Jan 31, 2014 · 2014-01-31 5:26 pm. #12. I simulated this 6SN7 SRPP with Hammond 125A as parafeed. It seems that the output impedance of the SRPP is too high for the primary inductance of 125A. The bass end begins to fall at some 100 Hz. Also the gain is a bit too low, some -1.5 dB. Only half of the primary is used.. The more exotic types, including the White cathode follower and the popular but misnamed SRPP, tend to be highly sensitive to component and tube variation. And both types of designs require large output capacitors that distort the sound and suffer high leakage currents; resulting in DC offsets which stress, and can even destroy, headphones. SRPP Headphone Amp (EE Tip #106) Mention tube amplifiers and many designers go depressive instantly over the thought of a suitable output transformer. The part will be in the history books forever as esoteric, bulky and expensive because, it says, it is designed and manufactured for a specific tube constellation and output power. Weighing in at a meaty 42kg, the Tulip SRPP is one of the heaviest integrated amplifiers in current production. There are good reasons for that high mass, though; a rigid chassis minimises the deleterious effects of flexing or resonating PCBs and this makes the amplifier more frequency stable as a result. In addition, the Tulip SRPP is rated at. We ended up with an Aikido 2006 design from TubeCad journal: Aikido Low-Impedance Headphone Amplifier which looks promising and can be configured in 3 configurations: 1) 12AY7 and 6H30 with feedback, and suitable for headphones from 16 ohm and up. 2) 6CG7 and 6H30 without feedback, high gain and suitable for headphones from 32 ohm and up..

Heater 6.3V, not more than 1.6A The board size: 125 x 80 mm. The kit does not contain scarce parts and winding units. . Sep 30, 2012 · Poddwatt: 5751 SRPP / Push-Pull EL84 (6BQ5) Tube Stereo Amplifier. This project is related to the other tube amplifier projects I have posted. It has more than a casual similarity to the first Push-Pull EL84 (6BQ5) Oddwatt project from nearly two years ago. Both tube amplifier projects use EL84 / 6BQ5 tubes and the earlier one used a ECC802S .... This common cathode amplifier for the input stage, SRPP amplifier circuit for the output level of the headphone amplifier circuit, through the theoretical calculation of the corresponding parameters, so that the amplifier can better drive the headset work. 6DJ8 SRPP circuit is Morgan Jones (Morgan Jones) designed tube headphone amplifier. SET 2A3 Tube Amp Schematic by Loftin-White (6SL7 SRPP input) - [3.5 Watts, SET, class-A]. 300B - directly heated power triode. Hello, my name is Andrey. Let me present you the Headphone Tube Amplifier.It is designed specifically for high impedance headphones, rated from 250 Ohms and higher (300-600 Ohms).Schematically, this is a SRPP cascade on russian 6N3P vacuum tubes. . They are found less often in instrument tube amps but Ampeg is one manufacturer who has used them for years as drivers for their SVT bass guitar amps . Other common names for this tube are ECC82 and ECC802 and the European special-quality E82CC and E182CC. Names found in military and industrial applications are 5814, 6189, and 7316.
SRPP pre- amplifier circuit and for the "long tail " type inverter circuit, so that the machine wide frequency response, low distortion. Tube : Shuguang 6P6P(6v6) × 4, 12AU7 × 2, 12AT7 × 2. Selection of the best super- linear type of push-pull amplifier circuit, the low-frequency driver enough, rich tone.
New SRPP Zen Headphone Amplifier After writing about both the new 12Vac SRPP in post 505 and single-ended MOSFET-based power amplifiers in my last post, the itch to actually build hybrid headphone amplifier based on the SRPP and the Zen single-ended power amplifier proved too hard to resist—so I laid out a PCB design and had them made.
I have built a number of line stages using the more common dual triodes in various output configurations -- cathode followers, SRPP , unity gain impedance buffers, etc. -- and while many sounded quite good (and a couple not so good), none.
