UPDATE: I ordered a new JA Circuit Board for approrx $160(Part# WU494900)and had it sent overnight.  It arrived today and it took me about 20 minutes to swap into my XF8.  PROBLEM SOLVED! Everything is working great now.  My original hunch was correct after reading other threads that the muting transistors were leaking.  I plan to replace the transistors on the board I took out so that I will have a back up in case this happens again.  Super easy fix, thank you Motifator Forum and thank you 5pinDIN!

Hi. I have this problem too (XF6)…
Bleeding in the AS-L, as-R - no bleeding.
Where did you ordered JA Circuit Board Part # WU494900?

Thank you.

I wrote this article to tell my personal experience about this breakdown that I also met with the First Motif.

You can fix it for less than $ 10

Hello, stefpiano! Excellent article!
I found out that my XF6 has a problem with three transistors out of four. I bought Toshiba 2SC3326 in the online store. The cost of one is 17 rubles ($ 0.29). This is not comparable to the cost of the WU494900 board ... My buddy an experienced microelectronics specialist will help me to replace these transistors.

Where did you find them on the online store?  I tried looking for them with no luck.

Hello!
I ordered in Russia. I do not know if they have delivery to other countries.
