Headphones Tube Amplifiers

Tube amplifiers Single-Ended (Class A) & Push-Pull (Class AB) Output Transformerless (OTL)

Virtus-300B

Headphones Tube Amplifier

OTL-SE (Class A) Dual Mono

Virtus-300B – OTL Single Ended headphone amplifier (without output transformer, class A) in the Dual Mono architecture. The use of 300B triodes in an efficient work system in the power stage allows the device to work with many dynamic headphone models. Optimal impedance matching (headphone resistance) amplifier reaches at 200 Ohm, but thanks to the relatively high output power (OTL mode), the equipment provides 2 x 1W headphones

Type: tube, class A, triode, OLT

Amplitude of input voltage: 2 V – 12 V (max)

Input impedance: 50kΩ

Output power at 200Ω load:

2 x 1W

Anode voltage: 250 VDC

Heater voltage: 6.3 VDC, 5 VDC

Power consumption: 200W

HPA Master Pro

Headphones Tube Amplifier

OTL-SE (class A)

HPA Master PRO – OTL Single Ended headphone amplifier (without output transformer, class A) with preamplifier function for linear signals. This is an extensive version of the HPA Master headphone amplifier. The use of dual 6N6P triodes in the power stage, which are connected in parallel in each channel, enables the device to work with many dynamic headphone models. 6922 EHG, equivalent to the popular ECC88, is used as the standard driver tube.

Amplifier type: tube, class A, triode, OTL

Output power for 34Ω load impedance: 2 x 300mW

Output power: 2 x 300mW / 34 Ω

Anode voltage: 200 VDC

Heater voltage: 6.3 VAC

Lamps: 1 x 6922 EHG, 2 x 6N6P

Load impedance range: 24Ω – 400Ω

Inputs: 3 x RCA Stereo

Outputs: 1 x TRS Stereo, 2 x RCA Stereo

Virtus-01

Headphones Tube Amplifier

OTL-SE (Class A) Dual Mono

Virtus-01- OTL Single Ended headphone tube amplifier (without output transformer, class A) in the Dual Mono architecture. The use of the KT88 / KT120 / KT150 tetrode tube allows the device to work with many dynamic headphone models as well as some planar headset models. As standard, 6922 EHG or equivalent of the popular ECC88 are used as standard tube.

Type: tube, class A, triode, tetrode, OTL

Amplitude of input voltage: 2 V – 12 V (max)

Output power for 85Ω load impedance:

2 x 1W (KT88);

2 x 1.2W (KT120);

2 x 1.5W (KT150)

Anode voltage: 250 VDC

Heater voltage: 6.3 VAC, 6.3 VDC

Power consumption: 200W

HPA Master

Headphones Tube Amplifier

OTL-SE (class A)

HPA Master – headphone amplifier OTL Single Ended (without output transformer, class A). This is the basic model in the offer of White Bird Amplification headphone amplifiers.
