For sale

I have managed to get some rare discrete SCHLUMBERGER filters, EQs with Inductors, Parametric EQs and Pre Amps from France.

They were all made for the ORTF, the French BBC, back in the 70s, amazing quality, reliable, broadcast, obviously built to last forever, just like NEVE or TELEFUNKEN equipment, it's the same kind of standard.

Please only contact me if you are serious about it, I can supply them in custom built rack if required.

70s one band discrete EQ with inductors, like Neve or Neumann (ELMA switches everywhere...)

Clever 70s discrete Mic Pre cassettes with optional EQ and filter configuration, It's the old concept of the Fader just next to the Mic-Pre Level, like some rare Langevin, Electrodyne and Quad stuff...

Top quality discrete Line Amps, full of transformers, built like a Rolls Royce, amazing! +44V single ended electronic!
"Built in" power supply and transformer for each module, just like the valve Telefunken! Also big UTC type transformer on the output stage...
I can modify these to your needs at an extra cost, Mic pres, summing Amps, Line Amps etc.

I also sale the modified Dolby units with the "POM Mod" on the "A" card, which is a full band (vicious) limiter. I can do the 70s high frequency mod too if you like. It's pretty much: "one box, one sound", all discrete and transformers in and out:
