Hello Bassbug and Nomadradio: Very impressive reply there Nomadradio, with hands on photos. Great info to know. Especially with the high cost of a pair or even 4 each, 3-500z Tubes. Yeah I can see 4 each 3-500z Tubes, with a can do heavy duty external power supply. The one I seen had a...

Hello Bassbug: This is a aggressive Mod! The SSB220 was designed for two each 3-500Z Tubes. Ok no biggie. Yeah you need a transformer that will output 2400 Volts AC at around 2 amps or more. About 500 dollars from Peter Dahl Transformers. The shipping will be for a 65 pound transformer...

Hello All: The neat O thing about the DX2500 is that it uses the Soviet 4CX800 Tetrodes, in a grid driven circuit. With a slight modification to the Control Grid Circuit a step up toroid transformer like the one in Pride DX300 can be used to allow a stock low power radio to drive the amp...

Hello Nomad Radio: More great info. Does someone have a few photos of the D&A Warrior, that sounds like a rare one. Is the Warrior in the same size box as the Phantom? I am still looking for a Phantom, Pride 300/1KW or a big box or whatever to gut, to put in a couple of 4CX800 tubes...

Hello Nomad Radio: WOW! Truly a impressive posting! Good going, the close up view of the 8950 showing the Cathode wire burning open sure brings back not so found memeries. The Tuning Capacator info surly comes from years of experence. I thought that one production of GE tubes used...

Hello 351 Bear: Yes for 35 dollars a old Penetrator 500 is a good buy. Even if its in bad shape it can be rebuilt, not all that easy to rebuild the base assembly, but can be done if nedded. Jay in the Mojave http://www.a1antennas.com

Hello Desert Rat: How far apart are the two antenans. The closer they are they the more they will effect each other. One good way to tell this is to take down ground plan antenna and see how the Jo Gun II does, measuring local S-Meter readings and field strength tests. Then put the...

Hello 225 in the Great Lakes: It sounds like the Top Hat Radials are not installed, this will make the antenna work at a higher frequency. Or as Master Chief mentioned the vertical element is too short. The Top Hat wires where made from aluminum rod about .12 inches in dia, and where 10...

Hello Nomadradio: Again thanks for all the great info and advice. With the newer bigger tubes I was planning on new transformers and voltage regulator boards, and Vacuum Variable Tuning Capacitors. Biting the bullet sort of. But keeping the original stock look. If possible. I may need...

Hello Nomadradio: Ok good come back good technical data here. Well the 4CX350A has been doing fine for around 3 years now on AM and SSB, in a Pride DX300. If I remember correctly I had to increase the bias voltage, maybe that is what has saved it. But it seems to be working well and...

Hello Master Chief: I would think that the 4CX400 would work, but I would have to look at the tube pin out and chimney. And make sure the screen and control grid voltage are close. I know we have used a 4CX350A and it worked great. I ran accross a Pride DX 300 with a flatter than flat...

Hello Fred: I believe the Chimney was modified or added for the 8930 tube. Jay

Hello Moleculo: Steve has the same problem with his Pride DX 300. He got a better fan and will be mounting it on the back of the chassie. This blower is larger than the stock blower, so more air will flow. Eimac says in the "Care and Feeding of Power Grid Tubes"...

Hello Cheech: Thats funney! We had a forest fire, a few years ago, on the hills near us here in the Mojave Desert. The visting fire fighters from Northern California came up on the locally used Murs frequency. We all took a "stand by" as they surly had emergency traffic that had...

Hello Bob85: I was stationed in your great country for a year back in the early 90's. I thought we had some bad news wind in the Mojave Desert of Southern California. Well we could take lessons from you guys in the UK, having some bad news wind and weather. We had a commercial set of...

Hello All: I wish i had a Dime for every time a ground plane antenna has replaced a none ground plane antenna, and a significant decrease in interference to neighbors electronics has resulted. Jay in the Mojave http://www.a1antennas.com

Hello NS: Ok do these HT's have 4 watts on the lic frequencies or all the GMRS frequencies???? Jay in the Mojave

Hello North Star: We had some locals on murs but they went away??!??!! I do hear a once and a while trucker or two, and some of the guys in the Los Angles area talking, but there are weak. There is a local apartment complex that talks all day about building maintenance, but thats pretty...

I certainly hope the 5 watt input rule is NOT violated here. Way too many knobs and controls for a legal station. Jay in the Mojave PS: The antennas sound like there way too high also!

Hello Pointer: I have to agree with Junk Yard Technology here. I have modified the Little Wil Antennas putting on the good Teflon Coax. Yeah sure like putting ear rings on a pig but a friend wanted it so I did the coax mod to the antenna. In dong so the mod, there is a coil and a...
