Modified m269s on ebay
« on: October 10, 2019, 07:06:59 am »

I'm not sure if it is in the scope of this forum but please could we have a discussion about these microphones:


"Factory modified with ef86 to avoid the hassle and expense of ac701k"

As an owner of an unmodified u67 and m269c I know how similar they sound. But surely this modification makes these mics into u67s?

And even though they are factory modified surely there would a be a corresponding drop in value? Or maybe these are just u67s with m269 bottom bells?

Given the "factory modified" line I would personally expect more detailed info about the power supplies and modifications (as well as pictures?)

Anyways, I am not interested in purchasing the microphones but it is an interesting discussion (at least I think)

Too little visual information to make an educated guess as to the validity of the conversion and the effect on value: no capsule, inside amp or power supply views. Also: the connectors are no longer Tuchel, but East German copies which are not compatible with Tuchels

If the mics were "factory" converted to U67, there should be Neumann-issued documentation. If not, the value drops, and the mics' intrinsic (usable) value will be your base line for pricing.

Also: always  think of the other end of any Frankenstein deal, i.e. when it's YOUR time to sell: how much explaining will you have to do?

Take all of this into consideration before you bid.
