WTDI issue ?
« on: April 18, 2019, 05:17:42 AM »

Hello there !

Feel free to move my topic if I'm in the wrong section..

I'm struggling with my WTDI which is malfunctioning. I can turn it on, the blue led is on but I'm getting no signal at all. I then decided to open it up and try to figure out whether I could see any burnt component or blown-up capacitors with no success so far.
Before I throw it away, I wondered if you guys would have some clues or ideas to test/check..



I thank you a lot !

V.

Hi Bassmann !

Thank you for your reply :)

Yes, weirdly, jacks are deep-plugged in, leaving a little gap between the connector and the embase of the jacks..
Actually, when I switch off the bypass (red light is then off and the preamp is on) I can hear a very low signal lost in the hum when I turn the gain knob all the way up..  I can also notice tone change when I fiddle with the eq knobs, but that's all..
It sounds like a preamp chip has died but I can't see anything on the pcb.. :/

Could be a problem with the Gain pot or the first OP amp.
I would change them first.
