Hairball Audio said:What is the DC resistance (ohm tester) between one of the greens on your input transformer and each of the other leads?
terrydactyl said:BRN: 9.5
R: 2 ... (fluctuates a little)
terrydactyl said:I went back through the thread and read poster 'Darkus' had the exact same issue, same symptoms, and it turned out to be a bad input transformer... Maybe?
terrydactyl said:Emailed. Thank you so much!!
Can't wait to build the next one!!
idylldon said:Here's how I understand it:
Brown -- Primary Center Tap
Green and Blue -- Primary Leads
Yellow and White -- Secondary Leads (I've seen yellow labeled "cold" and white labeled "hot.")
Black must be an internal shield, but I've can't recall ever seeing it connected in any PM1000 channel I've racked and the black lead has always been cropped short.
ECS said:Just finished a Copper and it's working great! I just wanted to confirm you've changed the heatsink setup on the BA512... all the photos I see are of a large black heatsink but my op-amp shipped with a plain metal standoff screwed to the transistors. Is this how these op-amps are shipping now?
resilient said:Hi Mike,
Built an Elements Gold last night. It is unfortunately not working. I haven't gone through the resistors to double check all of those yet, but wanted to check in with you here. I get some noise when rotating the output knob, but that's it. Nothing through the DI or XLR.
I should also have a 500 extender soon to take measurements. I'll also try to find a way to post a pic of my soldering. Currently the pic is too big.
Any thoughts on the noisy output knob?
