    This is the general consensus. Sounds like I can't go wrong with a 909. Plus it can be "upgraded" which is always appealing (to me).

    I'm thinking the synergy with the 63's will be obvious. Cheers

    OK Chris here is a left field suggestion, and not shabby in the slightest. Very much cheaper too, these are new amplifiers from excess stock.

    I use one of these as a stereo PA into my '57s, only bettered by Oli's Neurochrome

    If you have a suitable preamp there is a 30 second mod to bridge the controls on the front and raise SQ further.

    Like it Alan, like the price too.

    Gotta be worth a punt at that price. Look powerful enough to drive the 63's too. I have a tube pre-amp with adjustable impedance and outputs tailored for both tube and SS power amps so I'm sure I could make it work . . .

    I'll be home from work this evening and likely pull the trigger.

    Nice one.

    Yes. These are simply very good.

    I can only imagine the look on my face when Alan and I sat down to try this one.

    Alan's was a picture lmao.

    Bargain of the century in amplifier terms.

    I would also assess using 2x 306 instead, using one channel of each amp per speaker. The 306 has a
    virtual earth type psu per channel, which needless to say is a good invention of theirs, but stops you being
    able to use both channels of each amp per speaker, rather one channel per speaker, gives nice advantage
    for audio reproduction

    If you choose the 909, you will need to spend an hour or so applying good quality heatsink compound,
    (with cautions to directly touch the compound ) to assist transfer from the transistor aluminium bracket to the outer fins,

    Either amp, suit passive attenuators including opto coupling and are very good sounding, and will be a excellent choice with the 63';s
