Garash G.TEN - ten band graphic equalizer in 500 series format.
G.TEN is a 500 series format ten-band graphic equalizer. It’s a great sounding and easy to set EQ with all the important musical frequency points.
 It’s great for shaping drums, guitars or any other sources where you need a great sound and fast setup.

Schematic was LTspice emulated and carefully tuned. The EQ is based on an IC gyrator filter which mimics an inductor. The G.TEN has proportional-Q (wider Q on low boost/cut and narrower Q on high boost/cut). This style of EQ became popular in the mid 70s when the famous console module was invented by Al Davis. G.TEN is input balanced and output balanced. Output buffer is implemented on 2520 DOA that boost output transformer. G.TEN has true relay bypass with a led status indicator.

Hi Igor,

Hi,
I did not post price here as that's not a white/blck market. I think it's correct.

G.TEN received! One question. I will be using the B output option with 2520 & 2503 output transformer. I noticed that there were 2 - .1uf ceramic capacitors above the dip8 that 1246 socket. I believe the build manual says to leave these off board. Just want to confirm that I should remove them, or if it is ok to leave in circuit? Below is picture with circled components in question.
Thanks again Igor!

Hi! Congrats!
In a such configuration you should install 0.1u near 1246 and do not install them near 1646. Like it showed on page 27 (I've added additional image, see attached).
One more comment - on page 43 there is a schematic for wiring 2503 as 1:2. There is a mistake - that's necessary to ground only one unused wire (ORG or YEL), NOT both. If you will connect both you will get a short circuit at one secondary (that's safe for transformer) and you will read -6db instead of +6dB trx gain.

Sounds awesome! Ruler flat engaged. Looking forward to getting a couple more to sit on snare and bass drum tracks.
