G.TEN 500 series graphic eq (V4 revision) 18.05.23 back in stock

Hello,
Is there a Mouser order number for the bypass switch? I almost finished my second unit, but I can't find the switch anywhere. Must have misplaced it somewhere.

This e-switch should work. https://www.mouser.com/ProductDetail/E-Switch/PBH4UEENAGX?qs=5gBG3L055oMixeQf4bmFww==

Any way to be notified if/when there are restocks on these kits? Any chance of a bare PCB/Panel option in the meantime?

 

[xssory]

anyone seen an update on availability for these?

Hi folk!
We are pleased to announce that the new batch of G.TEN is ready for shipment.
Available here:
Equalizers
G.TEN V4 is the fourth reissue.
In this revision we tried to take into account all the nuances and requests of those who bought and assembled the device earlier, as well as our own ideas for its improvement. Couple resistors was changes for more common values, pcb layout was optimised a little as well as output transformer connection was changed. Schematicly V4 is the same as V3.


Cheers,
Igor

Hi, just finished one of my V4 units - everything seems to be working except I'm getting a -6 or so db drop in signal even with the unit bypassed and a -1 db drop with the unit engaged (sine wave at 1k). Any idea what could be causing the level discrepancy?

Thanks,

Ryan

Also I was curious if there's a resistor that defines the brightness of the indicator LED- mine is very bright compared to my other 500 series units next to it and it would be great to dim it down a bit

Thanks,

Ryan

Hi, please disregard the levels question - I think it was something funky to do with channel linking switches on my 500 series rack - I seem to have fixed it. Still interested in LED bringhness adjustment though if possible

Are these coming back on stock? Ty!

Hi Igor,

I sent an email but wasn't sure if you prefer a post here in case this helps others. I just ordered 2 x G ten units V4. I had two Capi 2503 output transformers which have more leads than the new G ten PCB has available.

There 2503 has Brown, orange red , purple blue, green and yellow and grey

I’m wondering how I should solder these in?

Thanks!

 

[Bobby Baird]

Yes, curious about this as well. Looks like the brown primary is being used, but the secondary blue, yellow, violet? What should be done with other leads?

Are the g.ten kits available again? They're still marked as sold out on the site.

 

[paullambert]

Yes, curious about this as well. Looks like the brown primary is being used, but the secondary blue, yellow, violet? What should be done with other leads?

Here is the answer I got for the capi 2503
In order to get the correct trx wiring you need:
connect VIO + GRN together and connect VIO to board pin
connect BLU + GRY together and connect BLU to board pin
connect RED + ORG and isolate them
connect BRN wire to board pin
connect YEL wire to board

Will these be available in the near future?

Hi everyone,

I've just finish my G.Ten. Everything works exept i have a level difference when the unit is on. This is not a drop but a bump, a pretty big bump (around 5db maybe). As stated int he assembly guide in that case i have to check the resistors which i did and it seems there's no mitaskes so if someone has any idea for help he's welcome.

Cheers.
Ludovic.

Hi Ludovic!
There is only one reason why the levels may not converge, and that is the cascade gains. Gains are set by the values of the resistors around opamps. Therefore, check the resistors again.
Check Appendix, page 54 of the assemble manual. There you can find the exact signal levels that should be along the signal path.
Another possible reason may be the connection of a transformer.
Keep me posted.

Hi Igor! Thanks for the help!

To make it short now it works all fine!

So i've checked once more all the resistors which were all good then i follow the testing of the appendix and things were wrong with U2, i had 0,49VAC everywhere so i decided to replace the opamp (i had one in stock) and it shows the same measures so i replaced the one that come with the kit. After that i reconnected the ribbon cable (that i've disconnected to see if the soldering points were good at the pcb's back) and it seems to work. So i'v tested again pin 3 and 5 of U2 and the measures were right! It seems something happened with the 5532, i don't know what.

I have one more question, the red light is slightly bothering me, is this possible to cut the red lead of the led and only have the green light for when it is engaged?

Cheers.
Ludovic.

Hi,
Are kirs available please?
Thanks

Glad that now it works correct. Congrats!

Yes, you can simply unsolder red leg of the led and leave it in the air.
