Mods for the 205
- OktavaMod
Michael Joly’s “standard” mod for long-geometry Chinese ribbon mics removes mechanical filters and adds acoustical damping, resulting in improved LF and HF extension, better HF detail, and reduced mechanical resonance. The “premium” mod includes retensioning of the ribbon and a Lundahl transformer. - Marik
Marik offers repair and modification services for all types of ribbon mics, vintage and modern. Ribbons can be retensioned or replaced. Magnets can be upgraded. Transformers can be replaced with Marik's custom low-noise toriodal design.

Description
The Apex 205 is the best-known retail version of Alctron’s HRM-8B, a large-format ribbon design that has, according to Oktavamod’s Michael Joly, “obvious internal resemblance to the AEA R84.” The same ribbon motor design can be found in the Nady RSM-2 and the Shinybox 46 (the latter being remarkable in that it has all the mods you’d want to do built in from the vendor).
Common mods for these mics include:
- Re-tensioning sagging ribbons
- Removing blast filters from behind grille
- Swapping the stack transformer for a Cinemag (e.g. CM-9888) or Lundahl (e.g. LL2911) or Edcor (e.g. RMX1)
The Apex Electronics 205 is also known as: Apex205.
