- In a simple 240V circuit (like you would wire for an amplifier), a neutral is not needed but a ground is. Current flows from one hot to another so you would have 2 hots and a ground but no neutral. I

- Bill, I own a used AL-80A and I haven't had it long but it had the same problem when I got it. When I unkey, the receive would be down quite a bit, which means the relay contacts are dirty. I tried a

- Bill, I just replaced my relay and discovered something interesting that you should check. On the pivot side of the relay, there is a screw. If you loosen the screw, you can adjust the angle of the m

- I have an Ameritron AL-82. The SSB/CW switch stopped working. It seems to have no effect. Looking at the schematic, it appears that the switch just shorts a 7.5V zener diode so I am guessing the diod

- I have an Al-82 amp that is blowing the zener diodes in the bias circuit. The first time it happened, ZD1 blew first then a few weeks later, ZD2 blew. I replaced both at the same time and asked the g
