Do you have a larger pic which includes the full length of the leads.
PS: and the reverse of the board.
Above is a 1985 Ernie Ball 2EQ Sting Ray preamp.
Your preamp is also a 1985. Note the 3 grey and 2 blue electrolytic capacitors. Putting aside capacitor colours, it's the same as a Pre-EB preamp from c.1982 onwards. EB and Pre-EB use the same circuit boards which are designated "B3" on the underside copper track. The only difference between EB and Pre-EB is that EB soldered the IC chip "LM4250CN" direct to the circuit board. The Pre-EB has the IC mounted to the board via an IC socket.
Before soldering the preamp into circuit it should really have a 1K Ohm protection resistor added to the end of the white lead-out wire (bottom right). EB included this resistor on the board in c.1986.I have the wiring schematic if you need it.

How likely is the preamp to blow without it anyways?

Travis is that you?
I bought one identical to that from a guy named Travis lol
Any chance you wanna sell that one?
