Anyone have a schematic or inside gut shots for the Walrus Emissary Boost?

Do you have a short (in milliseconds) mute circuit to quiet the relay switch noise?

Tayda sells the ZIF connector and banana jacks - https://www.taydaelectronics.com/zif-socket-18-pin-0-3.html & https://www.taydaelectronics.com/4mm-banana-female-socket-blue.html (plus red and green) You can hook your DCA cables to the solder lugs of the banana jacks.

Wow... it was a bad IC.... Swapped out and it works as expected now! Whodathunkit? Thanks for everyone's input!

I get my ICs from mouser or direct from Texas Instruments... could just be a bad TL072... I will swap out.

nope... I checked it... all is connected per schem.

I was asked if I would make a Greer Southland for someone.... so I check and sure as rain, we find the schematic here. I put it on the breadboard (thanks again to Robert for the trippin' breadboard) and I found the output to not go above unity even with gain and level full up. Doubled checked...

I just added the pads. I have an adapter for my Peak as well (see image). Yes, pressing it down is necessary to make solid contact. back end of a pencil with an eraser head would do it... :)

Attached are my Gerber files without logos. Note that the ZIF connector works for every 3 sockets. You can see in the traces below. I use the Banana sockets (Tayda sells them <-click link) and they have the solder connection underneath. If you do not want to cut off your hook probes, you...

Good point. In my case I have a SMD breakout device already. But.... If anyone wants one with pads... I have updated it.

also on the other bench: Diamond saw makes fast work for PCBs. I know... I know... I can have them all scored/cut at the factory but they started to charge extra... and since I have the means and am a frugal dutchman....

On the Bench today: Ever tire of the hook probes? I made up a little breakout board for my DCA75.I will make a backing board to have the DCA and the board mounted with the DCA at a tilt up for easier reading. I have the hook probes on the banana plugs so I can hook up that way too! Anyone...

On the bench today: I have this issue to solve... has a weird buzz, almost like that old cell phone close to electronics.

Oh I get it... it is a metal rack shelf 48" long, 18" deep and 72" tall. The drawer cab sits on the shelf with about 1" of space at the top.

Doesn't bind. I think linear rails would be better tho. My next build will be rails.

You are dead on the money! That is EXACTLY how I saw it and made it. The inventory is in Excel too...

Just 3/4" plywood. It's like a set of drawers if you turn it sideways. I just made it sized for the bin cabs that go inside. 3/4" ply is overkill on the "drawers" but I had a bunch of 3/4 sheets available in the wood shop and some time to kill. The next set will likely be 1/2" ply for the...

I made the cabinet - vertical drawers essentially. I ran out of wall space so I compacted. Parts are inventoried and bin numbers assigned. I will make another as I need more bins...

I see you and raise you...

What transistors were used in the original? Want to see if I have them or need to find em!
