AMP15 Detail

AMP15 is based on the TA3020 chip, like our Truepath. This is a well proven chip which is hole mounted and has a large heat sinking capacity in itself, here in an all new design.

This amp is designed for high voltages, up to +/-60V, with moderate output currents. It is best suited for relatively high impedance speakers like 8 or 16 ohms. It can be used for lower impedance loads like 4 ohms if the supply voltage is limited to around +/-35V.

The output stage uses dual FETs in 5-pin TO-220 package. These FETs are very easy driven and with the very compact output section design of AMP15 produce a very clean output, low THD+N over the whole frequency range. The output filter consists of dual very linear audio optimized inductors, two in parallel, for low current load on each. They are followed by polypropylene filter capacitors.

On the board there is a high quality rectifier and two massive bulk capacitors, providing clean power to the amp. Regulators for "housekeeping" voltages, +5V and VN10, are on the board. 

Our measurements show that this amp has THD+N which is just as low as our AMP11, i.e. Around 0,007% at 1kHz, and maintains very good performance over the frequency range.

An IC socket for the TA3020 is now included in the kit.

What is needed for a completed amp depends on you application, but here is an outline

• A transformer, normally a dual toroid transformer
• A casing. As the heat dissipation is low, the casing bottom is usually enough as a heat sink
• Hookup wires, connectors, fuse holder, power switch
