I tried different coloured leds, the blue gave the warmest mids so I stuck with them

 

anyhow

thanks for looking

Hi Fred, this build looks great!

 

Is this a hybrid amp like the Little Dot I+?

Hi sorry I'm not familiar with the Little Dot, My amp is a very standard Starving Student just using 12AU7

I made two PCB:s from the layout Fred shared. Im now unsure If I made the right choice as I mirrored them for the print / tone transfer. Looks as though they are flipped compared to Freds... 

 

The whole thing is on hold, pending parts. beerchug.gif

Just to make sure, this is based on this diagram with the optional bits in yellow?

One last bit of pestering Fred_fred. Looks to me that the resistors labelled on the board are the same as the schematic. On the other hand, the capacitors weren't. Decided to relabel the layout to what I think is correct. Could you give it a bit of a check to make sure I'm right.

Hopefully should be right, first time I've done anything like this.
