EAB Geiling V65c vintage tube mixer | refurbished

eab Geiling V65c tube mixing console from 1954 - now refurbished

We initially offered this console as defective, but have now restored and fully overhauled it through meticulous detailed work. The input transformers were faulty and have been replaced with vintage NOS 1:15 transformers in professional broadcast quality. To preserve originality, they were mounted inside the original Mu-metal housings. From the outside, nothing is noticeable and hardly anyone would detect it – however, we do not wish to conceal this modification. Technically and sonically, the performance has not deteriorated but rather improved. All electrolytic capacitors were replaced, all faults repaired. Only the oscillator was not put back into operation, as 99% of potential buyers would never use it anyway.

The portable V65 mixing console (Übertragungsverstärker) was introduced in 1950. Later developments included the V65a (1952), V65b (1954), and V65c (1956). Even in the mid-1980s, EAB Geiling continued manufacturing tone-mixing systems in rod technology for ARD-ZDF. The V65c is a portable 6-channel studio mixer with master level control and modulation meter, built in solid tube technology. Output level options: 6, 12, or 15 dBu. Built-in test tone generator and interval signal generator. Power supply can also be battery-operated independently of the mains.

The six microphone inputs feature switchable 0dB/20dB input attenuation and provide a total gain of over 80dB ±2dB when routed to the master sum.

In a modern studio environment, this 6:1 mono mixer can serve as a very high-quality and exceptionally good-sounding microphone preamp. Depending on whether one takes the signal directly from the channel or via the master bus, the sound character changes. Each channel uses one EF86 tube. Thanks to the 0/20dB input switching, both dynamic and condenser microphones can be connected. The six channels then feed into a main amplifier built in three stages (3x EF86). Between the first and second stage sits the linear fader as master level control. The second and third tube stages amplify the signal using voltage feedback. Behind the output transformer, the signal sits at +12dB. An additional downstream transformer distributes the output and adapts it to +6dB, +12dB, or +15dB.
