Hello, is there a simple tube output stage out there i could copy? im probably gonna use jlsounds ak4493 dac, it has differential outputs, im also not sure what voltage requirments tube have, fairly new stuff to me
Try to read about tube circuits first, after that look for, and decide on a single ended low power circuit.
For any meaningful output power the voltages are in the 200-300V range
Before building anything read up on how to work safely, without electrocuting yourself or anybody else.
Google is your friend 🙂
Maybe you can find a "Radio Bastelbuch" from K.H. Schubert, or something equivalent , that should help to get started

hmm i think i might test a tube buffer at some point, i probably stay with opamps for the dac
safety isnt the big issue here, i know my way around 230V but it certainly complicates things

How much power do you need? You can get maybe 5 watts from a Class A amp, which could be one output tube. For more than that you'd want push-pull (Class AB). A power amp will need a few hundred volts DC. The biggest problem will be finding the appropriate output transformer. Here's a starting point:

a amp would be a completely different beast, i was talking about a tube buffer between dac and amp 🙂 but i would probably need atleast 50W for some headroom
after my dac build is done i might DIY some speakers, then i would also need a dedicated amp, i currently have active speakers (studio monitors)
