tonedude Stereo set PAID SHIPPED

skeeler87 Stereo set PAID

kante1603 Stereo set PAID SHIPPED

rainton Stereo Set PAID SHIPPED

--------------------

Finished and tested.Working good.I won't build full kit.I'm sure that it's working.

Only one error.Gain pot pins reversed but easy to fix issue.

I have 5 stereo set.

Gain Fix

Cut traces and wire them.



WIRING



PLEASE READ SCHEMATIC WHEN BUILD AND SEE SOCKET'S + - AND GND PINS.

how about some screw holes for secure mounting? also caps for ic power rails would be nice to be on the pcb. what opamps you plan to use? hmm, i'd like to build this eq at some point.

more ideas to chew on
there is very much wiring... is there a possibility to arrange  the i/o pads next to each other? or maybe run io and power "bus" traces at the backend of the pcb so one could use simple jumpers between the pcbs to daisy chain them? in which case you could manufacture one big pcb and have cut lines between modules. one could then use the whole pcb without much wiring, or snap modules apart and use what ever needed;)

I added to filter board but not band boards.Easy to add.And to get more room i removed power rail caps.It's easy to place caps under PCB.

Your idea are better but i'm looking for cheap solution.Back board is extra money.Using some wires with molex connector is cheap and easy.

And making too small boards without back board is good for casing.Even you can push them to 500 series.

[tmuikku]

yeah no separate bus board, but trace the buses to the sides of the filter board adjacent to next filter board

[skeeler87]

Cool!

How much will boards be?

[ForthMonkey]

€30 for mono channel.

1 x FILTER & I/O Board
4xBAND Board

By the way i added front panel design.

This week i will order PCBs.

[tmuikku]

aha! now that i see your frontpanel i understand your decisions. the pcbs are angled to save front pabel real estate

[ForthMonkey]

Boards will be placed angled cause i have to fit stereo unit to 1U case.Boards are really small.IF i put only one unit into 1U,there will be lot of room but not usable.Placing like this is better.

[skeeler87]

I'm in for two sets please!

[ForthMonkey]

I'm in for two sets please!

I added you to the list.I ordered PCBs.It will take 3 weeks to make it work.Then i will send PCBs.

Thanks.

[Winetree]

I'm in for 2 sets.

I'm in for 2 sets.

Added to list.

Thanks.

[ForthMonkey]

Added BOMs.

[kambo]

u got schematic for this?

[fragletrollet]

Interesting project. What pots are these made for (not listed in BOM?)?

Sorry.I updated BOMs.Now you can find POTs.

u got schematic for this?

Added schematics.

[fragletrollet]

KB= lin & KC = log?

Footprint made for any specific brand/model?

[ForthMonkey]

KB= lin & KC = log?

Footprint made for any specific brand/model?

KB = Lin
KC = RevLog

Any 16 mm pot could be good.I'll use Alpha.

And what power should this thing be fed?

[ForthMonkey]

And what power should this thing be fed?

+/-15V is good for this project.
