The power supply is the heart of your power amplifier. It must provide widely varying current outputs to the speaker load, i.e. difficult to drive speakers are handled properly at all frequencies. Only the finest parts providing instantaneous output current over the whole audio band can hope to offer a truly faithful recreation of the amplifier’s music input.
TP-202 TOROIDAL POWER TRANSFORMER
For Hafler DH-200/220 or XL-280 or custom project:
TP-202 - similar to picture at left*, is a potent toroid power transformer with many important features for ‘music lover performance.
Technology serves sound:
- More dynamic quality than the original old-style transformer >far more efficient
- High efficiency means quick recharge ability > instantaneous, dynamic sound
- High efficiency - unlike toasty original power transformer it barely runs above room temperature, your amp stays cooler
- PREMIUM FEATURE - External magnetic field is very tightly contained by the external metal band shield minimizing hum/buzz noise
- PREMIUM FEATURE - Internal electrostatic shield shunts higher frequency power line noise to ground via that purple wire - you enjoy a sweet, liquid quality
The Sound:
- You will notice greater heft or air moving ability, more feeling of bass energy in your chest.
- The bass line will be more solid and palpable, a dynamic experience closer to reality.
- You will experience better pitch definition in the bottom.
- The background is ‘blacker’, enjoy quieter soundstage, a rich unraveling of complex passages emerges
- Instruments will seem to "pop out" of a more silent background with greater focus and clarity.
- Dynamic range is not only wider at high power levels, but even guitar or flute solos seem more dynamic.
TP-202: KIT: $139/kit, necessary hardware is included, INSTALLED: $195 in most amplifiers
*transformer appearance may vary
How to use it: TP-202 can replace the original transformer for a sonic boost appreciated even with efficient speakers. In addition, TP-202 helps you construct a seriously natural sounding power supply with our new PS-200SR power supply or in concert an original Dual-Mono PS-200 board, within the chassis of your Hafler DH-200/220 or XL-280. It’s seriously fun sound.
Installer Notes: You will need to use a power drill to make the center hole for the transformer bolt (supplied). This will require a 1/4"(or slightly larger) hole. DH-200/220 requires that the fuse holders be moved away from the center of the amp, a tiny bit, if you are going to use the original Hafler boards. Our PA-XX series front-end boards have PCB mounted fuses so that this is not an issue if you are installing or have previously installed these terrific circuit boards in your amp, i.e. you remove the fuse holders completely.
TP-500 TOROIDAL POWER TRANSFORMERS
For Hafler DH-500, XL-600, or custom project:
TP-500 is a pair of 500 Watt toroid power transformers. These transformers will indeed fit when stacked on top of each other. The original transformer was rated at about 680 Watts to be generous, so this upgrade to 1000 Watts is significant. Not only that but you can easily fashion a dual-mono power supply with the PS-200/PS-500V2 circuit.
For sound quality refer to TP-200 transformer above.
TP-500(pair of 500 Watt toroids) > $269/kit, necessary hardware is included, $349 installed. Transformer appearance* may differ from illustration.
How to use it:
- TP-500 can be used with one pair of filter caps, either the stock ones or the LC-500 caps shown below. Both transformers are paralleled for this purpose.
- You can install the TP-500 with the dual-mono PS-500V2 to make a potent, totally dual-mono power supply. You simply connect each power transformer to the separate rectifier/capacitor system on the dual-mono PS-200/500 single PC board.
Installer Notes: You will need to use a power drill to make the center hole for the transformer bolt (supplied). This will require a 1/4 - 5/16" hole.
