Very interesting information!

You guys are awesome for the amount of knowledge :)

Making my cap order tomorrow, I like to have enough caps for any piece of gear i buy, that way im sorted and can rebuild when i have time. Just waiting on word from Roger the SSL tech around here, We're gonna chat tomorrow and make a plan. Unsure about Panasonic or Nichion or Elna, but thats for another discussion.

These Spare cards... any worth in keeping them? or put em up for sale...? ...

Thanks for the replies!

What bolts holding the meter are you talking about? The screws holding the cards down ? I didnt notice any bolts, but i wasnt looking for any. . .

Sometimes its the meter nuts holding the board on to the meter. The bolts inside the meter come loose. Remove the board, make sure the bolts are tight in the meter, refit the board.

that seems to indicate that it is connectors that are giving you problems. Spend your time going thru and cleaning and re-tensioning the connectors not recapping. That will probably fix your problems if each module checks out well already.

Then, when the system is working correctly, you can evaluate and see if recapping is needed. Keeping the activities separate will cause you less grief in the long run.

No problem...give me a day or two and I'll try to come up with a ramble on a new thread about how Paul Frindle and I came to spend 1987 in a garden shed, things to do with a solder sucker when bored, and why Dire Straits "Brothers in Arms" album sounds really good through a G series EQ...

Sadly, I've ridiculously few photos - just shows how times have changed in the digital age.

Cheers, Andy

Hey Andy.

Feel free to ramble on about anything. You have any pictures from back then?

Could you talk about the changes from E to G and the design of the 292 eq.

The x4 comment is a now a classic.

Thanks for being here. 8)

P.S. sort of vaguely in answer to the original question a bit: for electrolytic caps in the audio path of the 4k/6k it really doesn't matter too much what value you use for most of them, as long as you don't go lower in value or volt rating of what was in there originally. Mostly we just fitted the physically largest caps we could at the time - even so, the low frequency roll off across the desk was pretty bad (compared to the 9k for example). So whilst going 10x bigger might cause strange noises at power up (even stranger than you get already), going up to double or 4x in value (now that caps are much smaller) is unlikely to do any harm and might do some good.

Just never ever change the values of any of the ceramic caps, or change them from ceramic to anything else. At least as long as you've got 5534s fitted. 5534s are a complete pig to stop oscillating.

Cheers, Andy

Hi,

We didn't upgrade any of the centre section cards for the G series, there were only two changes we made IIRC to the 651:
  • It was painted grey
  • The Monitor Level pot had an extra '11' added  - so that you could turn it up to 11. (Yes really, we made a Spinal Tap joke - the really funny thing was that hardly any customers believed that we'd done it as a joke, they thought we must have changed the circuitry. In fact on both E and G 651s the control actually goes to 10 1/2)

We were going to upgrade it, but when we started looking at it we just couldn't work out where to start, and there wasn't enough money in the budget to fund a complete redesign.

The much later G+ upgrade sadly I don't know anything about, sorry.

Cheers,

Andy
