CSUNRocks Posted November 4, 2018 Report Share Posted November 4, 2018 I had to talk to him about shipping and he’s fine with it. And then the price change was because of my situation with shipping. I’m powering them and the other speakers with a rebuilt Yamaha Set of amps. CX & MX 800u. Enough power tom Quote Link to comment Share on other sites More sharing options...
CSUNRocks Posted November 5, 2018 Report Share Posted November 5, 2018 Serial numbers C25803 and C25840. Later in the AR-3 years is my guess. 37 units different. Hugh.... My JBL are consecutive in order. Quote Link to comment Share on other sites More sharing options...

Yes, the cabs have seen better days, but it's mostly scratches with little lost veneer. I will have to ponder whether I want to try lift the scratches or just sand them and love the patina. I might try the iron method on the bottom of one to check out the results. The steel strap covered the pot switches with little pieces of foam wedged between them. I think he just wanted the pots to stay where he liked the settings. He is an interesting fellow--I am not going to wonder his motives beyond that. LC, I'll PM you when I am nearing the grills. I'll try gluing them. If that doesn't work, I'll take Kent's advice on the MDF. Tom, I will definitely test the drivers before I try to take them out. I would rather not have to remove them. Peter Here is the new grill material on a pair of 3's I just refinished. They were just about as bad as yours and original grill material was shot.

My JBL are consecutive in order. Those serial numbers actually indicate earlier production specimens. Over 70, 000 were manufactured. Your JBL's are from a later era. AR-3's were not sold as pairs, and it is very unusual to find a pair with consecutive numbers. Mono amps were common in the early 60's, and "stereo" was in its infancy. A difference of 37 is really quite close for a pair of 3's, and indicate they were most likely purchased together. Roy Quote Link to comment Share on other sites More sharing options...

Lucky Pierre Posted November 5, 2018 Author Report Share Posted November 5, 2018 I will start on the caps and pots as soon as I have the parts. I think the cabinet might have to wait until after Christmas. I put a Festool 5" random orbit sander on my list ? Quote Link to comment Share on other sites More sharing options...

The grille material is available from a seller in Canada. I'll try to find the info if you need it. I would advise against removing the tweets and mids until you have determined they are definitely bad. You can run a signal to each using the rivets where they are front wired. The less those fragile tinsel leads are disturbed the better. -Kent QComponents is the Canadian seller. https://qcomponents.ca/ Glenn Quote Link to comment Share on other sites More sharing options...

Because I usually have it around here, I use 1/4" plywood. Quote Link to comment Share on other sites More sharing options...
Lucky Pierre Posted November 24, 2018 Author Report Share Posted November 24, 2018 I just finished my AR-5s, except for the grills. Now it is on to the 3s. I hope to have the caps replaced and pots cleaned in the next two weeks. The cabinet restoration won't start until after Christmas. In the meantime I am looking for someone local that is set up to spray lacquer. I'll post pics of my progress. Peter Quote Link to comment Share on other sites More sharing options...

I'm in Framingham and I have a sprayer and compressor but haven't sprayed lacquer in years. I don't have a proper set up and it can be dangerous indoors w/o ventilation. The fumes are deadly and highly flammable. Have you looked at using Deft? It can be brushed on. Even with Deft you need a mask and good ventilation.

Lucky Pierre Posted November 24, 2018 Author Report Share Posted November 24, 2018 Hi David. This is exactly why I want to find someone that is set up already for lacquer. I have a friend around the corner that is pretty good with lacquer, but he doesn't have a spray booth. I would have to wait until spring to spray outdoors.

DavidR Posted November 24, 2018 Report Share Posted November 24, 2018 Look into someone who does either bodywork painting or furniture restoration. There's a guy in Natick (Furniture Smith) and another in Holliston (Kevin Bianchi) who do furniture resto. Quote Link to comment Share on other sites More sharing options...

Furniture guys can, though. I found out tonight at dinner that my brother has a spray booth in his new shop. Looks like I'll have to learn how to spray lacquer!

If you're in a must use Lacquer on these frame of mind, Lacquer is very easy to work with, but must be done out in an open garage. I re-veneered the JVC M-7050 & P-L10 pre amp cabs you saw at Frankenfest. I first brushed on around 20 coats of Lacquer to fill the grain, then block wet sanded them smooth. Then used rattle can spray Lacquer for the finish. Sprayed maybe 8-10 coats. It was a lot of work but worth it. With the 3 cabs, I would strongly suggest going with a Danish oil. It's far easier, needing at most 5 hand wiped applications before the veneer will not absorb any more. Sand with 600 grit after 24 hours for each application. You will get a finish like Lakecats.

Lucky Pierre Posted December 21, 2018 Author Report Share Posted December 21, 2018 Thanks Glenn. I think I might go that route. I was being a stickler on putting on an original finish, but I might go with what is easier. I have no doubt that they will be beautiful either way.

Peter I have seen a number of late AR-3 cabinets with an oil finish, so it can still be considered an "original finish". :) Roy Quote Link to comment Share on other sites More sharing options...

Lucky Pierre Posted December 21, 2018 Author Report Share Posted December 21, 2018 Caps are ordered. I hope to have these up and running by the new year. Considering the rock wool, I am a little afraid of what the condition of the pots will be. Quote Link to comment Share on other sites More sharing options...
Lucky Pierre Posted December 21, 2018 Author Report Share Posted December 21, 2018 Well, not as bad as I feared. I think one of the wipers has a hole in it, though. Into salt and vinegar they go! Peter Quote Link to comment Share on other sites More sharing options...
