I sold the last kit from the latest build six months back. I do not market it aggressively so sales are slow.

My current issue is that I ran out of circuit boards and have to order more, along with sourcing components. Covid and sanctions on China disrupted the supply chain (also made my last 2 component orders difficult and expensive).

I can’t get the quality of circuit boards I need and the price has gone up 5x plus we have to pay a 25% tariff on top of this for orders from China.

The worldwide shortage of chips/components is serious for all makers and for me has got to the point where critical items like the DAC used are no longer available.

I created a board design using newer components but those components are also in short supply. It is going to take a while to resolve this as I can’t source the quality and price I need to make it viable at the current price.
