    Hey guys.. Not sure if you guys can be some help but still posting this doubt here...
    In case i have 2 tube amp heads.. can i run them in series?
    If yes then how do i connect them?
    I think thats how the mesa dual rectifier came into being... not sure though...
    can i have have my own dual rectifier?

    If I remember correctly, you don't, not unless there's a load connected to the first head. And you have to take the Pre-out/FX loop send/Line out to the input of the other. I don't know if people do this though.

    The history of the dual rectifier you can find on the internet.

    I thought you wanted to run them in series. That ABY is what most guitarists use to run a 2 amp set up. In parallel.

    first mesa dual rectifier is not mode up of 2 tube amps it is modeled on a slo 100 it 2 type of rectifiers in it i.e solid state and tube rectifiers the rectifiers convert ac to dc thats why is called dual recto plus the secret of that loose bottom end lies in the design of the amp not the rectifiers

    and ricky if you are thinking plugging 2 toob heads into one cab using an aby,buy em and go ahead you will **** the output transformer of the heads
    it is possible by switchbone not an aby i will explain in detail later why switchbone and aby which use the same principle are miles apart...gotta rush to teh loooo

    btw you may want to edit your thread's title
    when i read it i thought you were talking about preamp and poweramps

    I don't see where he said he wants to plug two amp heads parallel into one cab.

    Is there a cab which can take 2 inputs? i.e. from 2 independent amp heads?

    I'm confused now. What is it that you want to do?

    no but it can be made just take a cab and rewire it
    and add an extra jack plate and i second what thehundrethone said
    who's the noob now ricky?

    Okay if you're done self flagellating can you try and explain what it is you want to do so that I can get a clearer idea?

    Initially i wanted to use the 2 amps in series.. Input->amp1->amp2->output (if it is possible) .. Thats wat i meant my 2 stage amplification..

    Later I read somewhere that we can use 2 amps with single guitar using a ABY switch but i forgot to read that it doesn't applies to the amp heads until and unless they are connected to separate cabs.. Soon after posting this thread i used my brain and realized Wat a stupid question i have asked..
    I can use them if i buy another cabinet.. else not, is wat i inferred...

    The main problems running two amps into a single cab are:
    1. The output power of 2 amps combined could easily blow the speakers.
    2. Both amps have to be outputting to the speakers at all times or else one amp will blow (its transformer).
    3. You won't get the sound you're looking for because instead of each amp driving the speaker differently and the sounds then interacting, the speaker will be driven by the combined sound of both amps (possibly fixable using a multi speaker cab and hooking up separate speakers to separate heads).

    Hence 2 amp setups usually have a dedicated cab for each head.

    Using 2 amps is unnecessary unless you can actually afford the setup, place, transportation means and labour and are probably gigging everywhere...

    If you've understood the problem it's great, either ways i'll post the explanation below for everyone to understand, it can help out maybe some other beginner...

    The concept of an overdriven tone on a hot-rodded amp let say a dual rectifier (let's not discuss for now why it's called a dual rectifier) is just like connecting two overdrive pedals one after the other, so the the clipped signal gets clipped again and you get a thick saturated tone..but here these pedals are required to be connected to an amp so that you can hear something....

    Inside a dual rectifier amp the there are multiple preamp amp stages(around 3-5) where the signal clips and gets shaped musically and that signal is given to the output section...IT IS DEFINITELY NOT 2 AMPS ONE AFTER THE OTHER...

    Also if you have two tube amps, A/B/Y method is not applicable....because each amp must be connected to a speaker/load..
    So Either you'll need 2 speaker cabs, or one stereo speaker cab..but either ways each amp needs a speaker/load at the end....
