SET, push-pull, OTL? Duh? Huh?

post #1 of 2
Thread Starter 
I want to figure out what these mean exactly. I bought Traister's book and am about to start working on my Bottlehead Foreplay preamp. However, these terms befuddle me. I hate being a newbie. I want to be like you guys:

SuperSolderMan!
Able to make tall amps from a single schematic!
Master of molten lead!

I'm not going to be a newbie for long. There's too much to build and tweak! In the meantime, does anyone have time to put these terms in, ahem, English? Point me to a web site?

It isn't easy being green.

SET -single ended triode :that is a single tube running in class A (triode connected) performing all the amplifying duties

PUSH-PULL : one tube section is used to amplify the positive going signal,one tube the negative signal

OTL : Output Transformerless.Mens the output is direct connected (possibly through a capacitor) to the loudspeaker rather than through a matching transformer

hope this helps
