@clengman: I am going to make the same mod on my 4TV. Very interesting topic with very useful informations.

Anyway, did you finally modify your amp? Does it work fine?

Vincenz - I sent a PM, but I remembered that I didn't end up doing the mod exactly as Nigel recommended. I think my method is equivalent though. You can see what I did with pics here:

I think you need to register an account to look at content there.

Vincenz - since you said you were having a little trouble registering on sewatt.com, here's a pic of the mod the way I did it, and what I posted on the forum:

I've attached a photo of the front of the board for reference and a photo of the back of the board that's marked up with my proposed installation. This is what I'm planning to do:
1) Remove the jumper that connects Tag 6 to the trace connecting the diodes, the first filter cap, and R16.
2) Make a cut in the trace at the white line just above the diodes.
3) Connect a jumper (red line) from R16 to "Tag 6."
This should divide what was previously one node (the diode output/OT input trace) into two separate nodes for B+ OUT and B+ IN as I have them marked in my photo. It also leaves two vacant holes in the PCB that can be used to solder in the VVR.




It's working fine.
