Many thanks guys....and Half Life hit the jackpot..the datasheet actually states it's a drop-in replacement for the 2SK146...with a better noise figure....the Amber may live again...!!...I was nearly giving up...actually started looking for a used QA403... I do need to come clean and admit I don't own any Carver gear...although have repaired some in my time. ...does that count...?

Currently trying to repair an Amber 3501 test set...circa 1988. Checking out whether it might be possible to improve the input section with modern semiconductors...particularly since the 2SK146 Dual JFETs are unobtainium....Thinking some members might give me some pointers.
