Title: True Grit (Kit) not working
Post by: guenter1910 on July 01, 2026, 05:23:50 PM

Hi all,
I just finished the assembling of the true grit and unfortunately it is not working. The only thing that is working is the IN switch and the Blend Poti. All other switches and Potis have no function. I could measure the + and - 16 V on V+and V-. Also the tube is heating up.

Since I have not found any troubleshooting infos, I do hope to get support in the forum.

Any help is highly appreciated!!

Thank you in advance,
Guenter

I measured my way through the circuitry and discovered a broken link between C13 and R12. After fixing this everything seems to work fine. 

All the best
Guenter
