I haven't checked in for a while..the last few months have been extremely busy, but now w/ the coronavirus it's suddenly eerily quiet. So in this social distancing I'm making some time to work on some of these designs.
Update on progress in past day on this board. It will now be the same size as the Gilmore Lite mk2 enclosure, and have 1 output. The power supply will be likely be +/-18V, which is about 15% higher than what is in the desktop adapter, so there will be an increase in max voltage swing of the amp. The supply will be capable of about 20W, so it will be running about 50% capacity with a Gilmore Lite mk2. Estimated price $299
As it is right now, the power supply will be on if it is plugged in. The switch controls if the output is enabled. This replicates how it works already on the Gilmore Lite / mk2 when using the power adapter. But it is possible i could still remove the switch completely, as the Gilmore Lite has an OFF/ON switch anyway.
I will also do a larger version that is 50W capable, including the USB port you're suggesting. It will have 2 or 3 DIN outputs (for powering future products or multiple Gilmore Lite mk2s), and I could also consider a set of insulated binding posts for those who want to use the supply to power their own projects, if anyone thinks that sounds interesting. Estimated price $499
