Is the transformer firmly and securely mounted and grounded? Perhaps adding MOV's to the primary. 73, Roger W7TZ CN83ia Grid Busters w7tz.webs.com _______________________________________________ Amps

Bill, Your "logic box" is called a sequencer, Does exactly as you describe. Most commonly used for EME or with transceivers and amplifiers. Readily available from many sources. 73, Roger W7TZ CN83ia

Quoting the FCC doesn't make a bit of difference regarding the OP's original question about his amp. It's completely up to him to make sure he is operating within the standards of his country's polic

If you blew the glitch resistors on both amps, I'd say you either have a supply voltage issue, or are running the amps beyond their capabilities. 25ohm resistors are not going to fix the problem and

I used to have a catalog that described how to slow blowers and it depended on the type of motor. One type you can use a resistor in line, the other type requires the use of an ac capacitor in-line.
