t-amp output schematic

I took off inductors & cap off board to try mapping the schematic, this is what I came up with. Sorry I don't have schematic drawing program.
Only one channel is drawn (too much effort using paint prog to draw other)

Roughly same schematic as tripath eval board (I know I have left out final cap after zobel network) but

My questions are:
1. instead of single ouput cap of 0.47uF to ground t-amp has 2 caps to ground from OUTP1 & OUTM1 caps C19, C21 & C14,C22 - Does anybody know the value of these caps?

2. t-amp circuit has additional cap from OUTP1 circuit to ground cap C13 - does anybody know value of this and its function?(same on other channel)?

3. Can zobel network be left out? Has anybody tried this?

oops forgot to attach schematic

bump

Has anybody tried to bypass output circuit of t-amp by removing on-board inductors and connecting air-cored inductors to output diode and then own output circuit with caps to ground and zobel network if necessary?

Signal after output inductors no longer contains high freq waveforms, so tight circuit with smd parts not necessary

This would allow experimenting with different quality & value caps as well as eliminating zobel.
