Amp Build: Brown Note 18Watt Lite IIB

The Budda knobs look cooler, IMHO, but they don't turn as easily as the chicken head knobs.

Chicken head knobs it is. :

I agree the Budda's look cooler, but they might be more difficult to turn.

Then again, it's not like you have to turn them in the middle of a song.

Late to the party, but I like either the chickenheads or the triangles. Save the Rat Shack knobs for a pedal!

I like the way you detailed the parts layout on the board, tung. It's really helpful to see just how the board is populated before any soldering begins.

Great tutorial, keep it coming...!

One thing about the layout, it doesn't match Brown Note's exactly. I've taken the liberty of adding another power supply node. The Brown Note schematic/layout have the preamp tube and phase inverter both connected to the same node on the power supply. In that circuit the anode and screen each have their own node on the power supply. I decided to decouple the phase inverter from the preamp. No reason, really. Just wanted to do it. I can reconfigure the circuit and make it exactly like the layout/schematic if I want to.

I got confirmation from both Mouser and Hoffman amps that the parts have shipped. Once I get the parts in hand, I'm going to have the face plate made. I'm also going to have BNP Lasers make me a template so I can route out the hole for the IEC inlet. It will be a square of plastic with a laser cut hole in it to the dimensions of the IEC connector.

Next step: getting the chassis ready for the face plates.

I received all the parts I needed to finish the project yesterday. The next step is to generate the face plate and back plate files. With the 13" long by 2" wide chassis, it is possible to print out 1:1 face plates to make sure the controls are in the right place and are labeled correctly.

After some minor editing, I believe the face & back plates are ready to send off to BNP Lasers. I'm going to go with black plastic with white writing for a Hiwatt vibe. I won't drill any holes for the controls until both plates arrive at my house.

Stay tuned...

Thanks, Shiner. It'll look pretty good once I get it all done, unless I do something stupid to screw it up. Wouldn't be the first time :
