Mr. Olufsen is an old friend of our photographer, Bud 'Rollei'.
What he doesn't know about fixing Porsche 917K body-work...
...isn't worth knowing.

Currently semi-retired from life in the FAST lane...
...Mr. Olufsen was called in; to oversee all the composite materials applications, needed to encapsulate the Space Egg R&D Dept.'s low-noise resistor.

Here, Mr. Olufsen directs the process of securing the element and lead-outs to the polystyrene substrate delivered by the placky-shape cutters.

Missed getting a photo of the way the resister was wound.

But looking back at the last photos...
...the loop of resistance-wire was taken twice round the ellipse...
...the winding effectively starting in the centre & flat-wound outwards in opposite directions joining the lead-outs.

Here's a picture of four different winding types.

1. Normal Spiral.
2 .Out & Back
3. Flat-Wound.
4. 'Ayrton-Perry' Winding.

The 'Ayrton-Perry' winding uses 2 conductors & 4 times as much wire, as the others.

The winding we used, is kind of a cross between types 2 & 3.

With the wire-wound, now wound...
...we need some encapsulation, for the component.

It works just fine, how it is, of course...
...but we can't let those jazz-age funky-Professors at Mullard down...
...with a second-rate finish !

The resistance wire is a bit 'springy'...Boooouuinggg !...
...and also wrapped in Teflon...
...which as we discovered earlier; even Gecko's can't stick to !

So Mr. Olufsen with his experience on Porsche 917K bodywork; suggested some 'matting' was added...
...killing 2 birdies, with 1 stone.
Springy resistance-wire :- flattened.
Non-stick Teflon surface :- stickable.

The resistors substrate & element, was covered in fine Polyester thread...
...We used Coats Drima #180...
( a good colour for 'invisible-mending' your jeans; shame about the rips ! )
Saw somewhere, that 'red' is lower-noise ... or something; but we didn't have any, so light-blue it is !

Bud's photo shows one of The Space Egg Corps. R&D boffins...
...Miss. Vero; a cool 70s' chick, for sure !...
...and some familiar lecy bits & bobs, to see how the product is sizing up.

.Ho...Ho...Ho...

" Shut-up beardy ! "

Off next to the paint-shop, for our custom-resistors funky-finish !...

Gerry, down at the paint-shop, encapsulates the resistor, with repeated-coats of Acrylic-Resin...
...then a layer of colour...
...after which, another Acrylic-Resin layer...
...then component marking decals...
...& finally, 1 last coat of Acrylic-Resin.

Jees Gerry...
...you bin busy dude !...

( anyone care to speculate on the component value ? )

What about 56nF (I do have 100's of them all values )

Hi FdW

YOU JUST WON FIRST PRIZE !!!...

...in the 2012 Christmas competition !

Your original-Mullard 'funky-Professors' lab-coat ; will be in the post to you, first thing on Monday morning !

Sounds like you have quite a large 'shoal' of Tropical-Fish there...
...same here !
They all seem, good as the day they were made.
Could be a good choice for the new preamp !

Used to curse the darn things here; back in the day...
...before we had a digi-capacitance-meter...
...never was QUITE sure, what values they were !
Was pleased when they were phased-out for printed parts.
Now though...
...we miss our little-fishes, swimming around between the other parts, on The Space Egg Corp. boards.

Good to hear you've still got a large-stash from the swingin' sixties FdW...
...the funky-Professors at Mullard knew a thing or two about audio !!!

Cheers.

Didn’t they look great I excavated this one from the bottom of the ‘spend-electronics-box’, it was built in 1977 and still looks great (3 way Bessel crossover). (See the odd one out?). (These where branded Philips). (Mustard was never my favorite taste )

P.s I'm looking forward to receive the lab coat

[The Space Egg Corp]

Hi FdW

Thanks for the Bessel board pic...
...that's gotta be the best dish of fish I've even seen !
Quite an aquatic expert, I'd say.

Yes !...with your clue...we spotted the blurry-blob of mustard !
( must have been constructing during lamb-chop dinner ? )

Those Mullard resistors were a bit of a bitch to ID as well...
...gold-braid on the ends !...and all.
Oh well, back in 77, we had Ohm-meter ( analogue ! ), just no MF digital-meter.

Searchin' the W.W.W for the mysteries of Mullard...
...we happened across a little pic. of our very first TT preamp board !
I figure we got this little baby around 77 as well...
...distinct memories of listening to 'Trans Europe Express' by Kraftwerk, come to mind.
More mustard than fish on the old Mullard preamp board...
...N I C E !
I think we're gonna have to do a teeny-weeny aside story on her soon !
( watch this space, Mullard maniac's )

Cheers.


Si.

PS...sorry FdW, there might be some delay, gettin' your 1st-prize, of the original-Mullard funky-professors lab-coat to you...
...the Board-Directors at Space Egg; have felt obliged to have campaign badges, gold-braid, and tropical-medal-stripes added to the garment...
...in honour of the best-Bessel !

The Directors regret any inconvenience this may cause.

( the swingin'-sixties were never predictable ! )

Between coats of acrylic-resin & paint...
...Gerry dries the DIY resistor over the grill...
...and takes a break for his fav. lunch...
...of grilled sausage & chips !

( sorry about the blurrey-pic...
...our photographer, Bud...
...got in late, after New Years Eve...
...and couldn't find his tripod ! ).
