Anyone familiar w/ this goliath? Made in late-80s/early-90s. It's a 3U space 4-band stereo (dual mono or link-able stereo) parametric, but I can't find any specs about it on the web. I know Ashly was an early pioneer of parametric EQ. Is this sucker tube? Transformer? Gerbil on a wheel (it's big enough to house a whole family of wheel-running rodents)?
