Ef80's soldier on in reasonable signal areas for ever. They will still be servicable. They required changing in fringe areas where every microvolt of signal was required. The Aurora output is so strong it will bore a hole through any I.F. strip and produce a good result with completely duff valves [or so the valve testers say] I have never replaced EF80's in any television I.F. strip but I was situated at Wimbledon in a very high signal area.
