    Re: Tube Amplifiers

    Back in 1987 or 88 I sold my Quad II rig in order to buy my first PC, I wish I still had it
    The electrostatic speakers where awesome but you needed a large room because they had to be 3 feet away from the wall to get the bass to reflect properly.
    The picture on Wikipedia is just of one channel, there was an identical amp for the other.
    You would have to spend a big chunk of change to buy that system today.

    Quad II you can build at home, speakers probably not.

They're not bad; especially considering that they are the only item listed here not worth more than my car!

    I should say, though, that by no small margin my favourite mics have no tubes in them at all: They are Stephen Sank modified ribbon mics. They're abhorrently delicate and therefore never get taken out of the studio (I do some remote recordings from time to time...) but they (ribbon mics in general) are head and shoulders above even the Neumanns in a lot of applications. They need loads and loads and loads of clean gain, though, which usually rules out tube mic amps. :^)

    No tube amps, just solid state. Got a 3-yr-old Sony AV receiver for my amp. http://store.sony.com/p/STR-DH500/en/p/STRDH500

    My dusty, unused amateur radio station is a tube-type Drake B-line transmitter/receiver pair.
    FWIW, my 1500W lasers at work use a solid-state tube.

    Hoping to acquire a tube-type guitar amp someday...

    Both state solid and digital amps have come such a long way, that sometimes I forget and think there's no significant difference... until you hear a good tube amp again

    Best Regards.

    PS: these days I'm playing on a small practice amp: 40 watts Vox Valvetronix.
    We are in the Lewisville/McKinney area - we are about to start going to the jams again to test and show amps - find us on Facebook and friend us so you can keep up with us locally:

    If at first you don't succeed - just buy the company and tell them to make the one you want.

    Hmm, tube amps are really only worth the trouble if you make the tubes yourself. Otherwise, there is no physical reason why you cannot build the exact same thing using MOSFETs.

    However, for all you audiophiles, I have some wonderfully warm sounding low skin effect directional monster cables for sale...

    A number of amplifier companies tried marketing MOSFET guitar amplifiers and they never took off as a replacement for tubes although they are still in use . Weather they sound as good is subjective, but many guitar players want nothing to do with them . I owned a Fender solid state amplifier and it sounded much different than the tube amp I replaced it with and for me it was the right choice .
    Infinite diversity in infinite combination.

    Unfortunately there is a distinct and particular sound that can only be achieved with vacuum tubes.

    It is easy to build a circuit that simply amplifies the sound - simple.

    But to have a circuit that is actually part of the instrument - or that influences the sound is ways that solid state circuits cannot - is an experience that unless experienced personally - can never be duplicated.

    Some get close - but there really is no substitute for well made tube amplifiers for guitar, bass, music recording and music play back in the home.

    Vacuum tubes may seem old fashioned to some - but you can't get that sound without them.
    If at first you don't succeed - just buy the company and tell them to make the one you want.

    Years ago I had a Marshall 100w head and Marshall 4x12" speaker cab. monstrous rig. I'm now saving up for a Matamp GT40.
