Tube Consoles

Postby ruffrecords » Sun Apr 05, 2009 4:19 pm

I have designed and built a number of consoles over the years, including a stint in the mid 70s when I was lucky enough to work at Neve. Now I am retired I have returned to my fist love - all tube consoles. I would love to hear from other forum members interested in designing, building, collecting and restoring tube consoles - new and old.

Cheers

Hi Ian: I found the schematic for the U.A. 610 input module on another forum. Will copy it & send you a copy as an email attachment.

Also decided to get back in the pro audio biz. Have all my sketches from my 6 input tube mike mixer for on location recording. It had no E.Q. but had a key switch for each mike pre assigning it either L., R., or center (equal split between L. & R. Very low distortion, low noise & down 1.5 d.b. 30HZ & -.5db @ 20KHZ. It used UTC A-10 mike transformers.

Hi Bill,

Did you ever send the 610 schematic?? It does not seem to have arrived.


I like the L/C/R key switch idea; easy to implement and keeps crosstalk to a minimum. I was thinking of doing L and R toggles so with both on you get centre and with both off you get channel mute. What do you think?

Cheers
