@doyle3433 can you look at your order build sheet to confirm which coupling caps they installed in your HS model? Also, I'm not familiar with what stock tubes they come with now days, is it still Electro Harmonix or something else now?
I'm helping or tracking along with a friend with his SLI 80, and he's rolled several output tubes and at least 4 different input tubes on his own, and seemingly not "there" yet. Now he's replaced all the KT88s, trying different EL34s, wanting that type of midrange sound for his 3-way Klipsch Hersey IVs, which are NOT like his former Hersey IIIs. He's acting super itchy now wanting to swap out the stock (lower version) Mundorf caps his came with. I'm talking about someone who swaps coupling caps more frequently than most people change tubes - that kind of over obsession. We'll see. We talked and thought it was best to let the amp truly burn in another 30 days before jumping to conclusions, screwing with the caps yet, its too early imo. For now, maybe its worth doing some research to determine what other type amp/tubes work well with you Volti Razz (other than Gary Dews 300B amp). Its helpful to decide if you want to keep KT88s or attempt EL34 instead, and only you can answer what's missing from the sound after its burned in at least 30-45 days, would be my suggestion. You might like it stock after its all settled in, yet I don't recall how much time you have on this amp/tubes/caps overall. .
