Ice 'n' Lemon 30 Watt Guitar Amplifier
This project contains:
- Four documents (PDF)
- Photos of my constructions
- A full set of mechanical drawings for the enclosure design (PDF)
- A full set of schematics and PCB layouts for the electrical systems (PDF)
- A set of Thiele Small model curves for the LF acoustic response (PDF)
The drawings are in PDF 'A0' size so that no resolution is lost.
Acrobat Reader or similar will be able to scale the drawings according to your printer size. Some colour renderings are also included.
The schematics and PCB layouts are in PDF format.
The photos may be useful as a guide to constructional techniques.
I have obtained from Celestion the T/S parameters of the G12H-30 (8 ohm) that was used in this project.
