bigx5murf Posted October 2, 2017 Report Share Posted October 2, 2017 I found a pair of L710 in somewhat rough shape at goodwill for $15 a week ago. I've been slowly working on them as time permitted. So far, I've... 1-refoamed all 4 woofers, they were completely disintegrated, these were very difficult to align with test tones, took a few tries each, except for one which I got the first try. 2-replaced the 90uF cap on the crossover, this was surprisingly difficult to find. I ended up running a 68uF and 22uF cap in parallel instead. 3-Installed 5 way binding posts. This was difficult to find ones long enough to work. The only ones I found were from PE, required boring out the contacts and PCB on the crossover. They work, and sound great as is, but there's a few cosmetic issues I want to tackle. I'm going to replace the grill cloth, already have the cloth, not sure what glue to use. Can anyone recommend? I want to refinish the cabinets, close to original as possible. The cabinets are in decent shape, but the inner panel on each is much better than the rest. One panel has the damage in the pic on it. What's the easiest way to get a nice even finish on these?

JKent Posted October 3, 2017 Report Share Posted October 3, 2017 Looks like you should be able to sand them lightly and then use some tinted Howard Restore-a-Finish to even it out. Quote Link to comment Share on other sites More sharing options...
bigx5murf Posted October 3, 2017 Author Report Share Posted October 3, 2017 Should I do that to all panels? One panel on each is actually in very good shape, the top, and outer panels are very faded. Quote Link to comment Share on other sites More sharing options...
JKent Posted October 3, 2017 Report Share Posted October 3, 2017 Here's a suggestion: First wipe down all sides with a solvent such as lacquer thinner or mineral spirits. Lightly sand the damaged panels and use the Restor-a-Finish Dark Walnut on the faded and damaged panels. It can be applied with a rag and wiped off. On the other surfaces, if no sanding is needed, use the R-a-F in Neutral. Then compare the sides and if any sides need to be darkened any use the Dark Walnut. When it's thoroughly dry, you could use Watco Oil, or just wax (like Howard Feed n Wax). Don't use any hard finish like lacquer or varnish. Some people like to use the Mahogany Watco oil to give the walnut a warmer, slightly reddish tone. Experiment. Quote Link to comment Share on other sites More sharing options...
GD70 Posted October 14, 2017 Report Share Posted October 14, 2017 You basically stole those for 15 bucks! The L710's are highly regarded. Kents suggestions are good, except it will be difficult to match the original finish if you only work on the one surface. You may get it close and be happy, but if these were mine, no question the original finish would be removed, all surfaces sanded and any veneer repairs made if necessary. By starting clean with all surfaces stripped to the veneer, your final finish will be even. It all depends on how much work you want to put into them. I'd love to see more pics showing the complete cabs, drivers and crossovers. I'm surprised the surrounds needed replacing. Being butyl rubber, they usually hold up very well. My 910's from 1977 surrounds are in great shape. Glenn Quote Link to comment Share on other sites More sharing options...
JKent Posted October 14, 2017 Report Share Posted October 14, 2017 Glenn's method is better. My suggestion is easier. Depends on how much work you want to put into them. I was responding to "What's the easiest way to get a nice even finish on these?" Just be really careful when sanding, especially on the edges and corners. Veneer is thin and goofs can't be undone. -Kent Quote Link to comment Share on other sites More sharing options...

I'm just stupid anal about stuff like that! Cheers, Glenn Quote Link to comment Share on other sites More sharing options...

Been using them ever since, and am still surprised by how good they sound. I actually have mine on 3' stands, which is probably not the recommended way to position them. I've been using these on a system that lets me switch between 4 sets of speakers, they're as followed ADS L710, EPI 100v, Polk SDA-2B, and Sony APM 690. Yes that's the order I prefer them in.

tonyE Posted February 2, 2019 Report Share Posted February 2, 2019 Interesting... my L810s, which I've owned since '78 -brand new, still have the woofer rubber surrounds... and still in great shape (knocking on walnut veneer)..

Steve Kay Posted August 16, 2019 Report Share Posted August 16, 2019 I have a pair of L710IIs that I bought new back in about 1492. I use them daily and they look perfect. I am beginning to hear a little raspiness on some mid-range to high notes, both instrumental and vocal. I could be my amp (a Denon PMA915A from 1997) or the speakers. I am wondering if the capacitors in the crossovers could be the culprits. Any suggestions? Steve Kay Quote Link to comment Share on other sites More sharing options...
