Assume each Footscray tube life is 6500* hours (after 100 hour cumulative burn-in). With 5 hours per day, including warm-up, for every day that would be 1300 days or 3.6 years. A day off (!!) here and there stretches this out. Swapping between CV4033 and CV455 definitely stretches this out .
*Probably conservative…the tubes are in headphone amplifiers not in power amplifiers for loudspeakers; and in the MJ-II, the tubes are pre-amplification; the SS output buffer does the heavy lifting. (Tubes = brains, SS = brawn).

I think that I can get these made up. I will put in for one size: large. Will toy around with print colour / background colour…and be back. Again, for your viewing pleasure (ideally while listening):
