Crack "Clicking" noise from headphones

[DirectAssault]

Clean the tube pins

Best way to accomplish this?

Try different tubes

I currently only have the original tubes, I heard that replacements are a bit pricey

[DirectAssault]

Delete the DAC and feed the Crack directly from the PC headphone jack and see if that changes, or solves the problem.

This was already attempted, I disconnected the DAC from the amp and just had the amp headphone plugged in, the problem persisted.

He’s asking you what happens if you don’t have the DAC plugged in but you do have the headphones plugged in.

No change, same thing

I'll keep that in mind when I go out shopping

[DirectAssault]

So I got my voltmeter and I'm currently testing things out;

I'm looking at the terminal resistances, and everything is normal except for 3 terminals.

Terminal 22 I get a value of 1 Ohm instead of 0.

And Terminal 7 and 9 are really off, I got a value of 9 Mega Ohms (the value keeps climbing up) and 5 Mega Ohms (the value keeps climbing up) respectively. Neither the values I mentioned on 7 or 9 were the original starting values, just when I stopped checking because I needed to get my girlfriend to look at the voltmeter too, along with changing the probes out. I think they both started at around 4/6ish. Considering the large discrepancy, I am hoping that these are expected values with the Speedball mod installed.

I'll probably stop here and not check voltages until I get some sort of response

The Speedball will alter the resistances at 7 and 9.

1 is very close to 0.

The Speedball will alter the resistances at 7 and 9.

1 is very close to 0.

It'll take that as a blessing to continue...

A6 has a voltage of 70 instead of 90.

A3 has 1.5V instead of 0

B1/B4 has 70 instead of 90

All other voltages checkout, including voltages checking out on the speedball upgrades.

@PB What am I advised to try next? Reheat all of my joints? Try out the mod you linked earlier?

[Paul Birkeland]

A3 is supposed to be 1.5V.

70V at B1/B4/A6 is within the acceptable range.
