Happy Thanksgiving to the whole wireless radio community.
My Palomar 300A would burn the bird...That Palomar has that turkey done, son!!! Bump it down!!
Anyone who's owned, or had the "pleasure" of using the 300a Knows it's probably the hottest running cb amplifier ever made. Unfortunately the one in the photo is toast. I Keyed up after i turning everything one and for some reason the swr light on my Madison lit bright red, and the amps fuse blee. I replaced the fuse, and the amp turned one. I thought I dodged a bullet, but when the amp is keyed there's a lightning show on the underside, and the light bulbs in the shack dim. It's ashame. I enjoyed that 300a for years. Even with the original tubes still in it, and 1 and 1/2 Watt dead key, 12 Watts pep I saw a 500w from that amp. I had Mike refurbish it when I got back on the air about 3 years ago. He did all the upgrades. I don't think it's worth repairing, but I will keep it, and just might send it out one day. My reason for wanting to keep it, and possibly bring it back to life is purely based on sentimental reasons. That amplifier was given to me by a very close friend many years ago (as much of the equipment I own was.) That friend has since passed. And the amplifier is kind of a keepsake that reminded me of him every time I flipped the switch. The thing that pisses me off the most is that I never found out why the SWR was so high upon that initial key down. I learned a valuable lesson. It's something that I never did in the past, but since do every time I decide to fire up the gear. And that is to leave the amplifier in standby until I check the SWR coming from the transceiver. After everything is kosher then I'll take the amps off standby. Had the 300 a been in standby at that moment i probably would still be using it. I switched over to the 350z.That Palomar has that turkey done, son!!! Bump it down!!
May not be all that much wrong with your 300A...Mine last month for no reason at all, popped the fuse and made a loud buzz sound when it blew...Took it to my local tech and found out all it was, was the rectifire diodes decided to let go...He checked all the caps and tubes, replaced the rectifire diodes and $30 later I was good to go!Anyone who's owned, or had the "pleasure" of using the 300a Knows it's probably the hottest running cb amplifier ever made.

The 350Z is nowhere near as good as the 300a was. I get the same output, but the 350Z is very funky when it comes to SWR. I actually read an article on the 350Z, and the SWR issues that can be caused when tuning them up. Nomad actually wrote a few posts, or replies about the highest WR, and why the 350Z causes it while initial tune up is being done. Fortunately I'm not one of those that keep trying to squeeze out, or think that once the amp is in residence it somehow is going to move in some way, and then begin the tuning processes again. It's been tuned up once when the 300a went bye bye, and have left alone. When I first turned up the 350Z I noticed the erratic SWR situations that were being caused while tuning it up. Once it was said and done everything was okay. It's a decent CB amplifier. That's just my opinion of course. In all reality I totally understand that most if not all 11 amplifier are absolutely shit! But I'm a sucker for nostalgia. Happy Thanksgiving 73 s.
I'm in the 90% area in thinking I'll see something as far as discoloration near, or exactly where the light show came from.May not be all that much wrong with your 300A...Mine last month for no reason at all, popped the fuse and made a loud buzz sound when it blew...Took it to my local tech and found out all it was, was the rectifire diodes decided to let go...He checked all the caps and tubes, replaced the rectifire diodes and $30 later I was good to go!
Been working like a champ ever since....Also have a 1x3 Kicker 500 that made a light show from the bottom side once, found out on it, one of the caps was leaking and had to be replaced...That also was no real big expense to get fixed, and it still works as my back-up.
