Firebird Amp, pt2

 I'm using this time to upload some pics, while on the road. I made a bit of headway in repurposing and refinishing the cabinet from the old Firebird amp for the new build. Here's a few pics...

Sanding the inside of the rear panel...

More rear panel work...

The bottom was rough, I sanded the inside...

...and the outside of the bottom panel. Next, sandblasting...

I used the original front panel for a bit of the new front fab...

Below, a piece of aluminum extrusion I used for a new front panel, and attached the upper edge from the old panel.


Test fitting...


After blasting, primer was laid on and sanded...




Front panel in ivory semi-gloss...

Rear panel in Ivory...

The tube socket mount, ready for new sockets.

Bottom side of the lower panel with a wrinkle finish...


A quick mockup...



3 pics above show the top cover in a black hammered finish.

Firebird Amplifier, Gut / Build

 This project started from an old Firebird amp a friend picked up on eBay. It was pretty much junk, but the cabinet had promise. I decided to build a grid driven one or two tube amp in a modified version of the old Firebird cabinet. This would allow operation with low powered SDR and QRP rigs with a power range of 1-5 watts. Stay tuned :-)


Boy, it doesn't look like much, yet. Humble beginnings :-)


I'll cut a piece from this aluminum bar to build a new faceplate.



I'll trim a piece of this to attach t the inner top, and provide an attachment point for the lid.


A piece of 3/8" aluminum u-channel here,xto raise the face plate.




The old rectifier board... I may use this, haven't decided, yet...
