before the amp Dyno, how did company's come up with birthsheets

[ChevyBoy95]

Just because there wasnt an amp dyno doesnt mean there werent the tools to replicate a similar result. Resistive loads are nothing new, oscilloscopes are nothing new, and tools to measure ACA and ACV are also nothing new.

The dyno was just one of the first convenient and relatively cheap tools to do it quickly and efficiently.

edit: now is this how the other companies back then did it, idk, but the technology was there.

That power cube is pretty cool. The PDF only showed companies with big dollars being able to afford it. After that challenge who wouldn't want a T3002? I might have to get one on ebay now just because.

Surprised you don't have one already with how under rated it is and the fact it's a Rockford price if history. Everyone says you have everything Rockford, a collector of.Rockford goodness lol.

There you go.

I do need to add one to my pile. I dont call it a collection cause I always tell myself I'm gonna use the amps I buy :-) Probably get one around tax return time

the ones on amazon aren't bad for the price. i just saw your thread about the rockford money clip and now im trying to find one lol. so far i havent found one for sale but ive seen the pic of yours and a pic of a different one. most likely wont find one to buy anytime soon though.

Every internet famous company now a days use the trusted word fro their supplier to say what their ratings are.

Companies could use something like the Audio Precision 2700. http://www.ap.com/products/2700 Typically paired with Inductive load resistor(s)
