36 VDC 9.7A 350W Regulated Switching Power Supply
Hi! I am using this with the 4x100W TDA7498 Class-D Amplifier Board. The AC power plug/wire that comes with the unit is the wrong size for the power jack on the board (Power input jack: 2.5 x 5.5 mm, center-positive -~radioshack size "O"). Advice/link??
finally found the components at a different radioshack. Had to solder my own wires to the size N (I think it was at least) barrel connector to create a power cable that fits with the TCA7498. Works great!

Ok, please forgive my ignorance. I'm just trying to figure out whether I need multiple power supplies, or whether I can use a single power supply with step up/step down converters for each device being powered?

Could these power supplies be used to power multiple devices housed in one chassis? For example: an amp, a raspberry pi/DAC combo, source selection relays with rotary control, and possibly an RIAA phono preamp? All require different voltages.
Unfortunately this supply will only power devices with the same voltage requirement. A voltage regulator will be required for items with lower power input.

This power supply has voltage tags but want a bit more info...
I assume L=line N=neutral but supplied plug does not have a wider neutral plug and narrow hot plug nor does it have a ground. Does input AC voltage need to be polarity correct?Does unit need grounding?Also, I see V+ and V-, is voltage the same along all three taps? Can this unit power more than one amp?Thanks !
AC input on this amplifier is not polarized. This has multiple powered outputs for more than one device.

I am making a amplifier with a few of the Class D boards and I will need one or two of these power supplies. Can I power more than one power supply off of one 120V line in or do I need to have a 120V line in for every power supply? Thanks.
You can wire two power supply 120 V inputs in parallel, with three separate jumpers: ground to ground, neutral to neutral, and hot to hot. But you would need a heaver gauge power cord, at least a 14 gauge. Do not wire the +36 volt power supply outputs together. Consider using a fuse on the power cord for your project.
