Elekit TU8200 Tube Amp with additional upgrades.
In very good condition

Asking for RM2,400.00
Contact Peter 012-3820333

Tubes : 6L6GC x 2, 12BH7 x 2
Circuit automatically adjusts bias for the optimal operation of each tube
3 amplification modes (triode, pentode and ultra-linear) can be selected using PCB jumpers - Ultra linear (8W + 8W) / Triode (4W + 4W) / Pentode (8.2W + 8.2W)
FET ripple filter on board for power B for both left and right channels
Has overcurrent protection
High quality PCB with 70um copper traces (double regular thickness)
Audio Inputs : 2 x RCA and 1 x 3.5mm jack
Audio Outputs - Speaker impedance selector switch - 8-16Ω / 4-6.3Ω 
Headphone jack at front.

Parts upgrade done base on recommendation as per diy forum,

Component(s)Original ValueNew ValueComment
C22180μF/400V270-330μF/400VSignificantly less hum on headphone output. Max length = 36mm
C23,C2410μF/400V22μF/400VMore delay to B+ voltage, protecting tubes after switching on the amp. Max length = 36mm
C7,C8,C11,C1210μF/400V15μF/400VOptional - gives a bit more room. Max length = 20mm
C31,C323300μF/10V10000μF/10VHigher and better filtered DC heater voltage. Max length = 36mm
R640.47 OhmShort (0 Ohm)Cut off a pin of a resistor, bend it twice
D7DB107DB207Lower forward voltage drop. Required for driver update.
C34,C35220μF/16V220μF/16VOptional - gives better high frequency filtering of bias reference
C13,C14220μF/16V470μF/16VThe low ESR is very important
C33   220μF/16V330-470μF/16V   Better low frequency filtering of bias reference
