The EQA-10 was probably the first mainstream equalizer I remember due to its' $100 list price giving it wide acceptance in the market. I think I purchased mine new in 1981 or 1982. The spectrum analyzer was a nice touch for night viewing and I suppose had some legitimate use for visually referencing the EQ curve. Back in those days, we'd record albums to cassette for use in car audio systems, and having the ability to pre-equalize cassette tapes to punch up both the bass and high-end made a world of difference when listening in the car. When running in home audio mode though, I usually minimized or outright bypassed the EQ settings as it would introduce some audible (although very slight) distortion into the music. For those with smaller home speakers, I'm sure this unit did provide some usable tone control. Though I generally applaud all TEAC products, particularly their cassette decks, this particular unit was of marginal quality...push switches that would occasionally 'pop' loudly through the speakers when engaged or disengaged, and a color display with a dimmer secondary ghosted image that developed after a period of months. Still, these units did serve a purpose back in their day, when analog albums did not offer the bass response we're all accustomed to today.

re: EQA-10

I just bought one through shopgoodwill.com. Only $21 in, and the dang spectrum display won't work. What is equally maddening when the unit is powered up/down, and tape loop buttons, eq on/off buttons are all pressed, the internal static causes the LEDs to display and randomly jump. But no music signal will cause the LEDs to illuminate. Piece of junk???
