As I have said from the beginning I will mot publish the schematic yet.

I do not want it to be copied right away.

Cheers!

Ok. Let me then ask: how to disable the whole output stage and take the signal directly from ESS chip? I've tried that by removing IC9 and IC12, but failed...

Are you still planning to copy it yourself as an update to the current stand-alone IVY? While I cannot afford the B32, I would love to try the IVY 2 with my existing Buffalo......

Yes. In fact I plan on having that in the next batch of boards I order.

Cheers!

Hi,

I don't mean this badly, but this has been said a hundred times. The Buffalo32S board is not designed to be used in that way. I don't have time to support such modifications.

This is why it is a finished module, not a kit or bare PCB.

There will be a board without output stage I suggest anyone who wants to design an output stage use that board when it is available.

Cheers!

About two to three weeks. That should give me about 2 days to come up for a breath.

Brian deserves a lot of credit as TPA would not exist without him. I know I am very grateful for for his dedication.

Absolutely, my apologies Brian. I was just excited about how it sounded.

Both you guys are the best and I can't believe how much work you put into making these kits.

Hey folks,

New placid adjustable shunt regulating power supply boards have been ordered for testing. I should have them in a couple of weeks.

I will let you know how it goes.

Cheers!

Hi Russ,

Is the board big enough for boutique cap like Nichicon Muse?

Cheers,

Yes I believe they would fit. I gave something like 12-13mm around the big caps. 5mm pitch.

Is that really a big issue to advise for instance "remove all opamps" (my guess) ? Should I feel myself as 2nd category customer not allowed to touch anything since my taste differs from what most of users report?
