Seoul P4 in a KL4...can it be done?

[KDOG3]

I thought I saw a thread in here where someone had done it. Does anyone know if it will run on primaries or just the 3.7 rechargeables?

I'd guess that it'd remain (circuitwise) the same - you can run it on a single rechargeable or two primaries. Two rechargeable will fry the circuit.
