, as my 2A3 amps have stalled for a while.... and as we know an idle mind is the devil's work shop.
