T+A A 1230
T+A power amplifier in a compact format, drawing on the circuit philosophy of the A 1530 and offering substantial dynamic headroom.
Description
The T+A A 1230 is a power amplifier designed to be integrated into a separates-based hi-fi system, downstream of a preamplifier. Its casing stands out for its slim, compact format, breaking with the usual image of bulky power amplifiers.
Behind this understated presentation, the A 1230 draws on the same output stage philosophy and the same circuit technology as the brand's A 1530 model. It thus inherits the latter's wide-bandwidth character and speed of delivery. In terms of power reserves, the unit can deliver over 500 watts for brief periods, reflecting an ability to absorb the dynamic peaks of a musical signal without being caught off guard.
This type of amplifier is aimed at hi-fi installations built from separate components, where power amplification is entrusted to a dedicated unit rather than an integrated amplifier. The compact format of the A 1230 makes it a sensible choice for setups where space must remain limited, without giving up substantial power reserves for a track's most demanding passages.
What to check before buying used
On this power amplifier, the gain potentiometer should be tested across its full travel to check for crackling or channel dropout. The power supply capacitors, stressed by the stated power peaks, should be monitored after several years of use. Also check for the absence of hum at idle and that the speaker terminals are properly tightened, as these are sensitive on such a compact chassis.
