[Hi, at 20 hours I checked the Bias and every thing was ok all tubes 065 mV. After 45 hours I measured again.
The V2 had 067 mV and V4 was at 064. All other tubes were at 064-065. I adjusted the V2 back to 064-065 and I measured then on V4 only 059 mV
After 2 hours I measured again 066 on V2 and 062 on V4.
On first use the VS115 matched with LS26 was very close to REF110. Then after 10 hours it exhibited a darkish character, without the tubey warmth, dry and mechanical sound. After roughly 55 hours things began to change and soundstage opened up, detailed and smooth.But i think i have to wait for ca. 150 hours to break in for full improvement. The sound of LS26 also evolved during the break-in period and i heard no further changes after 160 hours/]
