I am just at the ordering phase at the moment. Trying not to let costs get too much...... but just ordered $30 of obbligato caps.

I doubt i will get time to finish it before christmas, very busy at work at the moment.

should be fantastic when done though... fingers crossed.

schematic here: http://www.diyaudio.com/forums/showt...626#post826626

Initially i will remove negative feedback.

The odd thing in all this is that it is only one one side, where I used the same sockets all around... so, I might tinker with the left side sockets a bit, but am all but certain I know which two sockets are the problem children. Jbweld on the pins will not work as it is epoxy, and non-conductive.

I mean, how long could it really take to change out a couple of sockets?

if you can snip the pins as suggested it should be pretty easy. Heat the joint and pull the pin while it's hot. Suck up all the solder remaining and start over.

Al, how experienced are you with bribing women? okay, don't answer that.. anyways, I wouldn't mind taking a look at it on Wednesday, but I'm not sure how long I can stay out I have the best (cheap) tool ever for dealing with this stuff though. I purchased it from Consolidated Electronics, Incorporated. It's a combination solder sucker / iron thingy.. for around $25. Much better than the Rat Shack bulb version. Problem is, they don't sell replacement tips for it (but mine lasted 3 years or so), but disposable tools are okay in my book. I'd recommend picking one of these up, they are very easy to use and will improve your desoldering confidence 10 fold

Bad news is I have some strange ear thing going on now, so I won't really be able to enjoy the Bijou ...

Senior, you and I have many other matters to attend to, like a trip to Tanners, sorting a Mouser order, looking at a BOM, oh, and rebiasing the BH. But I was counting on you hearing the Bijou... if that is shot, I may as well tear her down to replace sockets - AFTER you concur somewhat that is the issue.

You could bring some of those 9 pin pcb sockets (assuming you got them), as the teflon hasn't made it in from Taiwan.

I will say I am usually better at making arrangements with the women I am not married to - if we have two in the mix (yours and mine), I think we are hosed.

Run a piece of vacuum hose from your running car, through the window. Install a piece of telescoping antenna into the end.

Get busy! LOL.

Have you considered just cutting the socket legs, one at a time?

I would give ChipQuik a try.
It's made for SMD rework, but it's worked really well for me at removing multi-pinned through-holes.

Pabbi, did you order teflon or ceramic sockets?

I have teflon coming for the prototype electrostatic amp... and already have some ceramics hanging around. This is really more about hassle factor than anything else. Edit: Especially since it is perfect for hours on end, then a little crackling, only audible in between tracks. Even odder, when it is constant (like after leaving the amp on all night), it clears up pretty much with a simple power down and back on.

Right on the border of flee or fight.

That sure is pretty - but you know good and well I need TWO... the Caddocks are a nice touch. How about Rikens for mine?

Husky: The balanced Bijou makes Rush just that - absolute precision, and balance. Peart's drumming has never sounded snappier, the guitar lush, and Geddy's voice, well, listenable... not exactly like a dog caught in barbed wire. :-)

i actually used to be the biggest Rush fan when i was a teenager - i had all their albums on cassette up till the Presto Tour (i much prefer the older stuff). i was 14 and my mom picked me and a buddy up in Limo for the concert. if i remember correctly, the opening band's guitarist, Paul Gilbert of Mr. Big, used a power drill during a wank-out solo and caught his long hair locks in the drill bit. ha-ha...sorry, a bit off topic.
