Faulty TL Audio 2011 - Need help!
« on: July 29, 2019, 04:09:45 PM »
Hey guys,

my TLA 2011 Tube EQ is acting up - here´s what´s happening:

- When bypassed, the signal passes through the unit flawlessly.

- When the EQ is switched in, a loud buzzing noise is audible (the input signal can be heard very, very faintly). This noise is only audible when feeding the line inputs a signal. Without any input no noise is present.

It´s important to know that the tube section is only active when the EQ is switched in!

Do you guys have any idea what to look for?

What I´ve done so far (without luck unfortunately):

- Change the tubes
- Change the ribbon cables between the PCBs
- Inspect for broken solder joints

Sample of the buzzing noise: http://www.data.soulone.de/tla2011_buzz.mp3

Thanks,
Eno

Check the power supply and confirm it is correct.

I know switches and trimmers can get pretty janky ....

Maybe try chop sticking/tapping around in some areas too???

Thanks for the replies guys.

The EQ is up and running again. The issues came from a cracked PCB.
