AR 98LS Info

Madtech, your woofers have tons less corrosion than mine, mine have a lot of white patches on them and the baskets are pitted. Still sound great though. I have all the caps if you are still curious about what I bought and what values they are, I'm just afriad to recap these working through the speaker whole, all my other recaps have been done with crossovers that are removable. These are epoxied in so it will be doing soldering in a confined space which has intimidated me into waiting. I bought all Jantzen for the caps that were off the top of my head 12uf or under and NPE's from parts express for the larger caps.

My magnet assemblies were covered with a small amount of rust and white colored pitting. I used a large steel finger nail file to get rid of the white patches\rust and then coated them with a thin layer of lithium based white grease.
A re-cap will happen but not right away. I hate soldering through woofer holes too but I guess it's all part of the fun ! Good luck.
 
Okay so you were victimized by corrosion as well it sounds like. Are you going to replace your binding posts and wire clips?

I think I'll keep the original binding posts. Other than a re-cap I have a bit of sand paper work to do on the cabs (that will have to wait until spring) then I'll be done.
My AR9s are next for a re-foam of all 6 drivers and a re-cap. Should be fun!
 
You have AR9's???? Wow...I can't believe you didn't just skip to those ;)

I would love a pair of AR9's, haven't been able to find any for a reasonable price, how much did you score yours for?

I definitely had to do some sanding on the cabs but in the end they came out pretty decent, I haven't figured out if I'm going to just put oil on them on an ongoing basis or poly them at this stage.

My binding posts are pretty iffy I probably just need to replace them, I'm going to also cut off the clips strip the wires and re-crimp them.
 
Inner dust cap manufactured and installed on the 8 inch woofers. My Simply Speakers MI2000 black adhesive was screwed up by the temperatures encountered during shipping (they're sending me two free ones when it warms up) so I had to use black silicone to install the inner cap. Tomorrow, after the silicone cures, they will powered up for the first time ! Should be a blast. One more picture to go.

Woofers are in the cabinets. Man can these babies sing ! I really can't see a re-cap making them sound any better but I will do it anyways. They sound great at low volume but when the volume knob hits 10 o'clock they really start to shine! I'm definitely impressed. Can anyone pick out the difference between the two cabs? I just noticed it when I took the pictures. AR9s are next !

Technics SU-V909, 125 wpc into 4 ohms. I might hook the NAD up later but I'm having too much fun right now. My neighbors, I'm sure, are also enjoying the "fun" ! These things love power!

I will be interested to hear how the 909 performs in the longer run with your AR's.

Its got tons of current and headroom to spare that amp.
 
Any placement tips out there for my AR98LSs? Should I get them off the floor?
I bought them from the original owner but one speaker has yellow trim on the baffles and the other has white which is kind of strange.
 
Hey Madtech, just an FYI, I finally recapped one of my AR98LS's. I had put it off for months and months because the process looked to be horrific with the quantity of capacitors, the density of them on the board, and the fact that the board was not removable so I would have to work through the woofer hole. It took me literally 4 hours...for 1 speaker. This includes epoxying them in, twining the caps together, cutting the old ones out, etc. etc. I also replace the terminals. Truly the most painful recap I have ever done. Of all the speakers I recap'd this is the most dramatic improvement in SQ of any of them due to a recap. Just a heads up.

Next one will be done tonight.

Well done on the recapping, any chance of some pics ?
 
Sure, I will snap some when I do the second one. What would you like pics of? I have a schematic somewhere for the 98LS but I'll snap one of the train wreck of what it looks like on the board of one of those things. It's like things were just glued randomly to a masonite board that is epoxied to the back of the speaker cabinet i.e. if you tried to remove it to work on it it would probably snap. Freaking nightmare.

Before and after pics would be great, i am sure Madtech would find them helpful.
 
Will do. I also have a bill of material for what is necessary if anyone wants it but as usual, I order Jantzen from Parts Express as is my preference so often times the value I need is missing and I need to order multiple caps where one would work. Someone wanting to use Solen or Madisound or Dayton might have a cheaper/better experience than I would.
