(SIG) Solid state rectifiers are the only REAL rectifiers.

Yes, Actually.
For various reasons.
Such as wasted power, generated heat and reliability problems.

Yeah....
Avoid throwing electronics out as you or someone else might need them for parts or use.
Solid state rectifiers are the only REAL rectifiers.
Resistors for LEDS!

Hi Smeezekitty, Not to take this TOO far OT (How could we BE farther??) , What is the background to your unusual Sig??

Agree with ALL your reasons; About 1964 I built a string of RCA Silicon Diodes with parallel R and C to replace a pair of 8008's in an RCA 1Kw broadcast transmitter.  After too many cold-morning trips to fix circuit-breaker dropout on 8008 arc-back.

... now we return you to you previously scheduled program...
