Cary Audio CAD-280SA V12R

decooney226 posts03-31-2020 12:30amIt's just 210 div by 6, per "rail" as you noted.  If you are handy, pull lower cover, look and see if it has those four of the thin silver'ish Audio 1 coupling caps.

Yes it does, took pictures. Few other spendey little caps too. I saw the sokeys (sp) fast recover. Clean as could be..looks easy to work on.
Has a logic board in the back, front? Everything is point to point.
Wire to the speaker terminals was the only thing I didn't like.
I don't think it was #20, very small. that's gotta go. I have some really good pure silver # 12, 16, 18 wire. 16 will work, twice as big as what's in there..There was a bit of resin, around, alcohol will take care of it..

Please do yourself a favor , don't start screwing around inside the amp . Play with the 4 or 8 ohm taps for the speakers , play with the bias , roll the tubes , use 2 , 4 or 6 per channel and try different power cords . But please don't put silver wire in there , if you must mess around use copper and make sure the wire you put in is both facing the same way . Wire in different directions sound different . Don't make me come over there with a baseball bat …..lol . 

If you are looking to keep a softer more veiled over sound the Audio1 caps are okay, not bad caps, just not great ones. If you want a little more texture, clarity, and musicality, many other caps sound better.  Did not realize the true benefit of front' end EL84 or 12BZ7/6922 vintage tube changes until after swapping out the little silverfish Audio1s.  Heard that amp with four different sets of caps between myself and three friends who owned V12i and V12Rs, all much prefer higher quality coupling caps in that amp. Be safe, it can hurt if you touch the wrong stuff in there!

Hee Hee, I won't tear it up..I'm just havin' a ball though. I got it sounding pretty darn good. Yea the Ruby out. I had 4 Volvo valves from Marantz # 9 I had way back, NOS never used.. I couldn't believe the change there.
BIG difference. I went to Teleies 12ax7, from all the 12BZ7s, man that is a raw tube for sure, lot of gain but tough on the ears.. If the guy was happy with that sound, he's like most folks I run into, too much bass in there life...protect those ears.... really.. Nice guy though..
I have a great set of 6550 too. Tung Sols, have to find um..great mids those valves, rock and roll delight..

Facing the same way, you crack me up.. If I do anything I'll probably do my treatment to the wire and give it a direction same as it comes off the spool...3 days in the freezer and 4-5 days on a cooker..This is pretty easy to work on.. No kidding not my first amp tinker fest..I've done up a few through the years..

Copper, why copper? I've used pure silver not clad, had some very good results from stock copper, to larger wire, from the speaker terminals back to the first solder joint. Just did up a pair of NC500.. Quit a sonic nugget..I did use clad there, add a little sparkle..

I'm telling you, the wire is maybe a # 20.. look, it's
spooky. Looks like the inside of a new Mcintosh.

Thanks though.. got any pointer I'm ALL ears Caps YOU prefer?

So what's the cat's meow? I'd love give it a go. I'll be listening for 2-3 weeks then look into it.  Give the cable a chance to settle and everything..

So what's the name brand you used?

Honestly though.. It does sound pretty good.. The planars are just loving them, tons of power. Even on 4 valve. pretty hefty..No bass duty, just monitor section...

I want to thank everyone, for helping, lot of fun...listen to music in the middle of the day...retirement is just wonderful..

Regards..

Why not silver wire ?   If do a bit of research it will tell you that high frequencies travel at a slightly different speed through silver wire than copper . That is why silver wire is commonly thought to have more highs . There is not more highs , it is just slightly smeared and that makes it sound different.
