You take things to perfection, ultimate solutions, that’s great, for you and others.
I go so far, then stop, not enjoying pursuing perfection any more.
Three fundamentals I simply do not understand people not having.
1. TT, Have a Dust Cover. Expensive/Precise Equipment exposed to airborne .... no way.
2. Tubes: Have a Tube Tester (basic, not advanced unless desired). Uninformed, blindly searching/thinking perhaps a bad tube .... no way. Members and yourself wildly guessing, jumping around like a cat on a hot tin roof, no no no.
******Driving along, trash, driveway sale, thrift store: see a discarded thingy with tubes, yank em, the tubes are very likely good, you can test them when you get home or later if you need one. Using a used tube gets the music playing while you look for new ones at a good price.**** Don’t forget: many tubes last 10,000 hours, so a used one that tests good ....
i.e. I just tested all my tubes friday (I test them 2-3 times a year). matched sets still matched? anything weak?
my mx110z tube tuner/preamp: found a 6au6 with a short. Had none in my collection of new/used tubes. Checked/yanked good tested used one out of a Fisher 500c I will be selling.
mx110z has 17 tubes, I don’t know what it was doing, I didn’t hear anything wrong, or different after I replaced it, but it does something. I very rarely use the Tuner, I suspect it is in the tuner section, who knows? My Fisher 500C uses 1; this uses 3, They are not expensive (now) I am going to buy 4 now for the future. And: test them when I receive them! Test any tube you buy, especially ’matched’ sets.
3. SACD/CD/DVD Player: Have a Lens Cleaner, try it 1st! I have ’fixed’ many of my and friend’s players over the years. Same thing in the VCR/Cassette era, have a head cleaner., it’s the 1st thing to check.

there’s others, but these always leap out of my brain when members have related problems and lack/skip the fundamentals.
