Title: Too much bare wire on RCA jack? [resolved]
Post by: MilderER on September 28, 2022, 02:39:46 AM

Hi! I'm back with another newbie question. Do I have too much bare wire peeking out above the black RCA jack (see photo)? I'm pretty sure the white wire is touching the bottom of the cup--I just stripped a little too much. Am I okay to go ahead and braid the wires, or is that bit of excess bare wire going to create problems down the road? Am I better trimming the white wire a bit and resoldering?

Thanks,
Jonathan

This isn't an issue in this part of the circuit.  The place where I commonly see this and it is an issue is the green wire going to A4/A5, as removing too much jacket can allow the bare wire to touch the chassis plate.

Thanks so much, Paul. I'll push forward, then.

Speaking of A4/A5 (please let me know if I should post this separately), would a tight crimp on these terminals be responsible for the trouble I'm having inserting the 12AU7 in its socket? I managed to pass the glow test, but I had to really bear down on the tube and rock it back and forth a lot to get it fully seated. This is my first time with tubes, and I have no idea how much force they can withstand--or how tight a fit is ideal. Do things loosen up a bit with time? The 12AU7 did seem very slightly easier to insert the second time I attempted it.

The sockets will loosen up a little bit with use.

I'm glad to hear that. Thanks again!
