What are they ... I am building a amp and just using 1/2 watt carbon composition

Actually, it seems as if NEW caps are just as bad
if not worse.
Chinese capacitor disease seems to be a pandemic.
One of the few remaining local parts retailers just switched resistor brands
after many years. The new ones are visibly crap
(but apparently they 'sound cleaner' to the audioph**les who are some
significant portion of his market). Just one retailer, or is this is the next step towards
death of 'conventional'
home-brew electronics and repairs? With the market for wire-lead components
having been so reduced by SMD, what market remains is filled by low-quality
manufacturers.
I am looking at the new resistors ... all film resistors to blow at .1% greater
wattage than specified
@ 70C. I planned to use ordinary 5 watt power resistors, but they don't handle
momentary overload
at all nowdays, so I had buy 'audio' resistors at 10x the cost. 50 cents vs 5
dollars.
