Finally getting around to drawing a MXL-770 footprint board. Same dimensions as the 990 but with external pad and filter switches. The transformer will be on a daughter board on standoffs. Was able to fit the internal pattern switch too! Same BFM (Big F'n Microphone) circuit based on the KM84.

MXL5000. I drew a PCB for this footprint and I'm really liking these for rebuilds. Transformer Coupled, with pad and filter switches
