I tried hounding Toshiba for this datasheet and also the TA7214P which is
the dual amp version. Basically I was passed from division to division
to supplier to division, till finally some Toshiba person recommended
I ring Email Electronics, which was where I was ringing from !!

I gave up in disgust ! Even the service personnel seemed to have difficulty
comprehending what a datasheet was !

I have the "hand traced" circuit I made from the Clarion car deck where the
205P is used, and from that I could work out what most of the pins were.
The TA7205P is supposedly 7.5W. It requires external compensation, bootstrap
capacitor, output coupling capcaitor (delete in a bridge circuit), output
stablisation capacitor, input coupling cap and feedback components. I'm
not sure what the capacitor beween the + rail and the pin next to the 
+ rail was for ? (If you ever find out Please let me know).

Sorry to inflict this tale of woe on you, hope you fare better !
