Russian Tube Preamp, No Return, Here I go again


I decided to risk it, Russian, no return. (he accepted my $400. offer, so $500. delivered).

Gives me tubes in my office system.

I just read something:

People don’t want advice, just confirmation

I’m not looking for either (this time), just thought some of you would find it funny and wish me luck.

I’m 72, it may arrive before my 75th birthday

just for fun while waiting I'm still peeking at tube phono preamps, 

this Muzixshare integrated amp looks a lot like my Cayin: construction/quality/features/25w triode/45w ultralinear power rating ...

AND it has built-in phono and headphone amp, meters, external bias control

$1,600. delivered to USA

If I didn't have/love my mx110z's phono, and IF it had 16 ohm taps and IF it sounds like my Cayin, I would try it, perhaps then sell the Cayin.

I think you missed my point, I don't like ANY of those currently available preamps, none too special, most ugly IMO (don't forget, I'm an Interior Designer), thus I could not have gotten the 'same' domestic product.

Once again, like the Russian tonearm, this one turned out to be the only currently available one that appealed to me, the one I couldn't forget about while searching for others. Not awesome looking, it just appeals to me.

Both my Fisher 500C's sound great, but, aside from extra height they are very deep, even deeper with input cables, they won't fit here.

This preamp will fit on the 14" deep bookcase top even with cables connected. If I make a cutout in the back of the bookcase for ventilation and cables, I can fit it on a 11-1/2" deep shelf.

It's always a mixture of considerations that lead to a decision.

If Aristophanes said it,i never correct Einstein after all.... Only gloss around him...

Humility must be my mentor now..... 😁😊

I will not try to correct E=Mc 2

Rest assured....
two small potential issues:

Watch out for the gluing of the red board supports, watch for it breaking free. They appear to be glued to the bottom plate, which will flex. They may also be screwed from the bottom, difficult to know without seeing it.

next potential danger, the red colored supports themselves.

They appear to be 3d printed. the orientation of the print process means that the supports might break easily when presented with lateral shear accelerations. It’s a basic problem with all fusing and filament type 3d printing. Adhesion of the new layer.. to the one below is a problem (In the printing process itself).

In essence, do NOT plug this unit in when it arrives, without taking the cover off and doing a very close inspection, before trying to power it up.

Not saying it will fail, but it is being shipped from ’faraway land’, and there will be plenty of chances for sharp impacts upon the shipping container, and thus some fairly decent sharp shear inducing acceleration(s).

Edit: downloading the image of the internals.. seems to possibly..er..indicate.. that maybe the builder made printed molds for the support and then poured the supports as ’cast’ items, which would probably make them considerably safer for use in high voltage tube based gear. I say this as it seems to be quite difficult to see any 'layers' in what looks a lot like a 3d print job for those supports. using a printed mold to make cast parts tends to make the print layers a hair more difficult to see as a surface detail thing.
