That is correct!

It is one of the discrete I/V circuits I am working on. Specifically it is the "Counterpoint" circuit.

Cheers!

I believe that I can plan my layout such that I can replace my IVY with up to 3 new TPA modules. The SPDIF lines will be longer than I would prefer as a result, but these are the small prices we pay!

Does anyone have Buffalo DAC & TPA logos in vector format? I'd like to put those in my custom panels.

My stuff arrived today and I have just a couple of initial questions. I'm sure there will be more, but better now than after I screw something up

The IVY OPAMPs are now OPA1632 instead of THS4131?

I assume thermal paste should be used with the isolating pads?

Cheers!

No need for paste, the pads are designed to conduct heat.

The THS4131 and the OPA1632 are virtually the same chip.

Cheers!

Yes. In this application they are identical.

I assume you mean for the power supply voltage regulators. There should be a pair of thermal pads in the kit, which do not require any paste (in fact, paste will make things worse).

Like this...

You're both quick on the draw!

Just wasn't sure what material the pads were. I've used Avid ones that don't require paste, and I've also used a much cheaper brand that did recommend paste......

[EDIT] And a LCBPS lives! I always love finishing the first step
