Need advices on building a stereo tube amp from PCB

Hi guys,

I will start buiding a stereo tube amp soon, PCB based since I don't want to do point to point wiring since I am not confident about my planning, routing skills 🙄

I am considering a few bare PCB and kits (see below), anyone having an expirence building them ? Or theorical advices by looking at them ?

My dilemma is I know starting with DIY friendly kits from US/Germany should be a safer option, but Chineese kits are more complete and have apealing specs and tubes...



Main objective:
- $600 max for all but the case
- 8w per channel minimum with 8 Ohm load
- Looking for a warm sound

What are less or not important:
- Kind of tubes used
- SE or PP design (with respect of minimum power requirement)- Bass punch
- Absolute specs, I do it has a hobby and a way to continue my amp building explorations


Here are my shopping list:
- S5electronics K-16-LS full kit
Untitled (maybe with the tone tune module)

- German EL34 PP bare PCB

- Chineese EL84 Push-pull class AB full kit or bare PCB

Any help is appreciated 🙂

George Anderson of tubelab.com has popular PP & SE PCB's with a Forum on this site so lots of help.

Pete Millet has sweep tube PP amp PCB's that could be adapted to regular in production tubes if needed/wanted, plus info on his site for other amps/preamps he has built with some PCB's for those also. There are threads on this site on his popular sweep tube PP amps also.
