Hi everyone. 

I put together the Bugle about a week ago and I can't get it to work.  I was hoping to use this kit to teach me a bit and I have so far learned a great deal.  I was hoping to get some troubleshooting pointers from anyone who could offer them. 

I have double, triple, quadruple checked everything and I'm certain they are in the right place.  Someone said something about mapping the dc voltages.  To do that I put the neg lead of the mm to ground and go about poking the positive lead to what I want to check right?  But where do I start?  And does the unit need to be on and a signal coming in?

Sorry for all the rudimentary noob questions, but if anyone can help me get the ball rolling I would greatly appreciate it.

When I plug it in and turn it on I simply get nothing.  No noise or anything.

Help, Please!

Thanks.

Ok, make sure pin 1 of the opamps is in the correct orientation.  Then install good batteries.  Measure supply voltages at the opamp pins 4 and 8.  Get that first.  What are your non-working symptoms?  No sound?  Bad sound?

On the 4 pin it reads -8.85 and the 8 pin reads +9.14.  All three amps read that.

There is no sound whatsoever.  No hum, noise, nothing.

I was messing around with the continuity function and it said there is a short between all four of the center pins of the rca jacks, to their connecting pinholes on the pcb.  Although I don't know for sure, that seems odd to me.  When I checked the first one I though I screwed up, but if all four are like that.  Should it be like that?  Did I fry the board with those joints?

You probably measured ground pins.  Are your interconnects working?  Seriously, more than half the BUGLE problems reported have actually been broken interconnects.

Interconnects work.  I just unhooked other preamp and hooked the bugle up with them.  Is the ground pin of the rca jacks the one in the middle?  Thats what I tested.

Anything else I can do to figure out where signal is getting lost?

Thanks agian.

Oops!  The center pin on the RCA jack should be wire to the signal (or +).

"Oops!  The center pin on the RCA jack should be wire to the signal (or +)."

I don't understand.  I don't see any other way that the rca jacks could be wired to the board.  There are the three holes for the outside pins, and the one in the center.  Could you elaborate at all?

Thanks

There is one smaller hole surrounded by three bigger holes.  The smaller one is the +.  Any of the three bigger holes can be wired as ground.  But though, if you are using the stock RCA jack, you couldn't have made a mistake there.  May be you should post a picture.

Jeremy,

I was in a hurry once hooking up the bugle and when I turned it on there was no sound of anykind. No music, no hum or static....just total silence.

First, I made sure that the switch was on, then looking closer, I noticed that the cables were backwards.

It's easy to make this mistake if you aren't paying attention and the components are on a high shelf.

Make sure the rca jacks on the side of the bugle marked "input" are cabled to the turntable and the side marked "output" are wired to the main amplifier.
