I will forever be a tube sound lover. I’m an old retired guy here to mod and update my R8. I am not a trained tech of anything. But show me a recipe, photos, videos and I’ll get the job done. Works for me. I have everything but the resistors and capacitors before I ask my neighbor to move the 65 pound beast to my work table. Oh, recently V2 red plated. Makes me feel like some kind of veteran. My new T-shirt, “I Got Redplated”. Wish me good luck!🍀
