My palomar 150's relay will key as soon as you turn on the power. Plus, it has 6lq6 tubes in the final?? Aren't they supposed to be 8950's?

    I just restored one that came with 6LQ6 tubes. This Amp is kind of tricky to operate. Place the "Operate/STBY/Receive amp off' switch" in the STBY position. Nothing should happen until the On - Off switch is turned on. If you are using it as a base amp or mobile make sure the green wire is not grounded. I hope this helps.

Nope, 6LQ6's are the tube used in most all Palomar CB linears. Most tube type linears of that class have one 6LQ6 driving two or three 6LQ6's. As far as the T/R relay keying as power is supplied, you have an electrolytic capacitor shorted in the Carrier Operated Relay. My advice: get a pro to fix it, as there is 800 to 900 volts DC at a quarter of an amp on the B+ circuit, which is more than enough to kill you if you make a mistake. Too many Hams and CBer's have died that way, I do not want you to have the same accident. Find a reputable repair guy, then pay the price. It's safer that way. Good Luck,

Had 04 transit connect for 6 weeks. always started fine till week ago when turned cold. glow plug light only shows for about 1 second, replaced glow plugs but still the same. can only start every morning...


Sounds like the timer is bad. Since you have power when warm, the power relay must be giving the timer juice. The way it is suppose to work is you wait until the glow plug light goes out and then try to start. In cold weather it should take longer for the glow plug light to go out.

Need to know how to hook a palomar 450 HD to a connex 3300hp


If its in a car or truck use heavy gauge wire to power it. I use a 3ft jumper between the radio and amp. Should use a grounded antenna system. Not a "MAG MOUNT" type. Those can "feed back" rf to your radio and cause problems. If using in the house, a large power supply will be needed.I own a palomar elite 400 hd.It uses every bit of my 30amp power supply. Your hd amp should like the hp radio.

Hi, I have a 96 dodge neon. Im going to start from the very beginning. For about a week my car was having a hard time getting acceleration, then it slowly started to "putter" and shut off, only...


Hi, your symptoms indicate a bad auto shutdown relay or a bad ground to the relay coil. A way to test my theory is to run a jumper wire from the battery positive terminal to the dark green wire with an orange stripe on the positive coil terminal. If this allows the car to run normally, try swapping the relay and removing the jumper. If that doesn't work, I would check to see if there is a ground signal at the computer, pin 67. This is the pin that is supposed to turn the relay on by sending ground to the relay coil. Do not remove the connector to check for the ground signal--you have to probe the back of the connector at pin 67 with the key turned on--this is a dark blue wire with a yellow stripe. You will need an ohmmeter to check for ground by touching the other probe to chassis ground. The meter should read less than one ohm with the key on. Please let me know if you have questions, and thanks for using FixYa.

D/A Raider Ham Tube Linear Amplifier, tube filaments overheat


This is not a transformer problem, it would blow fuses if transformer shorts out. It is hard to say, what could cause the problem without looking at the unit. But, you mentioned new power cord with grounding. That looks suspicious to me. Tyr to diconect grouding wire, and see if that helps.

Tunring up a cobra 150 gtl/dx


Um... What?? This is hooked to a switch? CB radio by FCC regulations is only supposed to have a max of 4 watts total output. If you can flip it to 7 watts dead key, you are doing really good. It won't do much more then that. It sounds like its set up to run on a linear amplifier, which cannot have more then 3 watts dead key transmitting into it.

Dead key, and modulation are different. You may have a meter that only reads dead key, and won't see the modulation. This radio is probably swinging close to 15-20 watts. you need a meter that can read PEP, Peak envelope power. Cheap meters only read AVG, or average power, witch will only show your dead key.

7 watts dead key is really good for that radio.especially since stock only has 4 watts. you cannot get any higher then that without changing finals.

at 3 watt dead key, or 7 watt dead key, your modulation wattage is still swinging much higher.

Also, you will get more swing with a lower dead key any way, which is better if you want it to be loud.

Leave it alone. its probably set just right.

Palomar 150watt bi-linear amplifier for c.b. radio-won't transmit


3W to 150? Now you got 1 W in and 1W out and a snapped resistor. I would look at the driver and or final, either something heated up bad and cooked the resistor or you might have a break in the pcb.

Good Luck, Tom
