I Received what was supposed to be a 300a Palomar.
After I opened the box I reolized that the upper cover was Black. Has anyone ever seen a 300a that did not have the chrome top cover? |

I max about 300 on High. Seems a 300a that I remember should do about 500/550. Just think this might be a differant amp than what it should be.

The one i had did about 550 to 600 on high and it was the "chromie domey"! On low it did about 100 watts so i seldom ran it on low didnt benefit anything by that setting. Hey, did you know the 300a on low will take a 100 watt radio like a RCI 2990? The 300 A is a great older amp but the tubes are hard to find and if you do find them they are really $$$!!!!!!!!!!!!!! |

You benifited as much from that 100 watts than you did from the 600. 100 watts makes a huge difference in your signal. The first 100 watts is the most important

I know that their are differant tubes that I can sub with the originals to get more horsepower, but which ones would be the best to use without over driving it or harming the amplifier? And could having one weak final knock my output down to 300? Thats 300 pep, Seems a little low. |

I have a Skipper with two brand new sets of 8950's for it. Trouble is, my output with this particular amp is very low. It does 150 dead key on high and swings about 230 PEP on sideband. Every other Skipper I've had does 450 PEP on sideband, and deadkeys abut 275 on AM with 2 and 1/2 watts in.
What are some of the possible causes of low output other than tubes? Both sets of tubes test at 100%, and produce 450 in my other Skipper.
Thanks..

Legend.
Is the amp you have the skipper 300 or the 300A?
My 300 does exactly 400 watts from a 100 watt carrier.. I guess this is what its supposed to do..

Cm3885...
I'm not aware of a "Skipper 300A"... Only the 3300, without the "A".
Now... there is a Palomar 300A, but that is not a Skipper. You CANNOT feed 100 watts into a Skipper, unless you like the smell of smoke, but you can into a 300A, as long as it's on the low side.
Does anybody have an answer to my question??
What are the possible causes of very low output, ther than flat tubes? I have two brand new sets of tubes for this amp, that BOTH put ut 470 watts in my other Skipper, but BOTH sets only produce 230 PEP in THIS Skipper. Only 150 dead key on AM. No swing at all on the low side.
Surely, one of the techs here can tell me what might be some of the causes for low output on this amp.
Please? |

Uh i meant the palomar skipper -OR- the palomar 300A... I guess i should have been more careful in my typing so as not to confuse you. I wasnt paying attention to what i typed i guess. Oh well im only human and make mistakes just like everyone else..
I had a palomar 300A once and it worked as you say on the low side and drove it with 100 watts from a RCI 2990 and i got 850 watts swing from the 6LF6s.. No i wouldnt drive a palomar skipper 300 with that much!! |

Trying tighthing the metal clips in your tube socketts.. bend them until you tighten them up.. on the tube pins.. second you could have some weak compacsitors.. feel the compasitor, under a load, see which one is hot. becareful dont get shocked |

Capacitors don't get weak, but they do get leaky. If you have one getting hot, it's leaking bad. You should also note a HUM in you transmit with the amp on. |
