So would it be good, bad or indifferent to twist the wires together that go to the tops of the main tubes? Similar to the pic shown a few pages back.Thinking about as is, could act like an antenna?

Left is the old one. Right is the new one, 6n2p ES, extended life.

Dont mess with these wires, these wires are too short, antenna effect dont happen under 1M long.

Huh, you sure the left tube is the "old" tube?  Is your second photo of the tube box of the tube on the left or right?
Because the tube on the left (and the tube box) seems to be the Russian 6N2P-EB(EV, not ES) and the tube on right looks like the Chinese 6N2, which you can tell by the star and Chinese letters around it, which is the stock Chinese 6N2 tube that came with both of my FU19/FM30 amps.

This box are from a Russian 6H2n-EB tube made by Voskhod.

OK, thanks.
For now I have settled with using Mogami 2549 for the SE and balanced signal cables, and Supra CLassic 1.6 (15 AWG) for speaker cables. Both would qualify for C&C (cheap and cheerful) cables. This setup now is sounding wonderful, very happy with it.

IMO the Supra awg 15 are too thin, try use the Supra awg 15 x 2.

Is it true even with the so low power of the amp?

Yes if used as speaker cable IMO.
But in the end its all about personal taste.

Yeah I've been bouncing back and forth between the Supra wire, and Mogami 2921, which is a 14/4 cable. I feel there is a difference between the two. When I add the Heil tweeters to the speakers, plan on switching the Supra over to those. The article below is a bi-wiring receipe, but I just bundle the red/yellow and brown/orange for a higher gauge 2 conductor.

Just for information/reference: The two Chinese characters 北京 （Beijing). Presumeably, this tube is manufactured in or near Beijing, China.

Good to know you can read Mandarim

I switched out the long body for the wide body amp. For some reason I originally thought the wide body may had been a lesser quality unit (due to the cheaper price). It's not, actually I prefer it. I like the toggle on/off switch vs the push button on the long body, just seems safer. Also the 4 ohm speaker terminals, in case I want to try it on my Heil AMTs later. The volume control on the wide body has detent setting, which some may like. I run mine full on so no matter. Using RCA 829b and the stock Chinese 6N2 tubes for best sound so far.

Also another neat discovery. Due to moving the boxes around, the W4S M-Pre preamp ended up being too far away from the amp to use the same Mogami 2546 with Furutech FP-126(G) cables, so had to grab the cable bucket to find something a little longer. First try was the BJC LC-1s, which I use in the HT system (and lots of it!). But not a good fit here, although I do use it elsewhere on the plate amps for the lows.

Then grabbed some of the Belden 8402 with Switchcraft rcas, which were all the rage a few years ago. I originally had wired them the Yazaki style, with the shield connected on both ends. They sounded like they did last time I tried them, a little harsh on the highs.

I recently had read on the Cheaptubeaudio blog on how he preferred these types of Belden cables wired with one end with a floating shield, the same way I have my Mogamis configured. So did a quick surgery to give it another go. Much better, in some ways superior to the Mogamis. So the next step is to rebuild them with some extra Furutech FP-126(G) rcas I have on hand. From what I understand, Take Five Audio used to sell this combination at one time.

I like the Belden 8402 strengths, which will synergize great in many system 'milieu.'  However, IME Single-ended tube amps can usually withstand the quirks of pure silver wire while benefitting from the synergy, so if you plan to use those Furutech FP126 connectors to build another cable, you might as well investigate the Xangsane SP-9001Ag wire, which is unbelievable value for the transparency. 

One can also make XLR cables out of SP-9001Ag.

Very nice. What kind of XLR connectors are those?... Never mind, I found your post over at AA.

These clones do look nice and sound good, but I would now just buy some standard Neutrik XLR connectors or similar.  I find that many Chi-Fi equipment comes stock with certain types of chassis XLR connectors, which sometimes don't connect/disconnect as easily with certain clone connectors.
