A goofy analogy to transistor circuits

[saturated]

I got to thinking that maybe they are like air hockey
Like DC is the air
You have to have it for the puck to ride on
And the signal is the puck

Or maybe not   

[saturated]

To take this a step 🪜 further 

Make the transition to real ice hockey 🏑🏒 then the DC is ice

So if we need to fix the DC and get it in order then we need the Zamboni 

Got a problem with your amp ?

Summon the GREAT ZAMBONI
