Apex 435 mods?

Henchman · 24th December 2006, 01:29 AM

Ok, so I've ordered a cheap Apex 435 mic.
What can I mod to improve the soundquality?
Yes, I'm handy with a soldeting Iron.
No, i don't want to stick a $400,- diaphragm in it.

- Capsule: get a CEK-89 from Peluso
- capacitors: quality caps.
- Remove a ply of mesh on the grill (major improvement)
- Paint job

Mark,
Have you done the mod yet? I am very interested. D. Thomas implied that you could mod a 435 to more closely match a U87's sound than the 460.

I ended up pickign up the CAD M177 instead.
I have emailed Dave Thomas abotu a mod for that though, and am waiting for a response.

Use a Siliconix J305 fet. Use Hitachi 2sa1084/2sc2545 bipolar transistors. Use MIT poly film caps. Rework the oscillator to increase sensitivity and to gain s/n.

Is that for the CAD m177?

Never seen one. This is for AKG, Neumann, Sennheiser, Schoeps, Milab, Marshall, SE, MXL, etc.
