“These Mullard EL34s replaced the PL stock tubes in my Primaluna EVO 300 integrated amp. The tubes sound great. Only a relatively short burn-in period was required - 2 weeks of casual listening. The PL stock tubes also sound very good - I was looking for a reasonably priced tube to try some tube rolling just for the fun of it. Upscale processed the order really fast. Very satisfied.”

“I bought an octet of these to replace aging original XF2 dual halo Mullards on my 1962 vintage Marantz model 9 monoblocks. I am still breaking-in the tubes with less than 100 hours on them. And yet they sound pretty amazing already! Superb pin-point imaging and that famous tubed Marantz midrange clarity and overall frequency extension comes right through, specially in Triode mode. Overall, I am very happy with my purchase!”

“Great tubes - extraordinary for midrange and vocals. And the service from Upscale- what can I say- always extraordinary!”

“According to my Amp Tech., the tubes were not well matched.”

“The combination of Mullard EL34, 4 Brimar 12AU7 and 2 Radiotechnique 12AU7's can't be beat. I won't be changing anything soon. The Mullard EL34 brings to the table all the things EL34's are known for.”
