Tube Mixer

[Tubetec]

Hi Ian ,
I guess it seems like theres a reasonable amount of surface area exposed to dissipate the wattage involved ,Ive certainly run into issues where fet condenser mics were troublesome due to running under ambient and condensation of the breath of the artist caused capsule leakages ,never had an issue with tube mics in this regard though.
Anyway saluts to you and Holgers triumph of Anglo/Germanic engineering ,long may it continue.

I see you have built in a Bo Hansen DI, which is cool, but what about the preamps? What design are they?

What design are they?
