First time builder - failed voltage check [resolved]

[Larpy]

I don't know that BH sells tubes.  If not, and you're leery of ebay, I recommend the online vendor Tube World.  Not the cheapest prices, but every tube has its test results provided on the website.  That's rare.  The '60s Sylvania for $24.99 is what I'd get if I were you, but there are lots of good options for under $50.

Tube World ships quickly as well.

so while im waiting for a new 12au7 to come in....  ebay guy still hasnt shipped,  Im getting a short on the trs jack at the resistors.  Should I  desoldier the resistors to see if they are bad?  I was looking at mouser for replacements but im not sure exactly what to get.  2.49k ohm 1/4w,  but will any of them work if they are threw hole?  I kinda want to start all over now just to be safe and now that i have the magnifying glass and all.  When I place my leads on both sides of resistors,  they read 0.00.  The 270k 1w resistor read OL but I think thats because it hooked up with the cap?

The jack shorts the outputs intentionally when no headphones are plugged in, so there's no issue there.

You need to replace both LEDs on the 9 pin socket and double check that the black wire going to the center pin of the 9 pin socket is well connected and well soldered on both ends.

LEDs should be here sometime today,  ive already got everything unsoldered there now.

Finally,  its working!!!!!

THANK YOU PAUL!!!!!!!!!!

Got the LEDs in there all nice and neat and all voltages got into line. 

Thank you so much for walking me threw this and putting up with my crap. 

Time to sell my darkvoice
