Preview: Aurora 5120 DIY Preamp & Amp PCB’Coming Soon!

The Aurora 5120 began as a request for a OG Peavey 5150 single channel preamp board. However I knew that a lot of guys on the Metal Musicians forum loved the 5150 so thought I would go there for feedback and input.

This slowly grew into redesigning the board and combining it with my 20w 6V6 push pull power amp to create a low power 5150 amp that doesn’t sound thin and small like the MH models.

In doing this I added the BITE & Feel switches also enabling the user to shape the feel & attack of the Presence and Depth controls from vintage Marshall to ultra-modern. This should lead to a very flexible amp.

I will be testing both boards over the coming weeks and launching them shortly after. The 5120 amp PCB can fit nicely into the smallbox chassis from Modulus Amplification.

Here is a preview of the boards. The preamp uses a mosfet in the output section enabling two output jacks. One coming straight from the tone stack and the other from the mosfet source follower for a buffered output.

The full amp version of the board is also flexible enough to scale the power from 2-100w just by changing a few component values and using different transformers.
