Hi Nguyen,
i decided to build the old dac end (cheap version).
i could not get all the needed (four pcs) pcbs so i am still looking for two pcbs for it.
1. Dac pcb (ad1865)
2. Power supply for iv stage
The other two pcbs (power supply for ad1865 dac, iv stage with two 5687 tube) i already have.
Do you may have these two pcbs which i am looking for?
thks
glaci

Do you think it would be a good idea to elevate the filament to 100volt?
