T+A Amplifiers

PS 3000 HV

External power supply. 1,200 VA. 240,000 uF.

The PS 3000 HV is T+A's dedicated external power supply for the HV series — a 1,200 VA transformer unit that doubles the reservoir capacity of the connected amplifier to 240,000 uF and delivers up to 1,200 Joules of energy almost without time delay. Its encapsulated toroidal transformer is potted in an aluminum ring with insulating compound, mounted on a 10 mm base plate with bi-directional resonance absorbers to eliminate mechanical vibration. Low-inductivity capacitors with parallel wiring reduce internal resistance to near zero. Connects via PowerLink M 23 high-current connectors and is entirely controlled by the host amplifier via HLink bus. A VU meter displays either power supply voltage or current delivered in real time.

Key Features

1,200 VA / 240,000 uF

Doubles the reservoir capacity of the A 3000 HV or PA 3100 HV, delivering up to 1,200 Joules of energy on demand.

Encapsulated Toroidal Transformer

Potted in aluminum with insulating compound, mounted on 10 mm base plate with bi-directional resonance absorbers — zero mechanical vibration.

PowerLink M 23 Connection

High-current M 23 connectors and HLink bus control — the PS 3000 HV is entirely managed by the connected amplifier.

VU Monitoring

Large VU meter configurable to display real-time power supply voltage or current delivered to the amplifier.

Technologies Inside

High Voltage Technology

Tube linearity. Transistor power.

T+A's HV amplifiers operate at dramatically higher voltages than conventional designs — up to 100V in preamplifiers and 360V in power amplifiers. This forces the audio signal to exercise less than 20% of each transistor's operating curve, staying in the most linear region. The result is tube-like linearity and naturalness with transistor power, bandwidth, and reliability — virtually no negative feedback required. Built entirely from discrete components with individually selected audio J-FET transistors, encapsulated gold-contact relays, and precision discrete resistor volume control.

Most solid-state amplifiers operate their transistors across a wide portion of their transfer characteristic, which introduces non-linearity that must be corrected with large amounts of negative feedback — a technique that reduces distortion on paper but can compress dynamics and add its own sonic signature. T+A's approach is fundamentally different: by raising the supply voltage to 360V in power amplifiers (compared to the typical 60–80V), the music signal uses only the most linear 20% of each transistor's operating curve — the region where a transistor behaves almost identically to a vacuum tube. This means negative feedback can be reduced to near-zero levels, preserving the signal's original dynamics, micro-detail, and spatial information. Every HV circuit is built from discrete components rather than integrated circuits: individually selected and matched audio-grade J-FET transistors, hermetically sealed gold-contact relays for signal switching, and a precision discrete resistor ladder for volume control that maintains perfect channel balance and signal purity at every level.

HV Series

The absolute reference.

T+A's flagship amplifiers operate at dramatically higher voltages than conventional designs — up to 360V in power stages. This forces the audio signal into the most linear region of each transistor's operating curve, achieving tube-like naturalness with solid-state power and bandwidth. Fully discrete construction with individually selected J-FET transistors, gold-contact relay switching, and double-mono architecture. The pinnacle of T+A engineering.
