Sound City PA50 Plus is a great platform to make a good Guitar Amp head. This one has lovely transformers and was easy to convert to an Orange Rocker 3o Style amp.. but power output closer to 40 Watts. Enjoyablre project making a great sounding amp!
- As she came in…
- Lovely Sound City 50 Plus PA with one none original knob
- On the bench
- Gut shots.. all original supply cpas need replacing..
- Nice Mullards but only a couple working well…
- Output tubes shot…
- original caps
- Recapped and got her working well on the bench..
- Then stripped out the preamps…
- Replaced preamp initially with a Marshall Plexi Style preamo
- Running well and sounding pretty good!
- Reworked the design to make her a Class A Orange Rocker 30 style amp and she sounds great!
- New Faceplate made up
- In the PA shell
- Modified front panel not lookling so much like a PA.. old Sound City Badge from a 120 Watt amp used…
- Decal ideas..
- All finished and sounding good!
