The tubes in the Power 3 are most likly Sovteks.Do you not like the sound of the amp.If the tubes are marked Sonic Frontiers then 95% sure they are branded Sovteks.
KT88 s Sovtek vs Valve Art
I am looking to buy a spare set of tubes for my Sonic Frontier Power 3s. The Sovteks and Valve Arts are the cheapest of the kt88's. Looking for anyone who has used both or either of these types and your impressions.
thanks
