I am looking to purchase a power supply I can use at my work bench to test out my various 6V ( or 12V ) electrical parts. I recently picked up an NOS 54-55.1 truck radio.
I am under the assumption that even being NOS, it is still very likely in need of some replacement parts that may have degraded over time. Wax capacitors and the like. That said, I'd still like to safely test it ( along with a number of other parts ) and don't want to be pulling the battery out of my truck all the time to use it for this purpose. I like having the right tool for the job.
I'm wondering if the commonly available 30 Volt / 10 amp DC power supply units that can be purchased on Amazon for around a $100 or so be appropriate for this type of application? If so, can anyone recommend a unit you might have good experience with?

Thanks in advance for any assistance.
