Rusty Posted March 5, 2009 Posted March 5, 2009 Hi, Does anyone have or know where to direct me to get the wiring info for installing an L-Pad to the inside of my valve jr head chassis? I'm not looking for the box kind or grill attachment. I'm mounting this inside the chassis head itself.
Steven Lister Posted March 5, 2009 Posted March 5, 2009 1. Do a search on this forum -- there was some L-pad info. if it's still there it should return 2. www.sewatt.com -- I'm not a modder but I think that is the main link to everything you ever wanted to know about mods to a VJr. [edited - link corrected] Welcome to a good forum and good luck!

Eracer_Team Posted March 5, 2009 Posted March 5, 2009 Actually Steven .. sewatt is a dot com... It might seem like an organization but alas they go by www.sewatt.com Rusty most will tell you that attenuating the sound will darken your tone a bit.. but hey if you wanted the amp quieter then you take the tone you get. You may wish to just go with and external attenuator as opposed to the ‘bit-mo’ version of L-pad built into the back screen. Baring that.. the best bang for the buck is a variable voltage regulator that you build into the amp that power scales the voltages but doesn’t effect heaters to the tubes and doesn’t color the sound all the much either. And you can build a VVR circuit for the same price as the L-Pad setup.

LOL It should be an .org. I'll edit my post above so that no one is misled. Thanks for the bailout (I wonder if AIG' date=' GM, Chrysler, every-other-Fortune 500 corp. and any other wealthy concern that SHOULDN'T NEED or receive tax $$$ even said thank you?)[/i'] Hit every BLUE NOTE baaaby..., I'm going to play on:-"

And you can build a VVR circuit for the same price as the L-Pad setup. I've already bought the L-pad and it's not the Bitmo one. It's the same as the pic below. I just need direction on where the wires go. Can't see all of it accurately in this pic:
Eracer_Team Posted March 6, 2009 Posted March 6, 2009 I've seen this picture before.. In this picture the user has broken one of their OT leads, that's why the brown wire is soldered to the lug and the blue that's twisted with it has the standard quick connector with plastic on T3/T4. I'd say the OT has been changed on this amp since the color coding doesn't match stock. but.. Looks like they're using the 8ohm tape for this one... Looks like the wire from the 8ohm jack board (now green) goes up to the top L-pad lug the yellow from the middle Lpad lug goes back to the 8ohm connection on the jack board. not quite certain were they are connecting that black wire from the Lpad... But it looks like they're bringing that back to the common on the jack board. When I get to work I'll double check my other references unless Gil or Lay beat me to it. Unfortunantly Steven all the good stuff on this forum is gone when they switched servers a couple of years ago.. the "new" search function 'bytes' on the Epip/Gibson servers now... I see you asked the same question over at sewatt but not answered yet. I did find: http://www.guitarpug.com/2008/07/diy-wattage-attenuator-box looks like they are using the common for the - speaker on the last lug.
