NAD 1996 JCMSlash Sig - Filter caps??

[fusedbrain]

Picked this up a couple days ago. Got it for about what a 2555x re-issue would sell for, so I think I did OK. The amp is 100% all original.
I don't think the chassis has ever been out of the headshell. It was a local pro's backup for his JCM800, and it's been in a road case for the last 15-20 years with maybe 10 hrs on it in that time. Dude says he hasn't played a note in 3 years, and was just cleaning out his basement junk. There was a ton of interest in this amp when it showed up on the local buy and sell, but I was the first one willing ( or crazy enough ) to drive an hour through a snowstorm to show the dude the money. Glad I made the trip

I was just wondering what you guys thought about the filter cap issue with an amp like this? If I turn the guitar volume off and crank the master vol, there's no 60 cycle hum, and very little noise at all. My first thoughts were that its a 22 year old amp, and should just swap out all the electrolytics, but at the same time, there doesn't seem to be any issues and I'm wondering if I should just leave it alone? The amp does sound really good.

As for how it compares to the rest of the herd, I've never owned an original Jube, but compared to a 2555x re-issue ( which I do have extensive time with ) this amp is not as bright, has more bottom end, and quite a bit more gain.
It actually sounds a lot like my Wizard MCII.

I used to have 2 of those. There were 3 Revisions of the Jubilee. The Final Revision was when Marshall took the Silver Jubilee which was then absorbed into the JCM800 Line & you'll notice those have Black Tolex, That was the Final Revision. The 2555SL is an exact version of that final revision.

The 2555SL was based off that final revision, it is the same as that one.

I've had a bunch of Silver/Black tolex Jubes, and have played the Slash version..I did think the Slash had a bit more low end than any of my originals from 87-89. But Identical otherwise. And, I agree that there is a similarity to a Wizard circuit with the expended lows/highs of the Jubilee. The high end seems to be almost Identical. Great amps.
As far as the can caps go, I had an improvement in my 87 2210 when I swapped them out, tighter and a little more bite. But, all 3 can caps had small bulges on the bottom in the middle of the cap...so they needed it. If you don't see anything leaking/bulging, and it sounds great, I might just leave it....but, I don't think it would hurt to change them either.
I highly recommend the ARS Can Caps, I've heard the F&Ts can change the tone a bit. The ARS that I used, the tone did not change at all.

Congrats... great amp! Did you get the cert and cover as well? It sounds like your caps are fine- I wouldn't mess with them. If you do, I agree with the ARS suggestion all the way!

Thanks. No I just got the amp and the road case. I pulled the chassis out of the shell today and the can caps look pristine. No bulges or leaks. In fact the whole damn amp loos like it was made yesterday. Probably just going to leave it for now, and just play it.
Not a ton of info on these Slash versions, but seems that they are identical to the regular Jube's, except they have Dagnal transformers vs the Drakes in the original 80's Jubes. Might account for the slight difference in tone.

Nice score. The logo is WAY too high though. If it was mine I'd have to fix that.

I've played too many amps from the 60's and 70's with original cans that were still fine that I wouldn't sweat a 90's amp unless it showed physical signs. Sometimes though if an amp is unplayed long enough the cans look ok but have dried out internally. But I don't know how long that would be. I doubt 3 years is a big deal.

I have two of them right now... Marshall always used Dagnall for the 100 watters so rest easy.. youre good to go. The only difference would be with one of the early 2555's that had a few resistor/cap differences, which some experts suggest offer only a minimal difference? who knows- never tried one.

Try putting the lead master on 10, full up.. and then bring up the output master- at around 6 it should fill out nicely. Punchy, and clean.

Never noticed until you mentioned it.
But yeah, I kinda agree. Now it's gonna bug me

I was just wondering what you guys thought about the filter cap issue with an amp like this? If I turn the guitar volume off and crank the master vol, there's no 60 cycle hum, and very little noise at all.

The amp does sound really good.

If it were me, I'd take it to a tech and change all the caps. If you don't want to do that, you could have your tech test the caps and see what he recommends.

If it ain’t broke don’t fix it.

I'm in the panhandle, unfortunately, Destin area. My home of record is in Cocoa Beach... cant wait to get back!

I was just curious since i sold both of my 2555SL Jube's in Florida. I'm in Palm Beach County.

Agreed.

My Peavey Butcher is 33 odd years old and still has original caps.
