PROTOTYPE AUDIO AMPLIFIER

The revised audio amplifier is shown in a “Flip” video link on the Home page of www.pastimeprojects.com.  It is demonstrating our regenerative receiver. If you have patience, you will see the tuning of am stations, cw and ssb on the 80/75 meter ham bands.  This was taken in the evening with our old 80/40 meter dipole serving as receive antenna  . Demonstrating our 12u7 12k5 ‘space charge’ amplifier with a new front panel, built in speaker, and on-off switch. This amplifier with very slight modifications produced a lot more volume.  We are incorporating this change in the design. We are taking a hard look at costs and hope to add value while containing added costs. More later. Glenn pastimeprojects@yahoo.com
