Ming Da MC-3008-A2 Mono Blocks

[88man]

Very curious, can anyone comment on the sound and quality of the Ming Da MC-3008-A2 40W Mono Blocks from Pacific Valve?...

I can't find any reviews. The tube topology is (2)12AX7, (2)12AU7, (2)300B, (2)805 tubes. I don't have a schematic, but is it a good design with decent OPT?...

I am going to run it as a integrated amp with a Cambridge Audio CDP 640v2. Speakers are Paradigm S40 v3.

Thanks Guys!

Hello,
If you still want info about this amp Lampizator site have a nice review about this SET, scroll down the page:
ming-da

I also like this Ming-DA 805 SET looks a great amp, lots of potential for good sound.
I got this information in contact with Mr.Lukasz:
1- What security protection this amp have(B+ fuses, micro process etc)??
No B+ fuse, no micro. It is basic.
2- This amp are zero neg.feedback or use alot of NFB ??
It has some feedback, I dont know how much but in my opinion it is not necessary at all.
3- What is the Net Weight of this monoblock ??
I dont know but maybe USA quotes gross with packing.They are heavy, I think 25 not 30 Kilos.
I would use 300B from Electro Harmonic Gold series (russia). Best bang for the buck.
The 805's are good tubes. It is VERY good value amp and it is very well made. First class really/.

I got this information in contact with the Ming-Da lady:
1- The heating of the four tubes are AC or DC?
.. The heating for 805: DC, 300B or 2A3C: DC, 12AX7 and 12AU7: AC.
2- How is the BIAS adjustment of the 300B and 805 tubes??
.. You can use a multimeter to contact the 1 ohm/5W resistor near 805 tube and then
adjust the 33K adjustable resistor to make the multimeter to show 0.1Volt
3- This amp are zero NegativeFeedback? Or how much NFB it has?
.. There is Negative Feedback and the NFB could only be known after it is tested.
4- The site index - Pacific Valve are your authorized dealer??
.. Yes, Pacificvalve is our authorized dealer and you won't get a fake one from him.
5- On a PacificValve YouTube.com video the 805 cathode start emit light instantly after
power on, in a clear lighted room. I wonder If this amp has soft start?
.. Yes, the amp has soft start.
6- PacificValve say the MC3008(2A version) they sell are a special and better version for the US market.
This is true??
.. MC3008-A is already very good.
7- This MingDA MC3008A amp is a safe amp when a tube fail on the fly?
.. It is safe. If there is something wrong with the tubes, the biggest problem is no sound from amp.
The amp will not burn you.
8- Iam ask it because I was told this amp have no one security on all the tubes, nor B+ fuses,
no Short-Circuit fuses, no micro-processed monitoring etc... Do you confirm this?
.. The fuse in the power plug will disconnect the machine by itself if a short-cut happens in the amp.
When the amplifier is working, please do not leave for a long time and there should be no combustible
goods near the amp.
9- If the amp had no security, I wonder if I can order it with some safe guards as B+ fuses, soft start etc??
.. Yes, they can be installed.
As I said above, if you have any questions, please feel free to contact me.
MC3008-A is fantastic. Maybe you can have a try.

I wish say a very special thanks to Mr.Lucasz Fikus and Ms.Suena from Ming-Da factory who kindly take time to send me this very detailed infos.
