FS: Class D Audio SDS-254 amplifier and power supply

Class D Audio SDS-254 amplifier module with upgraded power supply and transformer. This setup includes the SDS-254 amplifier module (125 watts into 8 ohms, 250 watts into 4 ohms), plus the power supply and 400VA transformer. The power supply is an upgrade from the standard ClassDAudio.com supply, using 48,000 mfds of 105 degree Panasonics caps (bypassed with a 0.33mdf polypropylene) along with MUR1560G rectifier diodes. This supply provides 60 joules vs the 35 joules for the stock supply.

I built and used this setup lightly for about 3 years, and recently removed it to build a higher powered amp into my chassis. This setup was working great before recently being disassembled, but is sold as-is because I can’t be responsible for what the buyer does with it. This setup is similar to the Class D Audio SDS-250 kit currently being sold. You’ll need to supply a case and input/output connectors to have a functioning amp. Note that I have dispensed with the variable gain controls and wired it for a fixed gain of 26.44dB. Actual shipping costs to be paid by the buyer, from 06905, local pickup welcome. It will weigh about 12 pounds packed. $200 plus shipping.

Note: I would NOT recommend this for a novice, but rather a builder with some electronics experience.
