dynaco st 70 what tubes to replace first


Ive just bought a rebuilt st 70 and am very happy with imaging and sound quality Ive checked the tubes that are with it and they are run of the mill. WANT TO UPGRADE !!

Suggestions please on what order to replace first and if you can; recomendations, Im looking for a creamy thick sound.

Im an old guy and this is my first tube amp and limited knowledge but a fast learner and very excited to go back to non-ordinary reality via sound.

Have you ever tried the gold Lion KT-77's? I was thinking about trying quad of them when funds allow.
I also own a Will Vincent rebuilt ST-70 wired in triode. I ended up changing all the tubes. RCA 7199's made a positive difference. I tried SED "winged C" el34's and a quad of Siemens el34's. I much prefered the Siemens, winged c's being too rolled of at the top for my taste.

But getting a Mullard fat base gz34 made it sound like a whole new amp. A much better amp. I actually couldn't belive what a positive impact it had on the sound. So if I had a limited budget for tubes, I'd spend my money on a Mullard gz34 first.
