Schematic that you provided us is compatible with low signal I-out DAC as TDA1541, AD1865, etc (just different R I/V needed). It is simply too high gain for V out type DACs with 1 - 2V RMS ready.

For V-out DAC with opamp V output ready I would use cathode or anode follower, based on 6N6P or something like that valve. Schematic and calculation you can find in lampizator site, just google "lampizator 6N6P".
If supply voltage or tube type is not ok for you, let me know, I can help with calculations.

However take care - Vout as usual is worse approach, than I -out (except few TDA, AD and Wolfson DAC). And you will have one more capacitor in chain.
So the sound can be not so natural, IMHO.

yes...caps before and after the tube...I think it depends on the quality too...

maybe a good shunt psu will improve it too...

30 USD for 2 x simpler simplistic + 2 x filament PSU regulator, totally 125mmx 250mm PCB, is not so expensive, IMHO.

Same size, but not gold plated bare regular PCB in ebay shops costs 15 - 22 USD even without delivery cost.

Here we have delivery and Paypal fee already included.
And this is not regular production of bare PCB...

Regards

30$ is for ONE pcb! Be careful!
