Gallien-Krueger 800RB Preamp

[disssa]

Here's an example of how some ideas can be implemented more easily by using SMD components.
I built my version of the Gallien-Krueger 800RB preamp some time ago:

However, I wanted to fit the circuit into a smaller 125B package. Despite a very high packing density and the use of smaller component dimensions, I wasn't able to fit everything on one board and in a 125B enclosure. Sometimes, I even considered distributing the components across two PCBs, which would then be "stacked" on top of each other in a smaller enclosure.

Now I've designed an SMD version (and had one PCB populated):

That is fantastic work. Hats off to you for a superb build.

Awesome work!
Are you using traco or recom DC converters?
Mind me asking which series and what filtering you have found necessary.

 

[Aleph Null]

Sexy! What service did you use to get the board populated?

 

[jimilee]

Jesus Christ! Did you build that? Absolutely stellar.

 

[fontoponto]

Crazy!! In a good way!

 

[EisengesisFX]

That's some design AND assembly prowess right there! Long may the clank and punch ring out from this board like its full-size predecessor! (which is also, I gotta add, my favorite ever bass amp)

Man I’d love a real 800rb. How does it sound? Fine work there for sure.

That's one of the, if not THE, best-looking SMD gut-shots I've ever seen. Bravo Disssa, bravo!
