What is the age of my Wurlitzer piano serial number 192157?

Free Piano Age Research Look here. It looks like it was built between 1939 and 1940. Go down the page til you find Wurlitzer; after 1937: The year built is found by finding the serial number 192157, which would be between 180000 and 195000. That would make it having been built between 1939 and 1940. Hopefully, that's correct.

What caused my wurlitzer model no. 625 to stop playing after removing the ear phone plug I had inserted? I get electric static when turned on so I know it's getting electricity.

Well if the removing the earphone plug and the unit no longer working aren't a co-incidence? Then perhaps the earphone socket has faulted and cut off the speakers, output. You see in an earphone socket there is an additional set of contacts, that makes & breaks the line to the speaker and routes it to the earphones, often these contacts will stay open, after the plug is withdrawn. and thus stop any output from going to the speakers. Or sometimes the solder join on the PCB can break and the effect is the same.
The only way to tell is to examine the unit and check this out. As mooted before though, i do wonder if this isn't a co-incidence, and the fault is to do with something else, often these units fail in the area of the output amplifier IC's. The unit really needs to be put through the troubleshooting procedures to exactly tell. If one was to attempt a DIY, then at the least one would need to obtain a service manual, for these steps and to obtain the parts numbers to buy any spare parts.
Above is a place to assist you with a service manual, should you wish to DIY? However, Wurlitzer's are a complex device, and my professional recommendation is to get a "Quote" for any prospective repairs, from a Wurlitzer repairer.

I am attempting to repair a Kustom K100A-1 guitar amp. I found one shorted output transistor, an RCA 36892, which crosses with a NTE 130. Do I need to replace all 5 outputs with matched transistors, or can...

I don't have a schematic for this unit, however good design would not demand matched transistors.
If a transistor has shorted, USUALLY mating transistors have been damaged. I am not sure how "5" outputs are configured as usually there is symetry and an even number. If the "5" are all on one side and there are mating trnsistors of another number, then likely there is damage to more components and probably back one stage in the drivers or even farther.
Hint: when re-powering this after repair, put a 100 Watt light bulb in series with the power into the unit to act as a limiting fuse that resets without driving heavy current into the unit causing more damage due to failed parts that were not eliminated in the first reapir.
