Just finished two weeks ago. This one only has tape head inputs. IEC, NAB and AES(30 ips) eq..

Nice. What are the controls on the output box? Three for each channel I see.
Looks to be Gain, HF and LF. Glad Charles added LF to tame the excessive head bumps on some heads including Studer - something I had been suggesting for from the beginning.
So Manley Tube Tape Head Preamp and above K/C model have LF adjustments.
Thanks Bruce.
Can you give me a quick reply of what I'm looking at (red and blue lines represent) in the frequency response graph? Left and right channel? Head output? Line output from tape pre? or something else?

Per a lot of trial and error, I've found a single "suitable" resistance value that seems to work with most of the heads I've experienced and put this fixed value in all my "standard" preamps. Otherwise, nothing new.

Hey Guys,
Let's not make "a crevasse out of a head bump", and scare people away. The result, when listening, can actually be very small. As you increase the LF "dampening", the resonance peaks are tamed, but too much and the lowest frequencies start rolling off.
Compromise time.
And the main "bump" depending on where it is - in conjunction with the music on the tape - and the speakers/room - can actually be "quite euphonic".
I've mentioned to a few folks that, "I never met a headbump I didn't like"!

Ki,
Didn't take (or send Rich) a pic of the "backside". Just a cable to a (second) jack on the pre, where it gets it's power and signal, and two RCA's for the auxiliary (switched) input.
