A '69 TU-777 to go with my '69 AU-777. Manufactured two months apart. Let's just say that seller underrepresented the condition and functionality. Straightened the switches, changed the bulbs, and a good clean. Fun discovery when I took the nice wood case off - L402 the 39mH/71KHz filter from F-1013 FM Multiplex board was jammed in this tuner string pully/roller and the string was snapped. Explains the free spinning tuner knob. Into the shop it goes. Looks great now though. And yes, I'm holding the filter upside down and I used green LEDs. It is what it is.

My AU-11000 and BA-2000 are back after six weeks away at rehab. Many thanks to @Drugolf for facilitating the introduction and transport to the right guy. Couldn't be happier. Clean, pure, and powerful. Now to figure out some workable configuration and rotation for all this gear! I'm inclined, for the time being, to run the 2000 off the 11000. Sacrilege?! I'm here for your thoughts on that. I also picked up a slick little Sanyo Plus C55 preamp for next to nothing. Connected to the Sanyo and my phone, the 2000 and my B&W 685s almost blew me out of the house last night! Felt like I was actually hearing the B&Ws for the first time in the 14ish years I've had them. I'm very tempted to acquire a CA-3000 to pair with the 2000. Besides the obvious eye candy quotient though, what might I actually gain? My wallet needs a cold plunge! I've a pair of racks coming this week and will start to work towards a (semi)permanent setup and configuration. The 5000A should be back this week with freshly modded F-1040 boards and other tune-ups. Lastly, I acquired a grubby, scratchy, but fully functional 4000 to clean up.

Have a listen: AU-11000 - Tom Petty

It would be interesting to know if you hear any difference between the amps in the 11000 and the 2000. Seems unlikely to me, but I've not had the opportunity to hear them. At one point I compared the boards in the Definition and Professional series. Turns out the CA/BA-2000 is an AU-11000A in separate boxes. The boards are identical. Here's the table I put together. I've color coded the boards that appear in more than one unit.

Super interesting! I'd understood that the 11000 and 2000 were integrated/separate versions of each other, but here you can see it's really the 11000A with the drivers and power supply syncing up. So there is some technical difference between the 11000 and 2000 amps. If I run the 2000 off the 11000 then I can easily A/B between the amps with the Pre-Main switch and the 685s have two sets of binding posts to connect from both amps. Should work, right? The sources will remain consistent coming from the 11000 preamp. As you suggest though, I'd be surprised if I will be able to hear a difference. It'll be a good exercise nonetheless.

I will say this, I was absolutely slack-jawed around 2am this morning listening to the 2000 off the Sanyo and my phone. Real power. I couldn't shut it down to go to bed! The 11000 sounds great right now streaming the WiiM Ultra.

@KeithD I suddenly found myself with a nice pair of Klipsch KG 4.2s last Friday. Since then I've had a sonic epiphany, or two. The 11000 in integrated/connected mode coming off the WiiM Ultra and Spotify is the most superior sound I've ever heard. No question. Anybody who poo poos the 11000 is over my head, or whining. The BA-2000 sounds fine running off the 11000 pre, but it runs HOT enough to fry pork chops and takes a couple hours to cool down to very warm after cutting input! So, it's going back in to my guy to check bias, etc. Thus, too be fair, the comparison is TBD. The 11000 is stellar.

Nice! Glad the 11000 is sounding great. I love my 9900, don't think I'd ever part with it, especially since I have the matching 9900 tuner. Hopefully it's just the bias setting on the 2000 and not something more serious.
 
Another big Sansui day for me and general state of the collection update. BA-2000 and TU-777 are in the shop. Should see them back in a few weeks. AU-X11 deal didn't close. Maybe another time.

5000A is out of the shop with updated driver boards and other upgrades. Returned with a big baggie of old replaced parts. Bit of a **** show this was. All seems to be working well. Probably one and done with that tech. The 5000A gave him fits. First he claimed that the F-1040 kit from AFA was short parts and he had to supplement. I doubt it, but okay, whatever. He didn't have any problems with the left side. Nonetheless, he somehow managed to blow the right outputs. Seems like the whole point of this exercise was intended to avoid exactly that. Anyway, he managed to source an og pair of Toshiba outputs and all is apparently well. Sounds great, everything is working, and all appears in order under the hood. Yes, I checked.

Then, out of the clear blue sky, I found an original owner, untouched, mint 3300 nearby. So, I'd just picked up and paid for the 5000A and was off to the ATM! This guy was a pilot for TWA and he flew MAC (Military Airlift Command) shuttles out of Vietnam. He thought that he'd bought it in Guam, but his wife said it was Okinawa. He didn't argue. This supports the theory that these were military-only units and that's why we don't see as many of them. This 3300 was built in 1972. The only thing he didn't have was the box. He'd finally thrown it away during the last move. It sounds excellent and the functionality and features are simply amazing. I have to get some tape machines. Then, given my enthusiasm I suppose, he says, "take the speakers too." He threw in a rather elegant pair of Canadian stand mount Energy Connoisseur C-2 speakers. I've never really seen anything like them. Not really my style, but they sound great and we'll see where they end up.

Otherwise, it seems I have a little AU-217 en route. Might be a project. I'm not sure. OEM Sansui rack handles arrived today and I'm debating adding a TU-217. Credit to @JimEGR for this one. Somewhere out there he said, "focused perfection" if I'm not mistaken. For someone who thought he'd have nothing to do with tuners in these modern times, I seem to have choked on that one. I mean, it is a vintage hobby right?

Lastly, I think I like the look of the 4000 and the 800 best in this line, and I really want a 7000. I'm also looking at tube phono stages to mix in with my collection. Could be deadly with the 777. Now, some pics.

I mean, come on. The signal meter is pinned on a length of speaker wire. The last time that case was off was when it was put on for the first time 53 years ago. A Sansui tank of the highest order. Every bit as robust as the 11000 or BA-2000. Quite like the 8500 in dimension, build quality tank/form factor, actually.
