H Posted May 17, 2011 Posted May 17, 2011 Hi, in the link is a pic of a switch I have in my 5E3. It's going to be the standby switch. Does anyone know which way is ON on a switch of this type? The 5E3 chassis just has the word 'Ground' in this position so isn't much help. http://www.tubeampdoctor.com/en/shop_Switches_Optocouplers_Switches_Optocoupler/Carling_112_63_SPDT_toggle_Ground_Switch_in_80

You could always double check it for continuity in each position to make sure you have the right side for the desired operation.

Thanks, the schematic I have shows me how it should be wired so I'm OK there. It's just not clear which way the switch should be thrown to select standby or on.

It's just not clear which way the switch should be thrown to select standby or on. Oops! I think I did everything but (barely) answer your actual question, I have a bad habit of doing that sometimes I believe that usually the switch will lean towards the active contacts - so if it's thrown towards the side that gets wired, that should be the "On", away from the side thats wired should be "Off" Again though, a quick check with a meter should present the correct answer The open side (off) will cut power to the OT, putting it into standby mode.
mars_hall Posted May 17, 2011 Posted May 17, 2011 It looks like the switch may have a diagram on top that might help. A meter would eliminate all guessing for which of the two at the end you connect to and you want it in the off position for standby.
H Posted May 18, 2011 Author Posted May 18, 2011 I had a chat with the tech team at TAD who inform me that it's not a standby switch at all; it's a 'wire post' and the switch bit is there just to look nice in the 'Ground' hole... The build instructions are minimal to say the least

The build instructions are minimal to say the least I would still maybe contemplate using that spot as a standby, though with a 5y3 rectifier you don't necessarily "need" one per se (at least in terms of the start up)... I think it might be more useful in the long run then the ground switch - which as TAD already told you, is really just there for looks now. Back before there were grounded outlets, the ground switch was there to change the phase of the primary wiring, which could eliminate or reduce potential hum. Now with grounded outlets and three prong plugs it's no longer required.

On that note (re-tubing) I need to replace the tubes in my vibro champ, any body got any suggestions on a good source? Local shop good but pricey!

Lot's of good tube shops online... my favorite for new production has been tubedepot.com Good prices, decent selection, and they always ship super fast - great people to work with too.
