To remove the deep scratches you can use 2000 and 3000 grit wet sanding and then use meguiars compound for polishing.

Thanks

Pretty much the same process (and polishing compound) when cleaning headlights if the UV coating is yellowing or peeling, except that you have to add new UV protection at the end. Good video.

How did you wire the PowerPoint?

Amazing time

Just came across your video and loved every minute of it and I'm now subscribed. Wharfedale didn't make a full range 15" driver but did make both hifi and musical instrument versions of the 15" units. When fitted to 5 cubic ft. and over enclosures, the Super 12's sound sensational but as you say the surrounds would need attention for optimum performance. I've also noticed that all four of your drivers are of the ceramic magnet type. If you think they are good, try the Alnico magnet versions if you can find a pair. The comparison is (to my ears) like chalk and cheese. I'm not sure of the details and dates but I suspect that Rank thought that the ceramic magnets were a cheaper option and probably outsourced them as Gilbert was manufacturing his own Alnico magnets using a DC power line (utilised for electric trolley buses that ran past his factory in Bradford Road). Legend has it that when they threw the switch for the electromagnet, the trolley buses running past would come to an abrupt halt!

Thank you

My girlfriend surprised me with a set of Coral BX85s I had my eyes on for the last few months from an antique store. Had no idea if they worked, I was just taken away by the aesthetics. Needless to say, I was ecstatic to receive these as a gift. Hooked them up into my Pioneer SX316 receiver from mid 00s, and modern turntable. They sound incredible and drive really well. Integrated high frequency adjustments on the back, these things really sing and have a lot of warmth. Super pleased with them.

Saludos, no le veo sentido cambiar el filtro o los imanes de un par a otro, no sé cuál es el fin, hay que preservar la originalidad, salvo en los casos de reparación y aún ahí hay que cuidarlos y preservarlos, todo se debe a caprichos personales o a qué....

Hello! Great video! What size ruby bearing did you order?

The only drawback to the original AR Turntable is the Tonearm if you build a bigger plinth I would of upgraded the Tonearm to

I really enjoyed this video. It makes a change to see someone doing a restoration that anyone could do with basic tools, rather than needing a state-of-the-art woodworking workshop with CNC machines, table saws, milling machines etc.

Thanks for the wonderful video. It is helping me on my journey to restore an early AR XA. I'm going with the jewel bearings and cardas wire. Here in the States the shipping and general costs are much more affordable. I love the background music and the humor too. (Yippy, another thing that can go wrong. :-P ). Great work and hello to down under!

OMG! use a scrap wood or plastic to push the wood.

No riving knife behind the blade, good luck...

router is not a circular saw

Great story but sort of glosses over the impact that Henry Kloss had. Seems like the original idea was indeed Edgar's but Henry did all the work which I believe was why they parted company. Also, Henry felt that a two-way system was easier to "voice" and why the KLH 6 and KLH 17 were such successes which were of course designed after he and Edgar had a parting of the ways and Henry took Lowe and Hoffman to form KLH. Henry unfortunately lost his way after Advent. He didn't see flat screen TV's coming and they blindsided his dreams of video projection as being the future of TV. If only he had stuck to audio.

I correspond with Keven from time to time. He introduced me to tube amps , and open baffles. Two years ago he sent me a pair of Coral Holy Baskets as a Christmas gift. I'm now using them in a open baffle bi-amp setup with pair of digital audio Maraschino Cherry amps driving Two ten inch bass drivers in each baffle, and a 300B tube amp driving the corals. I'm using a Marchand electronic crossover set at 400Hz. I was using a pair of Tang Band W8-1808 drivers and then later a pair of Mark Audio Alpair 12p drivers,. I was reluctant to retrofit the small Corals , because I didn't believe they could compete. Was I wrong ! The Little Corals trounce them both in detail and separation. I have played them as high as 100 db with no distortion. Every time I listen to these 3.5 inch drivers , I'm totally amazed at how great they sound.

Le mie AR M1 sono fantastiche. Il rapporto qualità/prezzo è insuperato e insuperabile. Saluti da Roma.

At last, an easy solution which I can build. Thank you.

You could also use the headlight lens restore kits for cars.

Great history,thank you 😊

This vid makes me want to resurrect my AlNiCo 12" Wharfedale full tange speakers from the '50s. I bought them with disintegrated surrounds. I installed new, foam surrounds as that is what they had on when I bought them, but they were gone. I don't know where to get cloth surrounds. I think one of them had coil rub so that's why I didn't use them much. Thnx for showing how to fix them. I own many 'dales with cloth surround drivers. I never thought that they'd let air through. The rubber cement is a good idea but I wouldn't want to impact transient response by having too much weight from impregnation with glue. How did yours turn out with three passes of rubber cement?

Ciao molto interessante il video purtroppo non capisco quello che dici ma qualcosa si perche il video e fatto molto bene a questo quesito vorrei un consiglio come lucidare il piatto del mio giradischi thorens td316 purtroppo devo usare olio di gomito non avendo nessuna ruota che tu usi essendo molto ossidato molto scuro immaginoche devo iniziare con carta vetrata e poi con con pasta abrasiva per la lucidatura opure cosa mi consigli come fare prima della lucidatura complimenti per il video ti seguo ancora aspetando la tua riposta un saluto alla prossima

Excellent work!

I worked for Dr. Roy Allison back in the '80's. Allison Acoustics was located in Natick, Massachusetts. Great place to work. Our speakers are still being enjoyed.

Great video! Well done!

So the logic is you had to buy this special screw piece because the polishing wheel is so thick and if you had a thin buffing wheel you could just use washers and a nut? Cuse my doubts just want to attach this polishing wheels

Hello What is the part number for the sapphire pivot jewel from the Swiiss Company Thanks Anthony

I have found allot of Vintage AR Audio Speakers for Cheap on EBay and bought heavily for Restoring them back to Their Original Sound and Luster in newer denser heavier cabinets and More Modern crossovers than what was offered back in the day.

I Bought Heavily on these 12 inch Wharfedale and the Linton 2's and Denton 2's as well for My High End Acoustic Builds here in Southern California High Desert Music Scene and Everyone agrees They Blow away My Acoustic Research Builds hands down 🙌 🇺🇸 I also appreciate Vintage British Motorcycles

Interdrivers. Are those frames die cast? In any case, if a pair is duff, remove the magnets, remove the dead coil, and glue on a weight holder to make them into passive radiators.

Aaaaaaaaargh! You've messed with the arm! Classic AR restoration mistake! Sorry dude, massive fail. You cannot do that. 👎

so thats where Linn Sondek got their ideas from ...........

You could try to mount the handlebars vertically (and may be closer to the edges,), cause in a horizontal orientation they cause some associations. )

I'm sorry. It not sounds good.

Thats crap. Use Meguiars Scratch X 2.0 and a cotton cloth or microfiber cloth.

Since the work of folk like Villchur loudspeaker advances had all but ended by 1960. Since then it's mainly been a process of refinement.

Hey Dude I have that minimus 7 as my desktop speakers. Love them. Cant let them go :) By the way what do you think of coral 8tx-70?

Always like Aussie accent.

excellent video

Every time I look over documentaries I get really sad. I grew up in probably the best time of our country. If I had the backing of my parents, I could have been part of all this innovation and development. I had negative and toxic parents. I'm 66 and making one more go of it, life. While all my friends from Highschool, their lives are winding down, I'm cranking it up.

Excellent exhibition of percussive maintenance. I had most of (we'll get to that) an AR-77XB land on my bench a couple of days ago, for some light maitenance and a new power lead (Aust standard). As I was drawing up a diagram of the existing wiring so I could rebuild it into a 4 way screw teminal strip (note to self: must go to #NOT SPONSOREDings and get more), I noticed the 115VAC and 60Hz markings on the Haydon motor?!?! FTW?!?!?! I'm putting a lead on it, so it can be plugged into a 240VAC, 50Hz supply!!! Asked the mate who'd passed the job onto me about it, and he returned soon after with the base plate with the serial number sticker, that matched the number inside the unit and aslo had, "220-240 VOLTS AC 50HZ 1.5 WATTS", printed on it. He also told me, the person who had asked him to look at it, had told him, that it had worked in Australia. Next, he pointed at a random turntable lid on the bench that had been getting in my way for at least a week and said, "That's the lid." (Annnnd we got to it.) I'd already come to the conclusion that the drive pully was most likely compensating for the change in motor RPM. (Largest diameter drive pully I've seen on a belt drive turntable) And was massively relieved to have you confirm that. I'm still a little concerned about the "discprepancy" in supply voltage(s). Having run the numbers, the current drawn is piffling at 115V and half a piffling at 240V (~12mA and ~6mA respectively). So nothing sould be overstressed. You kind of cruised through the actual connecting it to the mains. So I'd be really interested to know what you were feeding it. Thanks for an excellent series. P.S. You might want to convince your wife to get some clear nail polish for you to nick. The red really was pretty jarring. ;-P

ok, not bad at all. Thanks....

Beautiful.

AR forever!! I own a pair of AR38s, still sounding very good. Now I’m searching for a pair of speakers from the 70’s. Such as AR6, AR3 .. Thank you very very very much Edgar Villchur. You and the workers at the AR, changed the listening of music, you made history. Thank you America 🇺🇸.

Do you have any idea what the product is called that manufacturers put on lots of the screws in products alot in the 70s and 80s, it was usually green or red, it was used to stop screws from moving and it was hard and shattered when the screw was undone, sort of like when people use nailpolish to stop a screw from moving, except nailpolish doesn't shatter when the screw is turned, do you know what that product is called?
