recently bought this one on an impulse buy from that auction site. a seller on the west coast who mentioned the following additional work on it:

“a complete DIY audio Dartzeel Assembled Power Amplifier NHB108 with aluminum chassis, upgraded capacitors, 4 pieces of SPRAGUE or BC 75V 39000UF capacitor, and Japan OMRON horn protection circuit and high power soft start.

It's one of my personal audio collection made by a professional audio recording engineer, all parts have been carefully selected, matched and test before assembled. all welding/soldering inside using silver tin wire.


Input Impedance: 100KΩ
Line Gain: +26dB
THD+N: -100dB(no load) -60dB (8Ω)
CrossTalk: - 125 dB
SNR: 115dB
Freq. Response: 10Hz ~ 20KHz
Max. RMS Power: 140W (8Ω) 200W (4Ω)
Volue: 440x330x160 (W*D*H)
G.W. 24kg. “

It is the version based on two pairs of complementary power transistors, for each channel.

For its purchase price it will not fail to offer great listening satisfaction, especially with speakers with timbral balance in the mid-high range and that are not excessively "brilliant".

nhb-108

i own a YAQIN ms 13, a Soundartist 200a, a DIY gainclone 2x60 watts and a nhb-108 clone
the NHB is certainly on top similar to the YAQIN
i am not capable to write all the poetry about sound "muddy, harmonic, 3 dimensional" etc...
i can only say that this $847.07 expense (including shipping) was worth it TO ME!
