Babelfish XA252 / Babelfish XA252 SIT / Babelfish XA252 SET

:spin:

for all previous gens of pcb, problem solver is additional resistor in parallel to optodiode and changing BD follower pair to pair of more sturdy ones

one of the Boyz already did it (just starting morning coffee, bare with me) but I can't remember which type

I bought quantity of TTA004B/TTC004B for all future kits
Again some evidence these mods make it a much more robust amp; was not putting attention to my clipping indicator and drove the amp’s that hard into clipping that it triggered my DC offset protection. Notice that I have 38,5V rails! Both monoblocks together went into protection mode and played nicely further when lowering the volume.
 
Boards restored and cleaned up, 3 smd parts resoldered - back in business 😀
Now I just would need a current schematic for puck only and SET version.
