Where to get GNSC mod CD player repaired

I would send it to Wadia. I don't see why they would not replace the transport if this is what is defective. I would call Wadia.
Good luck.

Hi Everyone,

Steve no longer does any repairs or support of GNSC modded units. That business closed and Steve is not able to make himself available for support and repairs. When GNSC closed, he did provide a link to some technicians he recommended for repairs though. Hope this is helpful:

Really a shame that GNSC went out of business. They did some great stuff. I have several pieces and have enjoyed them very much.

Before Steve closed shop, he left a post on his site. He left the name of 3 techs.

You should definitely contact Wadia first.

thank you all very much, I did call Wadia 3 times and left voice mail, no one replied so far.

I will try the True Sound first and later post the result.
