the amplifier is practically a gift and will by which he came.
Nothing to do with a Master Sound Dueventi SE.
If someday I decide valves certainly be a design single ended triode mode and perhaps with the euphonic distortion characteristic of EL34 through neutral speakers. These 20 wats have sounded at 30 meters for a month to a Dynaudio Contour 1.4S at a level simply delicious.
Meanwhile, Densen DM-10, one of the best electronic in absolute terms for "making music" that never met regardless of their quantity. It has air flow and a good balance SET throwing with a touch euphonic without losing face next neutral sound with a nice attack, dynamics and sense of rhythm.
The Ming gives you the hours counted. If you have not already gone out the door is because I want to "investigate".

As I explained you before, the holes for tubes were drilled according to most impressive look, the tubes were selected according to most impressive feel. Thanks to nice transformers I can turn each their amp from a worm to a butterfly, but it will loose possibility to play with tube rolling. Your choice.
Dear Ming-Da developer; I know you read the forum. PM me and we can schedule production of butterflies that will be blamelses (Is this word patented, Doug?)
Could you do it without mosfets/lgbt's/gyrators/thyristors/LED's/current sinks/current sources? 😉

Sure. Tubes can be happy with resistors only. 😀
But to power them I would use properly conditioned sources. 😀
Can get this product for $US998 from catty link. I've used them before. From ordering on Monday, product arrived on Saturday, beautifully packed. Hong Kong to UK. Pretty good.

What for did you use them before?
Edit: I'm afraid we are attacked by advertising robots.
In the Ming-Da site there is a pop window warning against Ebay and CattyLink shop:Can get this product for $US998 from catty link. I've used them before. From ordering on Monday, product arrived on Saturday, beautifully packed. Hong Kong to UK. Pretty good.

I would prefer buy direct from Ming-Da factory with Ms.Suena.
According Lampizator and Pacific Valve the 805 SET is a great amp, which looks true for me.But do MingDa amps actually sound any good?
@wavebourn-I used them to supply an ESound E5 Signature Edition CD. A really well made and superb CD player. Replaced an ageing Marantz CD63 KI SIGNATURE. Very happy with Cattylink.
But do MingDa amps actually sound any good?
Yes, pretty good. But can sound much better with minor changes (well, "minor" may mean throwing out some venerable tubes in favor of unknown ones, depending on the model).
before buying any tube amp, make sure you know where to have it repaired or just serviced
but i guess this is a DIY forum for a reason

Oh, I was thinking about buying a Mingda for its nice enclosure and iron, and modding it with my own circuit. But if it already sounds good, then I'm no longer interested.
you can make almost anything look nice
but honestly, I think they are ugly amps
no doubt its an effort to try and make it look expencive
but to me it just looks cheap fake, and poor style with no class

well, maybe we got different tastes. I like MING DA design, simple but elegant. They are not fancy or showy.you can make almost anything look nice

As for the sound, I could not tell much more. But my friend's MING DA MC34-AB is so fantastic!
Actually, their handcrafted circuitry attracts me most. Now too many solid state amps are polluting the market.
We'll see.

Once more, nothing elegant in them. And nothing simple. Look, driving 845 tubes by 300B tubes that were not needed at all because he used them on currents on which they are very non-linear he had to add isolated filament supplies because 300B tubes have direct powered cathodes. Is it elegant? Is it simple? Are you kidding? Their cirquitry is hand-crafted to fill the holes on the chassis that is hand-crafted to get rows of nice looking tubes, that were selected according to their reputation among buyers. They don't fit into the schematic technically.
Damongbarker, I was too polite replying to you before, but I can't tolerate such dishonest advertising anymore.
Dear moderators, please move finally this thread to the tube forum where everyone can understand what we are talking about. It is a shameless advertising of the product on a DIY forum using false claims.

I repaired one.
It had rated for 400V coupling caps between 300B drivers powered from 450V source and grids of 845 tubes with applied to them bias. This capacitors failed, causing too high current drawn by 845 tubes. Resistors in 1 KV power supply burst in flame, and burnt coming near them wires that went to the power switch. It was a total disaster. I had to cut part of PCB under that resistors because it become conductive after an electric ark with kilovolt around, replace wires going to rhe power switch, and insulate them properly, then install appropriate capacitors instead of that caps that caused the disaster in the first place. Also, I wanted to redo the whole schematic because I found that output transformers were pretty good, and can be used for really nice amps, but did not do that because it would require to rewire too much. And it would leave empty holes from odd tubes. And would look less impressive because tubes that would perform better would look less impressive.
Brother hasan integrated MingDa. Mc34, i think. It sounds wonderful. He replaved most caps and put kt66's in ouput. All upgraded tubes. Really phenominal sound. Pentode/triode switch. Replaced linn active setup.

I can show you how to make a real amp on the same chassis, with the same transformers, but with different schematic. You will be surprised. But as the source for chassis and transformers their amps are too expensive.
I believe you and would love to see the schematic. His amp was only 1.5k, i think. A lot for DIY. But nothing in hifi world, as you well know. Clearly this pllace is a treasure for the willing, but not all are willing. I am slowly replacing his gear with DIY stuff, so i would love to see your suggestion.

I have seen many pictures of made-in-China "high end tube amps" in many Chinese audio magazines and they did look impressive. Do not forget that the amp manufacturers are making a niche consumer products for sale. Look is very important. Unfortunately, a lot of the buyers (in China) are buying these products based on reviews published in "well known" audio magazines by "well known reviewers". These consumers have do not the foggiest idea what a decent amp would sound like.
I would not be surprised that the amp problem you encountered was due to parts run out during manufacturing. The workers do not want to stop the work and just grab something that is "close enough". This is typical for manufacturing in China - speed, the time line has to be met. Quality is secondary.
Do not get me wrong, great products can be made in China. Just do your own QC and QA. Case in point, Prima Luna is a good example. The company claimed the return rate for their amps are < 1% (this is the figure I got from an interview of one of their senior official published a few years back).
