300b tube amp11/19/2023 Fan favorite What Is Mastering? What Happens When An Album Is Remastered? is also still available as well. If you are interested in further exploring the analog realm, the Guide To Buying A Turntable (and records) might point you in the right direction. Season 4 highlights include Joseph Audio, Pro-Ject Turntables, and Rob Watts. One can still download this season’s educational show with TOP’s Beginners Primer To High Fidelity Digital Audio alongside the latest on Two-Way Speaker Design. The finale from season 5 includes the yearly “best of awards” and you can also find episodes covering British HiFi, Subwoofers/Setup/Tips, and the how to: Budgeting From Entry Level To High End. Previous episodes include Our We Heading Towards a Tube Shortage?, interviews, how to’s and more from audio’s greatest talents, including Michael Fremer and their picks for products of the season, another interesting conversation about the History Of The BBC’s LS3/5a Loudspeaker, A Beginner’s Guide To Tube Amplifiers and A View From The Booth: Reference Systems, Accuracy & Why Audiophiles Love Jazz So Much: including rare interview with the late audio legend engineer Al Schmitt. The Occasional Podcast is closing up their seventh season. Why is the 300b so common in audiophile tube amplifier designs? What about the 300b makes it unique among the many options available to amp makers? The Occasional Podcast explores everything you would ever want to know about this direct heated triode, including usage, benefits, drawbacks and the current state of pricing and supply. On this week’s episode of The Occasional Podcast Gary Dews of Border Patrol Audio Electronics joins the conversation to help educate and explore one of the most wondrous of audiophile tubes. Of the tube chosen for this sacred task, there is perhaps no tube revered more than the 300b. No manual adjustment is necessary.īT compatible audio input is available for wireless convenience.It is no surprise that hifi lovers ofter gravitate towards tube amplification despite some of its innate drawbacks. Microprocessors automatically bias the 300B tube pair each time the amplifier is powered on. Up to six (6) source devices can be connected during amplifier operation. The included infrared remote control allows for quick adjustment of amplifier settings such as input levels, balance, and display dimming. The display also shows settings which can be adjusted by the included remote control. Single impedance transformers maintain lower winding capacitance normally vitiated with multiple tap transformers.Ī bright and easy to read color display shows the selected input, attenuator level, and VU meter. This feature is unique to the 91E Integrated Amplifier and allows users to match speaker impedance for improved fidelity. The standard 8-ohm transformer block can be interchanged with the optional 4-ohm or 16-ohm version. The attenuator consists of only discrete resistors in a ladder configuration that are switched in and out of circuit to produce a logarithmic attenuation of the output signal. The excess of common large output transformers and associated hysteresis is eliminated, and as a result, lush detail in the midrange and masterfully articulated upper and lower frequencies are revealed.Ī stepped logarithmic attenuator is used to mimic the response of human hearing. This new level of performance is reached by using a fully linear, steered current source ( US Patent 10256776) controlled exclusively by the tube’s output voltage.
