Just follow the horizontal white line to the end, that is the On/Off rocker switch for the amp only. The red light will come on. The rocker switch on the left is the preamp. The preamp can be used with the amp off as indicated in the instruction sheet. When the preamp is on and the amp is off...

Preamp on left.

Down is AM

Yes, they were nice meters in their day, but whichever meter he decides to purchase, he needs to get it prior to "plug and play" or else he may damage a new amp.

BIRD Model #4410-A Wattmeter and #4410-4 Element

Remember to keep the dead-key at 35 watts and below. Do you have a decent wattmeter to verify the dead-key or are you going to induce the two-watts from the radio and "go for it"?

13.8 might be too much for the 203.

Keep those paper clips away from the top of the power supply. What did you use to attach the + and - wires to the power supply?

Thanks again for the tip. I've been monitoring the power supply volts quite often. 13.8 volts was too much. With 13.0 volts from the power supply and one-watt from the radio, the dead-key out of the 203 is at 25 watts.

55" includes the area in the clamp.

1975! From what I have found, the radials should be 52" long. The radials I have are 55" long. Maybe the original radials were replaced. Would the longer radials have an adverse effect on the performance of the antenna?

Thank you sir! I'm guessing it must be a 70's era antenna. I cannot install / use the three small radials on the top because the 10-32 mild steel screw had broken off.

You will probably need to crimp or solder insulated Ring Terminals or lugs onto the three wires. Are there feet on the bottom of the case to prevent scratching / damaging the desk or table and to allow circulation of air?

Made in USA or CHINA?

After zooming-in on a photo of the power supply, I am assuming the power cord attaches to the N L and Ground terminal screws on the front of the power supply. The instructions probably indicate which color wire attaches to the corresponding terminal screw.

If the power cables are required to be attached to the inside of the cabinet, maybe you should consider having MegaWatt attach / solder the power cables to the inside of the power supply. This will prevent you from tampering with the warranty decal / seal.

I am curious as to where would you install the antennas.

Instructions on how and where to attach / solder the three power leads.

Does the 110V AC cord come with this Power Supply?

Sit back and analyze all your wants, desires, needs and options. You sure as heck don't want to put new tires on bent wheels. Good Luck!
