The Oktava MC-219 and MK-319 are prized as fairly inexpensive alternatives to cheap, poor quality Chinese large diaphragm condensers. Unfortunately the MK-219 and MK-319 are plagued with body resonance and grill resonance problems respectively, aside from some issues with the electronics. The mod addresses each of these issues, dampening case resonance while reducing load on the capsule and the transformer’s load on the FET stage.

Full instructions for the mod are included in Scott Dorsey’s Article for Recording Magazine.
