Russian Tube Preamp, No Return, Here I go again

High Gm tubes like 5687 and 6922 types are “goofball”?

Uh, for the money, It looks well worth the gamble. Nice find.

I concur with the earlier post about there being no such thing as “no returns” on eBay no matter what the seller’s policy says. eBay is very buyer focused with potections. The say that they have Seller Protection. But that is a load of cr@p. If you change you mind on this Russian amp, take a look at any number of quality tube amps made in China. I just bought a 300B tube Chinese amp on Amazon. Got it with Prime shipping in 2-3 days. I couldn’t be happier. Plus if I didn’t like they would likely have me drop it off at my local Kohl’s. Oh, and that amp with tax cost me $800. 

I bought a Conrad Johnson tube amp from a guy in central Russia. Took it 1 week to make it west to the Norwegian border. It took 3 more weeks to make it to my doorstep. The guy did an expert job packing it. Not even the separately packed tubes had a scratch on them. $475.

So, there’s hope! 

Reading the information in the Link, the Pre appears to be a Clone based around a Kondo Design.

Whether the Kondo and this Design Purchased are anything like each other in SQ might not be discovered.

The Info on the Phonostage is quite limited, so that if used will have to be a suck it and see affair.

As for Retro Japanese, the designs usually lean towards a richness in a presentation.
If not controlled it can have a Weighty Bass to Overwhelming Bass Bloom, either of these present, can produce a Subdued Mid and High.

Looking at the 6N23P EV these types are known to not over emphasize the Frequencies when assessing for SQ.
The user reports are that these Tubes are usually performing as very well balanced throughout the frequencies.

Maybe (an assumption)  the Pre's Builder has chose to use Tubes that are going to be a little more lean and balanced in their presentation,
resulting in offering  a tighter Bass Note that will be a little more transparent. 
I'm sure the reports on usage will reveal the SQ of the Pre'.

If Tube Rolling is off interest, the 6N23P and 6N23P EV are a little different and are not direct swaps.
I discovered this as I was looking to extend a Tube Roll on a Phonostage to 6N23P Tubes vs 6922 and E88CC.
