Very nice integrated amp, made in Germany. What speakers are you running? What output tubes have you gone to, KT88 or maybe TS KT170 used in the Ti 100 MKII?

The QS V4s before being discontinued had a cycle refresh with upgraded transformers that were suitable for a wide range of output tubes, from the el34 to the kt150. So yes they had the correct voltage to handle and maximize the kt150 tube. Before the change he had like 300 screen v. Not enough to push the kt150s which do much better around 600 v.
Very puzzling?

The Quicksilver V4s always had 600vdc on the plates - garymuffley 11:11:36 01/19/24 (1)
You are incorrect in assuming the plate voltage on the V4s changed from 300vdc to 600vdc. The screen grids are at 300 vdc.

  Yes, correction. Screen voltage.
  Are the newest version still 300 screen v? Now disconnected.
