Willsenton R8 EL34B Integrated Tube Amplifier(used)

My R8 originally came with KT88 power tubes. 

It has been upgraded with 4 balanced units of Tung Sol EL34B power tubes. The pre-amp section has also been upgraded to a pair of Tung Sol 6SL7GT. This combination has given the R8 more control in bass and better definition in imaging and soundstage. 

In addition to the new Tung Sol tubes, this package also comes with:-
1. 4 units of Willsenton KT88 power tubes
2. 2 units of Willsenton 6SL7 pre-amp tubes
3. 2 balanced units of Melz 6H9C russian 1950's pre-amp tubes which is the exact equivalent to the 6SL7GT.
4. Original metal remote
5. Original box & manual

Price: RM5590  RM4990
Condition: 9/10

No shipping because of its sheer weight = 30kg
I'm in Ampang, Selangor area.
There a lot positive reviews online and on You Tube. Some examples are:

Enjoy the Music.com
It delivers a warm, rich presentation from only 45 Watts. Tarun's ProAc bookshelf loudspeakers are not the easiest load in the world but the R8 took charge and created a surprisingly wide and deep soundstage with excellent layers of detail.


Steve Huff Reviews:
The Willsenton R8 Integrated Tube Amplifier is a NO BRAINER BUY.
Bottom line: Not only the best of the Chinese tube amps I have heard, one of the most enjoyable integrated amps I have ever heard or owned. It’s that good and let’s you get into high end tube sound for not so high end money. The real deal. 

Specs as follows:-
• Pure hand-made, Point to point manual welding.
• Use a square power transformer specially developed for this machine.
• The output transformer uses two high quality wideband EI output transformers.
• The preamp stage uses one 6SN7 for power supply filtering.
• The voltage amplification stage and the driver stage use two pairs of 6SL7 and 6SN7 tubes, respectively.
• The power amp stage uses four KT88/6550/EL34 tubes for class AB Push-pull power amplification.
• Triode and ultra-linear selection are available. The triode works in a soft, pure-and sleek sound, suitable for listening to vocals, strings and other types of music. Ultra-linear working mode, sound-tone open, unrestrained, good momentum, suitable for enjoying big scenes, big dynamics and other types of music.
• External independent BIAS-ADJ current display header. Adjustment and BIAS meter monitoring function keeps the best state of the power tube at all times.
• External EL34/KT88 tube selection function, easy to replace different types of tubes, adding endless fun.
• Infrared full-featured remote control.
• Use thick silver plated signal leads.
• With pure post-level function, it can be connected to independent preamplifier signal input.
• Power on mute delay function, soft-start feature to prolong tube life (about 30 seconds).
• Select Japanese ALPS high-end motor potentiometer.
• Easy-to-install plug-in tube cage cover.
