  • Transformerless tube amps! WOW!!!

    http://www.vikingamps.com/

    It's amazing, I get off this board and I start to actually learn things. Found this over on the webervst.com boards, which are actually some of the best I've found for getting good honest info about anything OTHER than effects. They're just not quite as stomper crazy over there.

    Oh yeah, and check this crazy thing out:

      err...

      how is that done?

      you need a transformer to up the b+ to something that can heat the plates, and you need the output tranny coupled as well

        Julius Futterman pioneered a type of amplifier known as "output transformerless" (OTL). These forego the typical output transformer by paralleling (electrically connecting and operating side-by-side) perhaps one dozen or more output tubes in an attempt to reduce effective plate resistance and more closely match it with speaker impedances (typically 8 ohms). This design and its various incarnations tend to require numerous tubes, run hot, and because they attempt to match impedances in a way fundamentally different from a transformer, they often have a unique sound quality



        ahhhhhhhhh

        but what abooot the b+ ...

            My interest in these transformerless tube amps is peaked.

            How much do they run? You'd think not having transformers would bring the cost down a bit.

              OPTIONS

              * Caddock Resistor package $1000
              * Power Supply Boost (uses custom built filter caps for MA-2) $2200
              * V-CAP Teflon coupling caps $500
              * A/AB switch (useful for home theatre and parties...does not affect class A sound) $700



              And to think we get all existential about $250 for a fuzz pedal. We don't have anything on the real audiophiles. Just look up the prices for high-end interconnects and speaker wire some day, it's astounding

                  And for the budget-minded (ie, dirt poor like me) there's the Zvex iMPAMP. Zach builds badass pedals so you know this little bugger is no different. Tube audio gear has been around for a long time guys, it's long overdue for guitarists to walk the tube walk and use tubes in everything involving music, not just guitar amps.

                  Around $700 I think. Click the pic.



                  Hell you can even get motherboards for your PC with a tube (they need to put tubes on a soundcard though, I sure ain't giving up my motherboard).

                      Yeah, I wanna know more about the viking amp.

                        There's soundclips on the page I posted for the Viking stuff. Nothing in the reviews on HC though.

                          It's Always hard to determine from clips, but did anyone else think the samples were a little bright and thin sounding?

                            Yeah I thought the same thing. Clips do suck, usually.

                              I have an old Silvertone (Danelectro) Amp in Case and the amp is transformerless, the voltages all add up to 120V. About 50 years old, not so new
