Yes, these are real sweetheart little receivers. The 7070 has the same amp board and preamp the 9090DB does. Sounds exactly the same with less power. GLWS

What was supposed to be a full recap, was only 2 capacitors replaced in the amplifier. Not cool. Best Carl!!

Around $5K sounds about right. Maybe up to $7K for the guy looking for that pristine one owner.

The 7318 are just as quiet as a Tele for sure. One of their strength's. The Tele is clean and neutral where the 7318 has a touch of tone in comparison in all applications I have tried them in. Now, for vintage tube gear, there is no replacement for Tele's. Some gear just needs them. If using more modern and more resolute gear, the 7318 will win every time IMO. The 7318 is a very damn good 12AU7.

I think this is the nicest FS ad you have ever made! Nicely done, and GLWS....

Any old tube that lights up is worth $10!!

I say that because I don't recall WE making an 805. Just because it says WE on the box don't necessarily mean there is a WE tube in it. That company had their toes in allot of stuff back then, so there is really no telling. It could be though, so I don't know.
I'm sure it is an 805 tube, but I think it is from another manufacturer. Maybe they outsourced them for some piece of equipment they were using, and stuck them in their box. It says Spare on the box as well, which may affirm my theory somewhat.
Even though, a NOS 805 tube from any manufacturer is worth at least $150....

I am wondering if it is an actual WE tube, or an 805 from another manufacturer that they may have used for something.
Hold out though, maybe someone here knows. I wouldn't open it without taking a video of you doing so, noting the date.

Right! What ya got to loose?

This is the best one..... http://www.machinadynamica.com/machina60.htm

Yes, get rid of Tantalums if you can, and you absolutely can here. Replace them with electrolytic caps.
-
2SC945 is a good part, so no worries there, and these may not have 2SC458's in them. I can't remember everything, but if you don't see them, you should be good with just a recap.

I figured about 25 bucks to re-cap the receiver. I'm pondering over it...
The receiver sounds good for a ten dollar 42 year old unit. But after some listening I can hear the weedy, gritty, sour sound of old electrolytic capacitors. It's mostly emphasized in the treble.
These early Kenwood receivers are loaded with noisy by reputation, transistors as well. Look out for 2SC458's mainly. They should all be replaced with low noise modern equivalents.

Let me see what I can find.... Most my tubes are in pairs though, and would hate to split anything up, but I am sure I have some singles for you to play with.
For preamp though, try the RCA COMMAND 5814, Sylvania 6189 with triple mica grey plates, or if you get really lucky, and you want to be done, the Long Plate Valvo ECC82's are about the best 12AU7 there is IMO. Another great tube is the RadioTechnique Short Wing Plate 12AU7 as well as the CBS 7318.
I have heard a couple preamps with a very similar layout as the one you are using, and a combination of tubes will likely be your best result, as in there will be a clear choice for the output tube, and a clear choice for the input tube, once you find them
I would try the RT Wing Plate or the CBS 7318 at the output, and any of the other above mentioned for the input tube. I can help you out with these, but I can't split up pairs....
What model preamp?

What you putting the tube in?

There are a few vintage 2 channel receivers from Kenwood and Sansui, that actually series wire the pair of speakers per channel when running 2 sets. That turns your 8 ohm speakers into 16 ohm. They did this for safety reasons so you couldn't hurt the amp by overloading it with more speakers. So yes, this will divide the power using A+B with these particular receivers.
Reason being is, if you hook up a set of 4 ohm speakers, then want to add another set of 4 ohm speakers, if A+B mode parallels the pairs, your receiver would see 2 ohms, which is a no no for most any receiver, and will most likely burn up the amp.
They did this so the unknowing consumer could hook up any combination of speakers and not hurt the amp.

When I align a cartridge, I use a protractor. VTA I adjust by eye swinging the tonearm as far towards the spindle as I can, and level the cartridge/headshell with the record. Then I play music, and set the anti-skate so that my center image is in the center. That gets you close for the most part. I then adjust by ear.
When one channel sounds a bit more detailed than the other, I rotate the cartridge very slightly one way or the other until it is equal.
If the soundstage is a bit short, raise the tonearm slightly.
Azimuth is easy to tell if it is wrong. Just adjust for the best image focus. If it is too far off, you will have phasing errors and it will mess with your head a bit obscuring the musical picture.
Once you have it, tighten everything up, headshell, screws, etc... Enjoy! You will know when it is right, as everything just works and sounds great.
Key is slight adjustments, and knowing what those adjustments do when you are close. Become the needle grasshopper!

Bumpin with a great Cart!!

All the Kenwood gear is very good. The older integrateds like the KA-6000 and KA-7002 are VERY good sounding.

Hello,
Price: $315 shipped CONUS!! Comes with the Cartridge of course, box, Styli guard, hardware.
Up for sale I have a like new, about 10hrs tops, HANA EH Cartridge. This is the Elliptical Stylus, and is HOMC. Works for most any MM Phono Preamp and works very lovely. Never abused, used on my original VPI Scout.
Selling to upgrade to the SH HANA, so absolutely keeping it in the family. I was just so impressed with the sound of this cartridge, I have to see what the SH will do on my table. It will be less forgiving, but I have the rest of my vinyl rig set up for maximum resolution, so I gotta have it.
This cart runs circles around the Ortofon Black to my ears. It is that good. Dead quiet background, smooth, dynamic, very transparent, and just so very emotional sounding. I don't know of anybody who does not love their HANA! Just check out the reviews for it.
Thank you!!

Looks like these are sold. Thanks very much Tim!!
-
I do like that Pioneer SX-3900!!

$110 shipped!!!

I am quite literally doing some work on one of these right now. Very sweet sounding receiver, and this price is a no brainer.

Don't forget Kenwood! One of the best sounding amps on this planet is a KA-7100.... When I used to sell speakers, my KA-7100 sold a TON of them. Everything I hooked up to it sounded fantastic.
