8. Run this amp without negative feedback altogether by disconnecting the feedback line from speaker output jack – provides much more overall gain and distortion with the volume up. The Gibson GA5 is a nearly identical circuit to this tweed 5F1 without the feedback. - Page 30 Below are photos and descriptions of the various resistors used in this project.

2. Establish a firm mechanical connection of the components prior to soldering. Solder should only be used to develop an electrical connection and not a mechanical one. TubeDepot.com... - Page 34 5. Feed an adequate amount of solder into the connection for the solder to flow around the components to be joined. 6. When adequate amount has been reached, remove solder and iron simultaneously. 7. Do not move connection or components until solder has solidified. 8. Clip off any excess wire lead(s). TubeDepot.com...
