Collection of mods for Beresford TC-7520

[HighFidelityGuy]

Thank you for the fastest reply ever!

I thought it was a 220PF?? No?

No probs.

If you're talking about the little red caps for the headphone stage that Stan said helped some high end headphones, then the ones I linked to should be correct. I had the link saved from when I did a group buy and I triple checked that I was ordering the right things back then.

Yes, you are correct! Thanks again

As I live in the states Stan, do you ship abroad?

Fran - as you live much closer to Parts Connexion in Canada, I suggest you get the Nichicons from them. It was me who used them and they're very good.

Thanks for the tip Martin. I already have the Nichicon caps you suggested coming in as samples from another supplier

Step 1 has been completed!

Have to say, the Wolfson DAC makes a HUGE difference all on its own in my otherwise unmodified TC-7520!

[StanleyB]

There have been a lot of request for a mod to change the default input selection on the TC-7520 and Caiman. The following mod works on all my DACs. I used a Caiman PCB as reference, but the layout of the area is the same for the Caiman etc.

So let's start .

First unscrew the USB PCB. It's two screws at the back of the case.

Next, look for C13 in the top righthand corner and just underneath the USB PCB.

[StanleyB]

Desolder C13.

Get hold of a 100nF ceramic cap of say 63V. It has to be a small cap!!! If it is bigger than the one in the picture, don't fit it.

[StanleyB]

If you want the TOSLINK input as default, fit the new cap in the position indicated. Press the cap down as far as you can, but make sure it does not touch anything other than the two soldering contact point at its end.

[StanleyB]

Confirm that it is not touching anything by using a small screwdriver or a needle. Run the needle along the bottom of the leads and the cap to make sure you are not getting any resistance from where the cap might be touching something.
