PS-100 power supply - compact design, huge sound



One of the great thing about the march of technology is the increased superiority of electrolytic caps. These new caps are much smaller and and at the same time they have higher performance. It’s very positive paradigm shift. Look at the original caps in the Hafler DH-2XX series and then look at the same value cap beside it - amazing! These technology innovations have lead to much smaller power supply size in modern electronics. The PS-100 installs in a small space of 4.25” x 1.75” x approximately 3.5” high depending on your capacitor choice. Diode technology has greatly improved too. The PS-100 uses the same 22A/600V soft-recovery power rectifier as the PS-200. It’s a great sounding rectifier far exceeding the performance and sound quality of the original Hafler part and every other part we’ve heard. The rectifier has a metal backing that can be mounted against the chassis for heatsinking without making provision for electrical isolation. The PS-100 mounts easily and compactly on four standoff mounts. PS-100 has a sound of delicacy and yet big, big power and dynamics from a compact package! See the PS-100 installation instructions here.

>PS-100 “BARE” Kit: Same PCB as above accommodates all caps except Mundorf. Kit includes PS-100 PCB with all mounting hardware then install your favorite parts: $39/ea, instructions included   Optional: The rectifier form factor is unusual making use of other rectifiers complicated, so add $20 for 1 - HyperFred rectifier, clamp and hardware


Major Versastility: PS-100 supports standard 2-pin Snap-In caps, most 4-pin standard Snap-In caps and Jensen 4-pole capacitors. It gives you an almost infinite choice of caps up to 40mm size. Use the bare PS-100 board for your projects including custom preamp power supplies.


For your Hafler DH-500/XL-600 and other larger amps we recommend the PS-500J or the PS-500V2.




PS-200 - Versatile dual-mono power supply




Why we developed the PS-200:


Previously our dual-mono mods were very labor intensive. We sold these in a kit form too, but for the first time builder it was complex and very time consuming to install. It all fit really tightly into the amps too - no room for errors. Now you can easily install it yourself . With the PS-200 there is plenty of room after installation. Our large TP-202 toroidal transformer is no longer a challenge to position and install with the dual-mono configuration for Hafler 200 series amps. The PS-200 will allow you to improve neatness of installation, shorten current paths due to "inverted" capacitors which is good, improve sound quality and lower the price for high-performance dual-mono sound. Life is good!




PS-200 Board Features:



Our standard capacitor is 15,000uF/80V for use in DH-200/DH-220/XL-280. The higher voltage requirements of the DH-500 and XL-600 amps are served with a 10,000uF/100V capacitor.

PS-200 layout also accommodates four-pole Jensen(35mm) - has fool-proof one way installation, 6800uF/100V up to 15,000uF/63V. Jensen caps are used exclusively for the PS-200J model. 

Jensen is a Danish company specializing in high reliability industrial electronic parts and an impressive line of audiophile quality capacitors and inductors. 


The PS-200 bare board is made in USA. IXYS is a Silicon Valley company with worldwide operations.



What you can do with the PS-200:


Turn your Hafler DH-200, DH-220, DH-500 or XL-280/600 into a more musically satisfying product with improved imaging, crispness and dynamics. We have installed PS-200 boards into other amplifiers too. A number of Adcom owners have added PS-200 boards. See some more examples here

POWER SUPPLIES FOR HAFLER DH-500 or XL-600 amplifiers

OR LARGER CUSTOM MOD AMPLIFIERS


NEW!!! PS-500J POWER SUPPLY with JENSEN 4-POLE CAPS


The Need: Putting Jensen caps in the DH-500 was never simple if you go all the way with eight of them. We had to fit two of our PS-200J boards in the amp and the fit was super tight with no margin for placement error. It was tough enough for us and we did cringe when someone wanted to install his own.

 

Now: There are no fit issues with the PS-500J, a single board with simpler, faster installation. Now guys go ahead and install it yourself, no cringing here. We get to reduce the pricing by over $100 compared to the old way with the two separate boards. Good all around.


Big Bonus: We love the sound of the CRC power supply which is incorporated into our new PA-6 driver boards. You can also do that with a ‘main’ power supply with as much or more benefit. Your PS-500J power supply board is a CRC design with four independent power supplies, two (+) plus and two (-) minus taps.


The Sound: If you think Jensen caps are smooth, silky, sweetly extended at the top and at the same time exciting you’ll get that to the max. Another bonus is a more tuneful solid bass than you expected.


PS-500J power supply: $849 kit, $999 installed - KIT INCLUDES (1) PS-500J circuit board with all mounting hardware, (8) Jensen 6800uF/100V 4-pole caps, (2) 22A/600V premium rectifiers with mounting hdwe, (4) radial mount 10 Watt resistors, (4) small bleeder resistors, solder, instructions

PS-500V2B power supply - 88,000uF and it sounds like it!



You have a big amp and you want to maximize the sense of power. Maybe you need maximum muscle to drive a ‘difficult’ speaker. You want a ‘dual-mono’ sound quality.* You want a powerful, yet liquid and delicate quality from the power rectifiers. We knew what to do. We designed the PS-500V2B to fill those desires. We could go on with a dozen more buzz words but you just want no-nonsense, big power sound and this is the answer. The PS-500V2B is civilized big power.



Features: Solder fillable tracks, Clean simple installation, Superbly sweet soft-recovery rectifier

>PS-500V2B (Hafler DH-500, XL-600), kit: $279 with 22,000uF/100V caps, $130 for a typical installation - Kit includes PS-500V2 PCB, 4-22,000uF/100V caps, 2 - HyperFred soft-recovery rectifiers with clamping hardware, heavy gauge wire, solder, all mounting hardware and instructions.

*Full, true dual-mono operation can be achieved with our TP-500 stacked toroid power transformer modification.  


>PS-500V2B "BARE" kit: PCB with full mounting hardware, install your own parts: $59/ea, instructions included. PS-500V2 PCB supports 2-pin, 4-pin and 5-pin snap-in capacitors. Optional: The rectifier form factor is unusual, so add $35 for 2 - HyperFred rectifiers, 2 - mounting clips and hardware


Note: Amplifier is not included with this kit.


POSSIBLE OPTIONS: If you have efficient speakers and listen at modest levels in a normal sized room then a lot of capacitance may not be required. The options below allow for a smaller budget or, in the case of the Jensen caps, a taste of luxury at a lesser cost than the PS-500J.


>PS-200 (DH-500, XL-600), kit: $229 with 4 - premium 10KuF/100V caps, $130 for typical installation  —  For a stout, robust gain in sense of power see the PS-500V2B above.

>PS-200J (DH-500, XL-600) kit: $439 with superb Jensen 6.8KuF/100V 4-pole caps, add $130 for typical installation For the all-out Jensen experience see the PS-500J above.
