72 board pulling & FlatcapII

Hi Dave,
Not sure about the flat cap thing as I have only a Hi-cap. Pulling the boards on my 32.5 was easy (do it with the power off). I think there are some pictures on this site of 32/72's with the sleves off so you know exactly what to pull.

You remove one card per channel. They are towards the back center of the beast as viewed from the front. All the cards have serial numbers so you can double check mine are 323's.

Have a look at

This list all the serial numbers so you can identify all the bits and pieces.

Whilst you are in there clean the conectors by plugging / un plugging the cards a few times.

The tape channel was the best for CD on my pre and this is the general consensus. If things are harsh always have a look at how close the power supply is to your sources/preamp.

Regards

Sorry please read tape as tuner.

Simon - thanks for your help.

Took the beast apart.. there seem to be a lot of unused connectors with no boards...

However, on reassembling, the input selector knob (which has been dodgy for a while) has finally died and will not click into position (tape/cd/phono) etc. I knew I would break it...
Off to the dealer now for surgery.

Re. the harshness problem, power amps and power supply are already as far away from the 72 as the snaics allow. What to do?

Dave,
Sorry just read your reply. Looks like your boards have already been pulled. Good luck with the repair.

Still sounds harsh? Hmm What is the 72 and the CD sitting on? How far apart are the CD and the Pre? Also how are you powering the system?

If you are using a 4 way block throw it away and look at getting either a grahams hydra / using unswitched sockets or a Maplins 4 way plug. Personally I have a 6mm dedicated spur and a DIY hydra (cost about £30 sounds like adding a HI-Cap!).

Also do a search on my system sounds harsh - There was a post on this a while back and I think they covered all sorts of things.

Coupla things on the 72.

Not only can you remove the phono boards, you can also remove the Tape Out boards. There is some debate about whether removing the tape out boards is a Good Thing, but thought I would pass along that it is fairly easy to do.

Other thing is that the difficulty, if any, is not in removing the boards but in replacing them. It is possible - easy in fact - to put the boards back on the wrong pins. Set up this way, the 72 will produce a repetitive clicking sound though the speakers. Nothing blows up, not a big deal, but just thought you should know.

As to the harshness, the harshness of my CD3/72/HiCap/140 system was unsolvable in the 3 years that I had it. Now, there are two things I was not able to do.

1) Black SNAIC - was not out when I bought my kit. Came out later and I *could* have gotten one but chose to dump the kit instead.

2) Dedicated mains. I was living in apartments and couldn't do this.

Since dumping the kit, I am "back in the fold" with Naim using a Nait 5/FC2 to drive Allaes. Main sources are an aging SONY ES series CD player, a DVD player, and an LP12.

No harshness. Not a hint. Sounds like the 72/hi only mucho cleaner. Am using current cables with this new kit...so its possible the Black SNAIC would have done the trick with the 72/hi setup. I may never know.

To my ears, the CD5, the 72, and the 180 all have a hint of harshness. The Sony ES series members that I've heard do not; which is why I owned one for 6 years.

If you've got the cash, a hicap on the 72 is likely to help a bit, as is a much better CDP or a 250 or, probably, to something in the new series (202/200?). Or a Rega P3 and a bunch of LPs....Tough choices.

Regards.

Oddly, adding the hicap to my 72/140 combo *added* to the harshness (!). Down to the grey SNAIC perhaps? There were other gains of course, and the CD3/72/140 combo had harshness already, so the hicap stayed in fer sure.

My system was harsh with the CD3, but not just with the CD3. Other sources were also edgy.

Very happy now in NaimLand and will likely move up when funds allow. Gotta start saving for my son's college and all that.

I am currently running my phono stage into the tuner input on my 72 can I improve on this with different cards? thanks
