Look at DAK.com for a $69.95 Bluetooth Upgrade with analog outs to plug in to your receiver. I assume you're going to receive Spotify and send it out on bluetooth.

A while back, when I used a Sony TA-E1000 ESD AV preamp, which has 2 front outs, I switched between a SS amp and a homemade 45 tube amp using a 4PDT toggle switch on the speaker wires. My goal in the late 80s, when I got started in surround sound, was to build a good audio system with video capability. Two La Scalas, an H1, four H2s, two Khorns, an Academy, and a Belle later, I think I'll probably end up using a 4PDT toggle switch again.

Checking capacitors involves isolating them by unsoldering at least one of the leads before testing. Otherwise, everything else in the circuit is interfering with the results you're getting. Do you have a schematic of the board?

That was referred to as Premature Kojakulation.

I started out by reading books written by Alfred P Morgan (1889-1972). The Boy's First (second, third, etc) Book of Radio And Electronics, and others he wrote in the first half of the last century. It got me interested in soldering things together back when I was 7, still doing it 50 some years later.

To make things easy, connect your negative wires first. Left negative from amp to left speaker, then right negative from amp to right speaker. Then it shouldn't matter where you physically locate the fuses, either close to the amp or close to the speaker. Connect each fuse in the positive wire between the amp and the speakers, like a wire from the amp to one side of the fuse, then other side of the fuse goes to the positive on the speaker. If they're small glass fuses about as big around as a pencil, inline fuse holders are available that already have a few inches of wire sticking out each end of the fuse holder. That keeps soldering to a minimum, unless you enjoy soldering.

Another thing I don’t understand is why the ad mentions several tube types that have nothing in common besides being popular?
It's to take advantage of fLeaBay's search feature. Try typing in RARE and see how much stuff pops up.

Welcome to the forum. My question is generic, since I don't have a Three. Does it feel like the knob is loose on the shaft?

When we move to the Philippines, we will probably downsize everything...
I was stationed there in the '80s for over 6yrs, have land there already, going back in a few more yrs. Look into the SRRV visa, if you haven't already. Something like $7k tax free for bringing in stuff.

I was also on a device that would not allow me to “follow” the thread.
Try a screen shot, then use the picture to come back to it later.

Does anyone work on speaker boxes in NYC? These are HUGE and I am not handy. So there's that, too ; )
There was (is?) a show on TV called Million Dollar Contractor where the proprietor has a shop in Brooklyn where they build cabinets that they install in their customer's homes in Manhattan. A Google search should turn up the name contractor's name.

Does rebuilding the power supply include replacing the 5 caps and testing the 5 resistors, replacing anything out of tolerance?
-
Watching it was cringe worthy. The repair is functional, but far from cosmetic. I dig out the guts of the old caps when possible, and restuff them with new parts. YMMV

Thanks for this, @babadono. For many of us in the SF Bay Area, Joe Minor was a beloved resource. In his little "hole in the wall" store in Berkeley, and his engineering room next door, we spent many happy hours listening to Klipschorns, JBLs, 1 Bozak, etc. The Khorns were the best of the bunch. I believe he was the first Klipsch dealer in the Bay Area, and people would drive long distances to hear his demos. He loaned us equipment, and helped us design custom rooms, and expounded on myriad topics, audio and not. He attracted young engineers who graduated from his store and went on to help develop the field. One was John Curl (later famed Parasound design engineer). Another was Don Helmholts, who went on to co-found Pro Audio in Oakland, another wellspring, and who built me a little mixer when I couldn't afford a board. I'm glad Joe introduced Arthur Fiedler to Klipschorns, as well.
Thanks, Gary. In 1991 when I lived in San Diego, I answered an ad for a pair of Khorns. A little old lady on her way to a nursing home was selling her pair of KCWRs. Fortunately for me, her portable CD player connected to an Onkyo receiver had a noisy connection, which the first guy to audition the Khorns perceived as a bad driver. He passed, and I got them. She gave me a package containing a receipt from Berkeley Custom Electronics, dated 2/3/67, signed by JMinor. I appreciate hearing the backstory of the shop where my Khorns were purchased some 53 years ago.

Now we have a older satellite receiver, I thought about calling for newer model but were not in contract anymore so we would have to sign up again. I guess I need to see if they have better receivers, kind of hope not, staying out of contract makes it free to quit if we decide on some other service. I know it will not be cable, here it cost more than satellite.
The crazy part is new people signing up for satellite service even after the lower trial period get's a better price than we do and we have been with them for many years. Thought about canceling and signing up with my wife's name.
The new Direct receiver can't transfer the recordings off the old receiver, so you'll lose whatever programs you had saved on it. I moved last year and left the old antenna on the old house and brought the receivers I had. The new antenna is much less forgiving of weather. Before I could get reception if I got the accumulated snow off the dish with a broom, now the new one cuts out every time it rains. So something new=less use.

Ok guys this is what I have learned, the 6J5 GT tube is exactly one half of the 6SN7. So you will need adapters that go from two 6J5 GT's to one 6SN7 tube. The adapters can be found on ebay for around $50 for a pair. These tubes are the most linear octal tube out there period, if you know anything about tubes the more linear the better the sound quality. I have been using these tubes for about two months now prior to that I was using the 6F8G tubes which are identical to the 6SN7 but have a different pinout so an adapter is needed.
Adapters???? How about hole saw, drill press, soldering iron..... we don't need no steenkin' adapters? Seriously, having to go thru a stack of tubes to find one that works or isn't temperamental doesn't sound very appealing. Many if not most of the published schematics for 45, 2A3, 300B, and other amps use the 6SN7.
-
My Glass Audio 45 tube amp used a 6SN7, but I cannibalized the chassis to build the Little Sweetie monos which each use a 6SJ7. I'm just dying to know what the huge improvement in sound quality might be. Could you possibly let us in on the secret???

You measured the coil's resistance and it is 250 ohms. If it were open, it would be bad. 250 ohms is likely good, as all coils are different based on the amount and gauge of wire in them. Look at the fridge's print to see if it shows the resistance of the coil. But as it stands, R=250 ohms, V= the voltage that operates it, and you can calculate the "I" value, current, from there.

Those turrets at the end of the binding posts are for soldering wires onto, makes one less mechanical connection to have problems with later on. Very nice work on those Belles, keep going, you're almost there now.

That area is as dry as a frog in a sandbox, but those crossovers look abnormally rusted.
