[Sten]

2x12AX7 and 1x12AU7

Can someone rec any tubes for that configuration? Its for a Music Angel pre-amp which I originally posted in this topic :

What did you buy today? (Part 1)

[IMG_20201221_155916] Now that’s a big pre-amp Its a refurbished Chinese higher end product from a company that does not exist anymore (at least i did not find anything). It cost 250 euros and is built like a tank. Now will have to find some better tubes, currently the tubes say “China xxx” on them with red letters It uses 2x12AX7 and 1x12AU7 Here is the original add on a local website, also a picture of the internals there if you are curious https://www.okidoki.ee/item/musi…
