1176 Rev B 'Blue Stripe' - I need a HUGE favour from any owners.

Hello to all.

Had to post this here rather than the Geekslutz as this is very specific to the original Rev B 'blue stripe' 1176.

I have just shipped mine over from the States to me here in the UK and as there was a lot of other gear, I foolishly (in hindsight) had it racked in a shock case.
Too cut straight to the point - the face plate, along with all pots, the meter and buttons, all remained perfectly mounted to the rails, whilst the entire casing broke free - snapping all wiring to the faceplate itself!

Looks like there are two 'L' brackets - like a rack ear in shape - that should be fixed to the faceplate at each end and the casing would then screw into the perpendicular face of this bracket --- and these have sheared right off of the faceplate.

OK - so this is a MASSIVE ask - but is there anyone out there that owns a Rev B that would be willing to unrack, lift the lid and take a few decent pics of the wiring to the faceplate and meter?

This is NOT an attempt to get any schematic or anything - I am MORE than happy to email the photo's of my disturbing mess to anyone willing to assist to prove my situation.
I have found a few good ones online but they usually focus on the circuit board and component layout etc and I really need to see more of an angled shot from the top down towards the back of the faceplate.

I will try to upload a pic after posting this initial message.

Thanks for any potential assistance with this - I do realise the pain and annoyance in being asked to even consider helping - but perhaps someone out there has one on a bench or has one out of the racks about to go up for sale etc.

So the 1st line of repair for me is going to be to somehow try to fix the 'brackets' back to the faceplate, then I would like to do the wiring myself if possible - hence this bizarre request here on Gearslutz

The reason I have assumed this will be fairly specific to a Rev B and hence pleading for such mercies - is that many pics that I have seen online of other revisions insides show the wires terminating in different areas on the PCB's?

My BIGGEST areas of concern are the 4 x thin wires that go to the meter buttons - mine have sheared off right on the button terminals, so I literally need to know where red, blue, orange and green go ... then I have a few thin wires coming off the VU itself that I have no idea where they ran to?

Once I have figured out that side of the mess, then I will move to the grey looms that feed the pots etc, as they are at least reasonably grouped and a bit easier to resolve?

Here are a few pics of the button/meter mystery as it stands.

I know, I know - I am expecting a lot of lecturing etc - there is a long, long story to the reasons and history behind the circumstances that have led to putting myself on the knife edge like this by demonstrating such terrible shipping care, but like I say - the entire story is extremely long, boring and cannot be changed unfortunately.

This is a horrible way to learn a lesson, but I really would not in my wildest dreams have imagined this kind of 'accident' - dropping, smashing, bending, poor packaging etc - that I would expect, but this is a whole new level of shipping nightmare.

Naturally, in hindsight, an item rack mounted is a LOT less protected when it comes to rattles and shakes than something wrapped in layers of bubble etc - and this is something I now will take to my grave unfortunately.

Bracket that would attach faceplate to casing:



Sheared off the faceplate:



Meter button wires:



The nasty side (button terminals bare and red/black wires off meter a mystery):



A little less scary - pots:



And the rest of the 'pot' wiring - orange/white I have traced:

OK - apologies for bombarding with photo's - I now need to get some sleep as mentally shattered!

If anyone can help or point me to a potential source of assistance, it would naturally be greatly appreciated.

Thank you

I learned the same lesson about 13 yrs ago with a shipment of 4 racked vintage Altec 1567a units from CA to MA. It was a sad day when that box arrived! It sounded like a morocco there were so many tubes, trannys, caps and other bits rattling around.

I am sure someone can post a pic for you. In the meantime a google search did provide a few images of the guts.

Gotta love search engines - I had searched earlier for Universal Audio Rev-B, Blue Strip 1176, Urei Blue Inside etc etc ... and only found one good pic by googling Urei Golden Caps (mine has the champagne coloured large caps etc) and this pic shows identical colour wires and PCB location for the meter button wires (orange, green, blue, red) - but as per most Urei pics, the angle is facing away from the faceplate, so you can't see where they go on the button terminals ... now I click on your search results and there is ANOTHER pic of an old Urei also with the champagne caps - but from a more vertical position!!!

Moral of the story - keep trawling with different search strings!

Cheers for that

Hi, you can get me on [email protected]

I am away from the studio for the day but will be online and access to mail etc.
So if you are anybody else needs any additional pics to show exactly where which 'snapped' wire terminates to ensure an accurate trace back to the correct lug on the terminals etc, then please let me know and I will take those as soon as I get back this evening!

Having Googled a bit more last night it looks like the red/black from my meter MIGHT go straight to the meter buttons, but what is a mess to figure out for now is that the red/black from my meter are hanging free/loose, but there are also corresponding red/black wires (also loose) already terminated to the buttons, so I guess logic would say that they must daisy chain in some sort of series to be able to register each alternate button selection ... so this is some extreme detail that I need to figure out.

Thank you so much to those offering to help so far!!!

Regards

The welds between the front panel and the main chassis are small and can break fairly easily, have seen this a few times before. I don't think any kind of glue or epoxy would be strong enough or reliable. I would carefully install some small screws with countersunk holes, or find a shop that can spot weld the panel back in place.

The wires are color coded and the schematic shows them fairly clearly so if you have the schematic, figuring that part out shouldn't be too hard.

Hi

I am no expert on Urei products but found this link on the web... I hope it helps.

I can't believe they would rely on those tiny stud welds to support the entire chassis!

Well, I know one company currently producing valve gear that uses pressed in studs to hold the faceplate to the chassis. I guess they didn't want screws visible on the front panel. I had the pleasure of servicing one that was in a live rack that took a tumble and believe me, nicely countersunk screws look just fine!

Many thanks to all with suggestions, links and sound advice.

Bryan has kindly emailed me some fantastic hi-res shots of his Rev-B and that long with David and Geoff's nudging towards the manual should see me home.

The only part that at first glance looks a bit tricky is the wiring to the Input pot (the 'dual' pot) - as it looks as if 2 x 3 core wires terminate there and the whole what goes where just on that pot alone looks puzzling right now - hopefully the manual schematic clears that up?

I have found a contractor here that specialises in aluminium welds (allegedly trusted with 1mm bicycle frames/parts) who is happy to do the job if I choose a re-weld.
He is very expensive (due to his minimum charge as he probably deals with much more labour intensive jobs etc) - so I have actually been considering some nice countersunk screws as per David (and others) thoughts.

Times like these on very dark nights that places like Gearslutz shine a very strong beacon!!

Here's a wiring diagram for the Input pot. Two shielded cables connect to this pot and 3 shielded cables connect to the Output pot.
