CHASM REVERB

[deadastronaut]

cheers marc...

[stallik]

Aw come on Rob, you're making us mere mortals look incompetent 

[deadastronaut]

 

[Maik]

Yes Rob, sorted it nearly.
The power supply sucks! Tried it with battery and its quiet.
Now only a little prob with the osc. But I had no time to look yesterday...

[deadastronaut]

ok cool...

having a 'pop' issue with my build...hmmmmm

the fets/mosfet switching should eliminate any noise whatsoever, that's why its there ......(as it did in my diy pcb)

i'll poke around with grounds etc today....

[Maik]

How to wire the osc switch WITH led?

[deadastronaut]

use a dpdt..

one side for switch , other side for led/s  red on/green off maybe..


_ led+.....

_  9v

_led+.....

join both - of leds to a resistor...then gnd.


or stick your resistor from 9v to middle of switch...


or do it the other way with gnd going to centre lug...with leds reversed..up to you man..

[Maik]

Thanks Rob.
I can only do paint by number...

[deadastronaut]

me too..

[Maik]

LOL

[deadastronaut]

sorted my pop issue...

swapped the fets, silent as a mouse now..back to lush verb..

[deadastronaut]

here's a drill template for the CHASM in case anyone needs/wants it to make life just that little bit easier..

Nice, what about a drill template for the delay and trem?  

Ahhh, forgot, there is no pro pcb for the delay. Perhaps some day???

[deadastronaut]

yeah, one day....

i'll sort the trem one out ...

[Maik]

Yep, I know, the delay thing was realy cheap...

[Xomby]

nice nice nice. now to make it work with btd-3h and stereo output... 

[Maik]

How much mA needs the reverb? Could 100mA go?

[samhay]

How much mA needs the reverb? Could 100mA go?

Probably. I think Rob uses a 100 mA regulator (78L05?) in his builds.

[deadastronaut]

^ yep,

[Maik]

Thanks
