As good as it gets

Don't forget the brain. It also has a 'burn in period' when using new gear.

This is your brain 🧠 This is your brain after burn in 🍳

@geoffkait , that seems like lead substance of high temperature had traveled through brain and fried it. guns no good.

I've heard self-performed lobotomies beat brain burn-in, and work better than hi-temp lead or guns....

Less messy, too...be considerate with your self-abuse.... ;)

If done correctly, you won't have a care in the world....or out of it, either..

after 400 hours everything in the audio chain is fully broken in. the 5-10% won't change your general impression of the amp but it always sounds a little better and less stiff after burn in.
you should swap to nos tubes which sounds much better than the modern chinese/russian crap and tune it to your liking.what tubes types are in there? anything nos 60's made is amazing compared to stock but each brand has their own voicing.
