Crack / Re: 12au7 not glowing

« Last post by watonwak on Today at 10:40:47 AM »

Thanks Doc, it was the B7 end that had come off. It had snapped at the joint with not quite enough slack so had to replace the wire, but its all working great now!

12AU7 heaters are not getting power. Check and maybe reflow the green wires connected at the A4/5 and A9 socket connections and also the other ends of those wires at B7 and B8.

Crack / 12au7 not glowing

« Last post by watonwak on Today at 09:01:10 AM »

hello,

i was doing some rework to my crack with speedball, tidying up joints to try and fix some intermittent noise, but now my 12au7 and its LED's no longer glow, and i am reading about 180v on 0A and 0B on the small board. Have i messed up something obvious? All other LED's light and so does the 6080. Thanks

Edit: I checked the LED's with my meters diode check and they do both glow

BeePre / Re: Resistance Check on 52

Good Morning Paul,

Am I just looking at the (2) 130 ohm resistors and the (1) 330 ohm resistor  for each tube? Or is there somewhere else I need to verify too-

Because, After triple checking  these 6 resistors ( 4 130 ohm and 2 330 ohm) I am positive the resistance readings across the resistors themselves, and the terminals they are soldered to are the same?

Perhaps I am just not looking at the right spot? Probably just another noob move out of me here-

Bottlehead DAC / Re: Is the Bottlehead DAC repairable?

Which input are you using? USB? TOSLINK? Coax? It would be helpful to have more detail on what happened, what you have the DAC connected to, what power supply you are using, what apps you use, etc. Also tell us if you had changed anything in the system right before it stopped working, like a new source or any software, firmware or operating system updates to the source.

General Discussion / Re: Tinnitus

Thanks, everyone, for your responses. It‘s been almost eight weeks now, and no relief. I saw an ENT, who prescribed prednisone for a week. I‘m tapering off now. No change. If anything, it‘s worse. I tried listening to a record yesterday, at low to moderate volume. It hurt. And afterwards the ringing increased.

Hang in there. Prednisone itself, especially at doses that require a taper, can make tinnitus worse (hopefully a temporary worsening, since pred is prescribed very often for tinnitus.) Prednisone, if you haven't taken it before, has other unpleasant side effects (for me, I get rage, feelings of doom, and insane hunger. Oh, and insomnia. Thank goodness I haven't gotten the tinnitus side effect from pred.)

If you aren't averse to Reddit, there is a subreddit for tinnitus that may be useful. Let me see if this forum will let me link Reddit...

The blue looks great, is that a variety of Illusion blue powder coating?
