[Amps] purpose of 3 ohm resisters between base and emitter?

Parasitic oscillations is a valid guess, and better than to just load
both sides of the sine-wave drive. Biasing could be another valid guess.

All, I have an ENI power amp with what look like SD 1726 transistors in
a class C configuration. The circuit is pretty standard, however there
are 3 ohm resistors between the base and the emitters. Can some
speculate on the purpose of such a low value? It is common for resistors
to be used in this configuration however they are usually a larger value.
Thanks for your thoughts on this - Dan kb0qil
