Supposed to be a V72 I guess   |

572 Red Stripe is a mic/instrument preamp designed in the 500 standard. The module is transformer balanced on input and output using Sowter and Edcor transformers. All regulators on the front panel are stepped switches. Excellent for recording any sources, including line signals from microphones, instruments like guitars or keyboards (Hi-Z input at the front of the unit).
What is it for?
This is an excellent preamplifier, that can be used with a variety of sources: line signals, guitar pickups (via Hi-Z input), dynamic, condenser and ribbon microphones. It always provides outstanding results. With one knob gain control (41-stepped) you can push it nicely, but still make sure that you don't overload the next stage of your signal chain. The second stage overloading gives some sweet harmonics vibe. HiZ input is accessible from the front of unit. Handy!
IGS 572 Red Stripe, single channel, pure tube mic preamp in a 500 module, two double-triodes (JJ ECC803S and JJ ECC82), UK made input and American output transformers, -20 dB Pad, polarity control, +48V phantom power, low-cut filter, DI-Input 1/4" TS Jack 1MOhm, max. Input Level: +16 dBu, max. Output Level: +28 dBu, back-lighted analog VU-Meter, +48 and clip LED, Made in Europe.

I really liked their prototype that had the solid grey faceplate better than this one.
I designed one and could barely get it to fit in a 2U 500 unit, but I was going with Sowters I/O trannies and their plate choke too.
This is one I'd really love to take on a test drive on a wide variety of sources to see what they were able to do.

How would this differ to my BAE 1073D, Millennia STT-1 (valve and solid state paths) and API 512C?
In was kinda thinking i had the pre-amp department covered - but there always seens to be one more to consider :-)

The performance of this unit is going to be EXTREMELY dependent on the 500 chassis it is mounted into, due to greater amperage requirements than your average 500 series pre. It has two glass bottles that need lots of juice!! It's not just the voltage, and of course beyond just voltage starvation issues, but actual amperage requirements.
Nothing sounds fuzzier than starved electron bottles!
