HA HA HA. Why don't they use better resistors, capacitors, chokes or
transformers, chassis metal thickness, feet, etc. Cost to price ratio?
I think those would make bigger improvements than some fuses IMO. Why
not just use a copper bar?
Any designer worth it's salt don't just assembled a combination of most expensive parts but a combination that meets a goal.
I understand every time a DIY replace a part, WOW!!! Unbelievable improvement, more organic, resolving ...
