I have for sale stereo amplifer, based on Holton HPA-NXL200 R5.2 modules, precisely installed in custom build beautiful enclosure. I could say this is one of the nicest and solid built of this amplifier around. It`s superb sound desire top notch components, so amplifier consist of Hypex 1200A180 SMPS power supply, with additional 8x1000uF 50V Nichicon FG capacitor bank per channel, bypassed with Epcos MKP capacitor. There is additional push button circuit, so Hypex SMPS can be powered on/off with LED iluminated push button on front panel. Speaker DC protection is provided by Hifisonix DC protection with solid state switch instead of relay. Enclosure was specially made for this amplifier, based on Fischer SK56 heatsinks (CNC machined). All plates (except 10 mm front plate) is made from 3 mm aluminium plates and have extremely fine black power coated finish. For wiring speaker lines, Jantzen solid core wire was used. For power supply wiring, Jantzen stranded wire was used. Dimensions of amplifier are: 33x31x10 cm (WxDxH). Amplifier is in perfect operating condition. Input is provided with high quality Neutrik XLR terminals. Weight of this amplifier is a little over 7 kg, so not big deal with shipping.
Amplifier should put out around 80W/8 ohms and 120W/4 ohms, with current +-45Vdc power supply and 200mA bias per channel. Output power could be increased up to 150W/8 ohms, 250W/4 ohms with maximum recommended +-63Vdc voltage. Of coarse bias should be set up to lower level, due heat dissipation.

Agreed, stunning build. Exactly the kind of enclosure I'd like to make. I'll PM regarding custom heatsink machining
