    Find in-line fuse holders at Digikey or Mouser. I strongly suggest one that has UL / CSA etc. listings and is rated for 250Vac.

    Thanks dude. I finally found mention of the in-line fuse being important to protect from risk of fire in the Acopian instruction manuals. I have some time delay fuses of appropriate ratings on the way for two different power supplies (and fuse holders).

    I grabbed two seemingly-good deals on eBay for a narrow profile and normal size gold box (both A series) linear PSU on the way.

    I'll stop polluting the MCTH measurement thread now!

    Thanks for all the testing atomicbob. I just picked up the Acopian A28MT300 and wired it all up to power the MCTH and run a 6C8G. I put my meter on it though and its putting out 28.84v. I turned the voltage adj screw on the lower right front and it made no difference all the way counterclockwise and clockwise. In fact I watched the meter for a while and the voltage actually climbed up to 28.98v and settled out there. Not really sure almost 29v is good for the MCTH but I'm no expert.
