My kind of what the...

For all the guys who say their eyes glaze over reading the long theory threads, I empathize: http://www.tdpri.com/forum/shock-brothers-diy-amps/299666-converting-1-2-wave-full-wave-rectification.html .

I recognize, but don't understand most of the terms. I recognize and can follow most of the schematic, but do not understand the significance of the values.

What is important for me, is to hear how guys with this kind of knowledge speak to each other. On those occasions that I try to learn electronics, it really helps to see ways that it is applied.

Now, the problem that I have in learning something technical, whether electronics or math, is that the discussion moves to fast for me. If I hit a minor bump in understanding, I'm screwed from that point on. For guys wanting to learn more about theory, it could be the same for you. For starters, I think you need to have memorized at least the major scales, triads, and seventh chords. That way, you can understand the examples that are used in a theory thread. More importantly, you can create your own examples. It is a shame that theory requires such front-loaded knowledge before you can even begin talking about applications of it.

One small little dig at the anti-theorists: why is it that people don't criticize threads like the one I linked to above? How often does anyone say, "I bet Hendrix didn't know his ass from a rectifier?"

i think jimi had a real understanding of electronics ( values) amplification pickups feedback and effects

also chord voicing

a master musician



true larry theory is like dental work the thought of it drills needles just freaks some people out

Sample Calculations:
SIL dB = 10log10 [1.6 x 10-6 W/cm2] –10log10 [1 x 10-16] ≈ [+2 dB -60 dB] –[-160 dB] = 102 dB ref 10-16 W/m2.
SPL dB = 20 log10 [2.55 x 101 dyn/cm2] -10 log10 [1 dyn/cm2] ≈ [+8 dB +20 dB] –[0 dB] = 28 dB ref 1 dyn/cm2 @ 4ft.
P W/mo2 = p2 ÷ ρ1∙cair = [(2.55 x 101 dyn/cm2)2 x 10-3 x 10-4] ÷ [(41.1551 N∙s/m3)] = 1.580 W/m2; where,
ρ1∙cair = 41.1551 N∙s/m3 is for the extant air-density in the subway-express station at the time of measurement


"Kilpatrick " has listed the decibel
ratings for various dental office instruments and equipment,
which amount to 70–92 dB for high-speed turbine
handpieces, 91 dB for ultrasonic cleaners, 86 dB for
ultrasonic scalers, 84 dB for stone mixers and 74 dB for
low-speed handpieces

It's easy larry! It's cool to obsess about tone, amps, guitars, strings, picks, mods, wiring, schematics, speakers, pedals, cables, etc.

It's not cool to obsess about actually playing the damn thing:)

And, just as there are guys that know a ton of theory and can't play for *****, there are just as many guys who know the math and can't make a good sounding amp or pedal to save their soul.

A spelling bee winner does not a good writer make.

Now you can take that last comment to the BANK!
:shock:

Unlike amp building, most other musical endeavors won't get you killed or seriously hurt if you don't know what you're doing. :wink:
