That was a great and a fine thing to do Jeff! Cheers to all!

Couldn't agree more! Roy has assisted me on many restoration projects, from advice, crossover wiring diagrams, to sending me parts to repairing woofers, and rebuilding the mids for my 3's. One of the nicest gents you'll ever meet. Glenn

Once you have the pots removed and opened up, post pics. Then clean them up and post pics. The contact disks and pot wipers condition will determine if they are salvageable or need replacing. Closely inspect the disk surfaces for pits and missing material, very common from the corrosion. The wipers often have holes from sera of the spinning frictions against the coils. Sometimes this is repairable with a blob of solder if the hole is small. If most of the tip is gone, a replacement is necessary. As an alternative, there's a gent selling new replacement pots on eBay for 30 bucks each. They look great and a few have installed them with great results. The 3a's tweeters are the weak spot. If their output is low once the pots are back in place, Chris can rebuild them to sounding new again. He did a set for me on a set I restored and they sounded great. Regarding the woofers, check the Masonite rings the surrounds are glued to, and the spiders are glued to, make sure they are not loosing from the basket. Glenn

Hi Peter, My mids output was not great, somewhat muted. The issue is the white original flexible sealer around the domes bases had hardened greatly diminishing the domes movement to non existent. Roy removes it, adds some type of silicone dabs to support the dome, which allows the movement it should have. Trust me, you think they sound good now, rebuild the mids and you'll be astonished like I was! Glenn

Chris stated earlier it's his recipe, and cannot tell!

If they really bug you, you can send them to Richard So for restoration. Richard use to work at ADS and bought up all the parts inventory when they closed the doors. His work is top quality, uses all factory correct parts and they will be new and last another 30 years. Nice speakers, but I have to say, once you're bitten by the ADS bug, you'll be looking for more, especially the larger models space allowing. Glenn

Hi Peter, Please post pics as you progress. The 3's are really special speakers. You'll do a great job on them and rewarded for years to come. Consider sending the mids to Roy for rebuilding. He did a set of mine, and the improvement was astonishing, like new sound. Glenn

Parts are readily available, either on fleabay, or Richard So. Richard repairs or rebuilds virtually every driver and crossover. He use to work at ADS, and bought up all their parts inventory when they were closing their doors. I sent Richard my mids and tweeters from my 910's for rebuilding, and they are basically brand new drivers, good for another 30 plus years. Theres plenty of testimonials regarding Richards top quality work, so you have no worries buying any ADS speaker. Glenn

Hey David! Those came out great! The bypass cap discussion is interesting and something I had not seen before.I have no plans to go back into mine, but may fool around with the idea down the road. Glenn

Hi Robert, I brought the 12's as a last minute decision, one because they are seldom heard, and two, easier to transport than the Angelica's, which I was originally going to bring. I also had a feeling you would be attending and wanted you to hear them. It was good to see you again. Glenn

Great, and interesting info as always gents!

Hey all! I want to let you all know about this AK gathering. Kent, who attended the last event, and several others had suggested I post this here as well so more of us audio heads on CSP would be aware of the gathering. Letting you know about it now gives plenty of time to put the dates on your calendars. These two dates will be the 3rd and 4th gatherings at the lodge. There's plenty of space for sales and demo setups. The location is pretty easy to get to, the building and surrounding Blue Mountain reservation park land is beautiful. For the first time at the last event, we extended the rental so we could have a dance party that evening. We had a great time with about 22 or so. There is a kitchen with a large fridge, so no problem to keep your beveredge of choice cold, and of course, feel free to bring food and snacks if you like. Admission is 20.00, and this covers the rental cost for the day and ordering in pizzas. If you, decide to stay and dance the night away, that's an additional 10.00 to cover the extended night rental fee that I've already paid to secure the dates. There is a parking fee, for the day because it's a state park. I'll start a for sale thread about 6 weeks prior to the event. Cheers and hope to see you then. Glenn

Glad to hear you're liking them Peter! Cheers, Glenn

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. Glenn

Oh man, gorgeous! Love the veneer on those. Just had to add an additional comment! Cheers, Glenn

Fabulous! Great examples! My one frame on my 2nd set of 3's was bent and cracked. I had to make new frames from 1/4 MDF. Glenn G

Gorgeous veneer and rebound! Now they are keepers!

Hey Steve! You did a great job on these and, really, after all the work you put into them, you plan to flip them? They sound great, and are a long term investment. Personally, I'd keep these for a very long time, which is what I plan to do with mine. Cheers, Glenn

They will get better as the surrounds loosen up a bit. Good to hear you're liking them so much! I've thought the same thing regarding persuing the 11's and 10pi's, but I'm being really good and not getting any more speakers for now. Great to see another one year wonder singing again! Glenn

The originals are specific to the 12 as well as the mids.

Hi Roy! Excellent news you'll be attending. And again, thanks for your help on the 3's. Reading all the bad news of late regarding the mids, I'm feeling pretty lucky you were able to get the one working that I attempted to repair. Glenn

I had been trying to get Roy to attend a Frankenfest for several years,. It the timing didn't work out for Roy. I couldn't agree with you more regarding Roys generosity. Glenn

Thanks ra ra! It was great to see you again and finally meet Roy. Glad you both got to hear the 3's. I'm going to try to convince Roy, to come to the Peekskill Blue Mountain AK gathering on September 15th. Glenn

A short update. These continue to sound phenominal. Roys mids have held up well, sounding just as they did when first reinstalled. I brought them to the last Frankenfest, and finally got to meet Roy in person, and he got to hear these 3's.
