I only have this SMSL SP200 amp, its nice but the neutral sound gets kind of dull after a while.
Miss the P20 and I'm dieing to try these Russian tubes.

I don't believe there are any capacitors between the op-amps and the output jacks.
.
I expect there are DC blocking capacitors at the input jacks.
.
And there are probably capacitors in series with (and isolating) the audio signals in the high-voltage tube section.

Glad to have such a technical mind with strong electronics knowledge in this thread but I wish I could understand the things you say.
Got my amp back from Keith today.
Its a significant improvement. The SMSL SP200 is my standard for comparison since I've had it for quite a long time. I only have the two amps and I always would analyze back and forth with the SMSL SP200 and without a doubt especially the higher frequencies, SP200 was always more capable with clarity, detail, resolution, punch. The P20 is a hybrid amp so I wouldn't expect it to match a solid state THX amp in those aspects but its definitely getting closer with the upgraded caps. Its improved the most in the higher frequencies, thats where I felt the stock P20 fell behind the SP200, its now narrowed that gap a good bit. Also, its seems warmer and tubier now.
Man the way the female vocals ooze
Need more time to determine differences in detail for sure but I know I like it better, its definitely more enjoyable to listen to than my SP200.
Now I gotta try these Russian tubes

These were the tubes that I landed on, haven't tried them yet though, will come back here as soon as I'm done comparing them to the stock ones.
So these arrive today from Romania
Califmike33 another ebay option for you https://www.ebay.com/itm/6N3P-TUBE-...768720?hash=item48ebec2b90:g:MxkAAOSwXmFeybcQ
Yes, they took a good 3-4 weeks to arrive, but having a tested matched pair for that price seems very reasonable. You're still in a bit of a lottery if you just date or batch match tubes.
Sound wise - obviously these two are just getting comfortable and I'll know for sure when they are fully settled in - the upgrade is similar on just the unbalanced output as the comparison to the balanced output with the stock tubes. Getting a fuller, rounder sound altogether with the impression that everything just has a little more weight behind it. Not necessarilly a warmer or more 'tube' like sound, just more heft. Today I'm listening with DT990 pro250 ohm but later I will try my HD660S on the balanced output.

Recently received some of the GE 5670w tubes from ebay. I think I prefer these over the Russian tubes.
If anyone is interested it looks like the US government recently released some NOS and there are quite a few sellers on ebay selling a pair for under $20.

I cannot seem to be able to connect any power adaptor to the P20 other than that it came with. I have several power adapters around with the same plug size but they just refuse to enter, as if they were too large. On the other hand, the loxjie's just plugs to any other socket.
Someone else had this problem?
