what is the best cassette tape maker in your experience?
No I never bought cheap tapes as I plan to keep them and didn't want to lose material. 
L-Pads. Speakers Awful Without Them, New Ones Ordered
Fixed resistors always sound better for trimming driver output. With older speaker designs L-pads were needed to make the speakers more versatile. Fixed resistors on switches is a great replacement to L-pads. Tone controls definitely don't cut it,...

For me, TDK beat Maxell every time. I did like the TDK Audua when budget was tight. 
Rare Vintage Find : "Norman Laboratories electronic crossover - amplifier System 12"
Post deleted, inaccurate. Looks like each box contains 2 amps which could drive one 2-way speaker in a bi-amped, not bi-wire configuration. Sorry, I have no idea how to hook them up. I don't understand the terminal labels on the rear panel. 
Manley Amp is humming - troubleshoot :(
Are you good with a soldering iron? Look for any capacitors that are bulging or leaking. A thorough visual examination of all components and solder joints before doing anything. 
Stacking Components
Been discussed before, https://forum.audiogon.com/discussions/stacking-gear-no-more-rack-space-does-it-affect-sound-quality*All electronics fail mechanically first. Either due to heat or vibration, good luck.

Oh, you switched channels not amplifiers. Output transformer is a possibility, but FAR less likely than a cap. 
Krell DUO 300 XD vs Krell Solo 575 XD
Question, what speakers are you using, ML model? Yes, I'm familiar with both Krells you mentioned. Very good amps, but only 40v/µs rise time. They don't have the "sparkle" of some other amps in their price range. I don't like the fans when they co... 
Reasonably sensitive speakers for tube amps, max $2k/pair, new or used

Why have capacitors improved so much over the years?
Some good answers. Many new cap technologies driven by military applications primarily. New materials and improved manufacturing processes. Electrolytics have gotten smaller, but basically unchanged, still used because they are cheap. Capacity/cost. 
FEX EX Damaged New Legacy's
I've received several items that were shipped "signature required". They were just left at the door, one damaged the other okay. Maybe it's a COVID thing?

OP, I thought you said you switched amps? tvad, think you nailed it. 
Manley Amp is humming - troubleshoot :(
I assume it still hums with all inputs (sources) disconnected? If so, then I'd suspect a capacitor in the preamp and will need service. Unless you feel comfortable, I would have a professional tech look at it. 
Onkyo P-3000R gain adjustment?
I don't own one, but many preamps have adjustable gain through their onscreen displays. This is used to normalize the various inputs so one is not significantly louder than the others when switching between inputs. I'd spend sometime checking all ...

Sad to hear this, RIP. They could rock the house!
