Primal Amplifier Questions

[zanshin777]

1) I've heard that Slash's signature amp has 3*ECC83 preamp valve and 4*EL34 power amp valve and it is a one chanelled amp
so all that power goes in a one chanell ?
however TSL100 model has the same spefication but it has 2 chanell
then does the power divide to two chanel ? (does all the power go the chanel you use)

2) when a amp has 2 el84 power amp instead of 4 does it give me lesser sustain ? (at the same setting)

3) What does it change the speaker get bigger ?

4) What does it change it's 4*12 instead of 2*12 ?

lots of 100w marshall amps have three preamp and four power tubes. the tsl has multiple preamp channels but uses the same tubes for all the channels just with different paths to get there.

the number of power amp tubes will effect the volume output of the amp not really the sustain

im not sure what you are asking in 3

having two extra speakers will push more air but there are lots of variables when it comes to cabinets including size, materials, closed vs open vs ported, type of speaker etc..

The "channel" is the preamp. That signal feeds the power section. There's only one power section (for most amps).

The amount of "sustain" is more dependent on your overall gain level than how many output tubes or how much power you're pushing.

When the speaker gets bigger it pushes more air- it makes more sound. However, as the speaker gets bigger, it looses responsiveness. It takes more time and effort to move the cone to move the more air.

A 4x12 has twice the speaker space- you're pushing twice as much air. In a 4x12 you also have a larger interior space, larger baffle, larger enclosure (back and sides) all vibrate differently. Add to that the "coupling effect" of the speakers in proximity to each other. Generally a 4x12 will be louder and "bigger" sounding than a 2x12.
