Hmm an amp question

[-Loco-]

omgaiguzogz hi guyz im like nu to thu forum nd wna b like u guiz.


sorry i felt the need to be even more retarded than my current state.


ANYWAY.

Right - triple rec, if i take out some of my 6l6's the amp will be quieter and can still run..right? so does that mean i can drive the pre-amp harder? and does that mean i could potentially have 2 power amp tubes running with all the pre-amps...run em hot and loud - to a volume where im actually going to start getting something out of the triple rec as its a fucking loud bastard with a tiny touch of the master dial...and then i might ACTUALLY be able to mic this amp and record with it?

this is probably a nice little question for metaltastic to answer

and i'm probably being a noob. Thanks guys!

Haha, yup, time for me to make an appearance - first off, the 6L6's are power tubes, so they have no effect on the preamp; the only way to run the preamp harder is to turn up the gain knob! Also, unfortuately, apparently pulling two tubes out of the triple recs doesn't work quite as well as on 100 watt amps, here's a quote from a thread about the subject over at the Boogie Board:

You can do it, but there is a downside.

The thing about pulling tubes is that it ends up changing the output transformer impedance. With a Dual, it's a 1:2 ratio. Pulling 2 tubes doubles the impedance, which doubles the speaker tap impedance also. The 4 ohm tap becomes 8, 8 becomes 16.

With a Triple, it's more of a 1:3 ratio. Pulling 2 tubes would increase the OT impedance by 1/3. So the speaker taps would change by that same ratio. The 4 ohm tap would become 5.33 ohms, 8 would become 10.67. That means you will have a mismatched speaker load with any speaker.

It's not a huge problem, but would cause the tubes to wear faster.

So if it's too loud for you (and I can easily imagine, I know it'd be too loud for me!), I'd strongly suggest selling it for a Dual! (or better yet, a Roadster, I'm about to leave to compare my 2 ch. to one, updates tonight! )

I am hanging around for the comparison, you need to convince me to grab a mesa, I hope the roadster is better than the recto. I dont know why I want one, I just do!:hotjump:

Haha, well here it is guys, see what you think!
