What is this circuit element?

Thanks for all your help. Just to close out the thread, I thought I would post what I finally did.

I tried bypassing all the output circuitry, in other words, op amp output through a single PP cap straight out. Difference was negligible.

I then added the Toslink output. I did wind up mucking around with the circuit a bit, but I am not completely sure if it was a connection mistake or the current FO TX requires different supporting components. I used 330R resistors and both 0.1 uF and 18 pF caps and it works regardless. As I mentioned above, the part to buy is Sharp GP1FA514TZ.

The bass is great! It is so amazing to not have my sub plate amp go into sleep mode when I watch TV!

As for coax output, I was satisfied with performance from the FO, so I just switched my DVD to coax from FO cabling so that I could connect everything into the smallish number of inputs in my receiver.

I'm looking to buy a few Sharp GP1FA514TZ FO transmitters. anyone know who sells these?

Thanks

I'm having a "discussion" with a friend about the modifying a 3100 for the optical output. Here is the question:

Will the 3100 output Dolby 5.1 (AC3) when there is program material encoded in 5.1? If not, what format would be output? Dolby 2.0? ProLogic?

Thanks

No, no, and no, in that order. It is just a 2 channel stereo PCM output.
