My first DIY build vacuum tube style Gainclone.
Bought the kit from EZamps website, its another Gainclone using LM3886 and the DIY step by step instructions are very easy to follow but I substituted the resistors with Vishay and Caps I used Cerafine also upgraded the NE5532 OPamp to LM4562. So far i'm impressed with this amp it sounded very good driving an 8 ohm ONIX XLS speakers, the detail, imaging and clarity on mid and highs are amazing.
Power Output: 4 ohms 50WRMS, 8 ohms 38WRMS
Bridge Power: 8 ohms 100WRMS
S/N Ratio: <-92dB below 1W, 8Hz-20kHz
Average DC Offset: <1mV (Tempco Compensated)
Frequency Response (-3dB points): 8-50kHz +/-0.1dB
Instantaneous DC Offset: 0.0009V
PCB: 4.2 x 3.0" Double sided, silkscreened
Heatsink: 2.38 x 4.56 x 0.9" Black Anodize 6061 Aluminum
