Sure, I got to get around to taking some more photos and adding some text to that video.

Those dmm readings were initial start up left side, ~ 1hr left side, right side 1hr, right side a bit of adjustment.

Default two leds in parallel

Hi friends,

I'm building an F5 and I'm using parts methacrylate. I'm using the plates cviller 1.1. The PCB has holes to solder LEDs with cable or mounted on the plate.

I can use this pair of holes to mount two LEDs in parallel with its corresponding resistance? Will it affect the sound charge led PSU with a more?.

The LEDs are blue.

Thanks for your reply. Excuse my English.

The LED's will have to be matched if they are in parallel, you would be better off with the LED's in series.

I finished with my binding posts, and moved it into the bottom shelf of my rack.

It's huge, I've got about 1" of clearance at the top of the unit. Hopefully it will stay cool enough.

If you have decent room around the sides of the heatsink, that will help.

Be glad that you bought the enormous chassis - the heatsink size will help counteract that poor ventilation you have.

Funny Joke about wheater in Uk>Quote

reminds me of an experience I had last time I visited England...

After two weeks of rain in july I asked a young boy passing by :
- Don't you ever have nice weather here? ...
He said :
- How could I know, I am only 16 ...

Is it funny ?
