Hi guys, During lockdown I decided to drift away from solid state gear and bought my first tube amp about 18 months ago. It was the fabulous and insanely cheap Willsenton R8. Then about 4 months ago I purchased a second Willsenton amp called the Willsenton R800i (805 version). I absolutely love the tube sound compared to solid state and ended up buying the R800i to get even more into the hobby, but also get into a SET design without breaking the bank. As my speakers (which I love) are only 90dB efficient, I couldn't buy a 300b at any price because of the low power output. Anyway, the point of starting this thread (and being a new member of this forum) is, as the title indicates, to discuss tube choices, possible modifications (if anyone has attempted such), and impressions of these rather cheap chifi amps. I've also found that I have become totally addicted to tube rolling, so I do have some advice of my own that I am more than happy to share.
