  1. Forget about stacked Advents. Your stack rocks!
  2. Are you serious? For phony Advents? Where do you live? It seems to me a lot of people are getting rid of speakers that are "too big." I recently got some very nice Snells for free. And a CSP member has some AR-9s listed in the FS section for $800 which sounds to me like a steal if you have room for them and happen to live in New England so you can pick them up. But to your point: I doubt that I know any more about xo's than you do but it seems to me that, since your Polks are ported, you could simply splice into the tweeter wires, run long wires out through the port and attach L-Pads, then adjust them from your listening position until you find the setting that sounds right. Then solder in your fixed resistors. Kent PS: Looks like you posted while I was typing but I still think my suggestion would work if you want a reversible fix
  3. Nice work. Enjoy the music. I remember commenting to my audio technician friend that it was my impression that all Canadian hi-fi was excellent. He said "well, not ALL...." He named a company but I've forgotten the name. Electro-something? He said it was an attempt by the gov't to re-train lumberjacks to build audio equipment. Apparently not high quality. Sounds like a Monty Python bit to me 😄 I've always lusted after Bryston gear but never took the plunge.
  4. Yeah, those 47s are definitely new. And 47 is close enough to 50. You'll notice in my re-do, some caps and some resistors are close but not exact values. Speaking of which, it may be too late now but I always recommended replacing all of the 5w resistors with 10w. RoyC looked into this and identified just 1 or 2 that had to be replaced. I have to search my notes. One is the 5 ohm in the upper left corner in my pic. I'll try to get more info. Kent PS: OK. I think Roy said that 5 Ohm resistor in the woofer circuit should be 15 0r even 20 watts. There's a 15 Ohm in the mid circuit. I think it's the one in the middle of the board. That one's OK but could be bumped up to 10w. The other 5w resistors are fine. PPS: OOOPS. We were typing at the same time.
  5. Yeah. Beer softens me up too 😄 Your 4x's have a mesh cap, essentially. That should clean it up nicely but if the wood is thirsty, Howard recommends following up with their Feed n Wax. I use Aleene's on paper cones. Don't know how it will be on poly. I use that nasty nitrile based glue for plastic cones. Looking forward to more posts. Not familiar with that brand but those seem very nice. I think in general Canadian speakers are quite good. I'm told the Canadian government helps speaker manufacturers with R&D. I'd say they were a great find and a good project. Kent
  6. That's right. Is that your only double cap? Sometimes KLH used a double cap but both red leads went to the same point, so a single cap can be used instead. Kent
  7. Welcome back "cousin" 😉 What a great find! (and great spouse!). Not sure about the dust cap. How does the woofer do with a push test? If it springs back maybe try a little white glue around the cap. If it still springs back use some of Roy's goo on the surrounds. Regarding the caps, I hope someone with more expertise chimes in but I don't see a problem. What are the implications for ESR? I dunno. I do know, from working on Snells, that Peter Snell was an advocate of "bundling" caps, so you're in good company. Kent
  8. Simply Speakers sells that glue. Maybe contact them and ask.
  9. I agree with Bill about replace those ancient wax caps. When I got my AR-3s the tweeters were shot (so was one mid) so I converted them to 3a's and because of that experience with tweeters I added the recommended Buss Fusetron Dual Element FNM 1-1/4 fuses. For your 4x's, AR recommends FNM 6/10. That document is in our Library. My only comment is these fuses and fuse blocks are clunky and a little hard to find. I wonder if there are other options. http://www.classicspeakerpages.net/library/acoustic_research/special_sections/additional_ar_documents/fusing_ar_speaker_systems_1/
  10. That's a standard phenolic ring tweeter (PRT). Parts Express also sells them, for a lower price. Our RoyC did extensive research to find a replacement for the 4x tweeter and found the classic PRT to be the best, albeit not perfect replacement. Ebay seller Vintage-AR sells these, mildly modified by Roy with his sealant. Those would be your best choice IMHO. His ebay store is closed until March 11. https://www.ebay.com/itm/194443157067

  12. How about a picture of the “butt ugly” speakers?
