Those switches have mains voltage lamps, not LEDs. If they are OK, then the internal lamp (mains) may work without connection to the resistor.

Page one of the spec does describe it as "Two-way LED lamp"......

I would start with the existing 1.2k resistor in place, as before (if you find that the switch LED is too dim, however, then you could re-connect the switch LED to the other end of that 1.2k resistor)

 

Sounds like a plan...you're a Gentleman!

Thanks again

hi

yes, that switch meets the service spec (3A 240V) - hopefully it won't be supplied with the switch manufacturer's name emblazoned on it !

 

if you've previously serviced the switch yourself (and avoidied injury!), replacing a latched version like this should be fine. You'll need to find suitable supply points for the internal LED (9-24V AC or DC - i'd choose DC, if poss - the voltage range shown implies that the LED is already fitted with a current-limiting resistor - check polarity required, using eg. PP3 battery and a 2k7 (ono) resistor, in series)

 

Take all necessary precautions to make safe and secure connections between the switch tags and preamp cabling - insulated boots on push-fit spade terminals, or heatshrink wrap over soldered joint.  I see your solder-sucker in the photo - i'm sure you know the score!

 

As always, if you intend to open the equipment and work on the wiring, you do so entirely at your own risk!

 

Good luck with the repair!

 

Excellent...and thanks for the swift reply!!

The original led part of the switch has what looks like (and measures as ) 1.2K in series with the led.

Would that need to be changed to suit the new switch??

Thanks for the replies!!

I've attached a pic...showing 12mm hole for the switch.

Original switch has already had a rebuild....and has now past the point of no return when it comes to another

Hoping to stick closely to the 12mm aperture with the replacement....and there are some switches that I've found!

Would this do the job??....I'd be selecting the latching option

.There's a link to a .pdf showing the switch spec too....here >>>>>LA12 spec.pdf

It's been a long time!!

Think it's time I dealt with this one....before dropping off the perch (as we all do eventually!) in an untimely manner.

As it says....Looking for a power switch...green led push type ....for *extremely* vintage GP11 Pre.....????

Any thought please??

GP11 preamp circuit is included in this schematic : [url="http://music-electronics-forum.com/attachments/27361d1391726117-trace-elliot_gp11-ah350-ah500-mk-v-bass.pdf"]trace-elliot_GP11-AH350-AH500-MK-V-BASS.pdf[/url]

Steve.....that's the same collection already referred to in posts #2 and #3....but thanks anyway!

Hiya,
I also have a very early trace pre that is in need of attention. This one is the one with the two separate circuit boards, attached by ribbon cable, strangely, I also have a couple of the early RA500's, and one of them has a bad hum, so any chance of copies of the circuits ?
Thanks
Mike

Can't send anything without an email addy....you could download from the links in posts #2 and #3....!

Many thanks for the responses...and the info!!
Suspect that the GP11 could well be a MK1......handwritten serial/model number....hand-built look if you know what I mean!

Also have a similarly early RA500.....would be great to find a similarly 'early' circuit diagram for that...

[size=4]Thanks to [b]ikay[/b]....now have a circuit from '86...... [/size][size=4] [/size]

[size=4]Thanks again[/size]

Hi Folks....back after a LONG time.....
....hoping someone might have circuit for an early GP11....but suppose that any variation might help!

Perhaps someone could point me towards a source...?

[size=6]Can now report that after more than 23600 hits, this Bass is now sold!!

Thanks to all members for interest shown over the last year or so, and offers made, irrespective of whether, or not, the cash was at hand!!

Am sure that Dave will be very happy with his new baby....!!

PS...Watch out for my Vintage Trace GP11/RA500 Pre/power combo (Ex Kinks!!) and re-covered Trace 4 X 10 cab to appear
......another potential record there......I'm sure[/size]

THIS ad has run from March 1st......still a helluva long time tho'.....!

[quote name='phsycoandy' post='660769' date='Nov 21 2009, 08:14 AM']I trumped that considerably about, well must be 3 years ago now, I don't think he wants it sold really, just enjoys all the attention! [/quote]

[font="Arial Black"][size=5].....Ha ha.....but not considerably enough as I recall
....and it was March this year.....and 'cheeky' by your own words!!!! [/size][/font]

[quote name='richardd' post='641774' date='Oct 31 2009, 12:30 PM'] Perhaps if he lowered the price a couple of hundred it would shurly be snapped up,as around £650/700 seems a reasonable price.There you go another hit,[/quote]

He.......HE.........mind nit talkin' about me as if I'm not in the room... !!!

£700 is half the rrp of a new one........that would be really daft!!!

[quote name='phsycoandy' post='628392' date='Oct 16 2009, 11:07 PM']Should have taken my offer 10 years ago, just think of all the interest you would have earnt! [/quote]

[quote name='johnbiffa' post='616999' date='Oct 4 2009, 11:14 PM']Novel suggestion, how about a straight swap for an immaculate 1996 Centenary Gibson Gospel acoustic, made in Montana with built in factory fitted acusound pick up and tone control.

Unmarked instrument and that classic Gibson sound with OHSC

I'm in Yorkshire as well !!![/quote]

....That 's an unusual offer....hadn't thought along those lines!
Some pics would be nice if that's OK?

You play pedal steel too.......I'm a Hawaiian fan, and have a 20's Weissenborn!

Have PM'd my addy
Kev

Appreciate your suggestion....and thanks!!
Haven't yet tried a Martindale tester....but HAVE taken the amp to other locations, and am still experiencing same problem.
Cheers once again....

[quote name='lushuk' post='498209' date='May 26 2009, 06:32 PM']It is with deep regret I am forced to sell this bass to fund another purchase but hey ho that's life I guess.

So as per title its a USA 1998 black n maple, now the body is 100% unmarked maybe if you angle in the correct light you may find something but not in normal conditions! There a 2 marks on the head stock which I guess are pinhead size and are pictured below, It has been restrung one week ago with D'Addario 105's, it comes with the white original pickgaurd, moulded Fender case inc truss ross tool, fender duster, fender inspection tag and case key, also fender strap lock are fitted.
This bass has been loved and looked after to the best of my ability and I like to think its condition reflects that.

Im asking for £625 for the bass + postage or arrange your own courier or collection from Derby, or may deliver depending where you are for peterol money, any questions please ask away!

Thanks for looking Eddy[/quote]

.....Me too.....perhaps we can keep it going....!!!
