Pick up some old Radio Amateur Handbooks from the 60's and 70's. They have circuits that you can build and it gives info and circuit operation break outs.

I don't see a connection for the B+ to the Tube anodes nor, do I see a tank coil between the Vacuum Variable and the Air Variable on the bottom. PROBLEM: The filament voltage as well as the RF input is situated on the "Top" part of the RF deck along with high voltage and the Kilo-watt...

Not like this where the tubes are wired together in parallel on the same winding: He needs to run separate filament windings for each tube, more like this:

The Carolinas March 21, 22, 23, 2008, both are on the same weekend. Right out side Camp LeJeune in South Carolina.

Who's going where?

That's an interesting amp, however in my experience 3-500Z tubes are not a good choice for a mobile amp. I knew one fellow who ran them and saw 5 grand out of three and he sounded great but, everybody kept cutting his radio off locally and DX. On the shoot-out line, it was like he never even...

Verboden: Haute tension! Have you ever built a tube box (any tube) from scratch? Are you familiar with high impedence devices?

Mission accomplished. Thanks for the input.

The colors and the layout of the WWRF and the ZED are almost mirror images!

I quess the question would better be stated if I said, "has anybody done this mod to their own MKII-G radio and if so point me to the information"?

Has anyone one here had any experience with the modification for full coverage transmitting on the MKII-G?

I intended for the title to say "New" radios. The TS-5010 is AM/FM/SSB and CW Emperor TS-5010 / Alan 9001

I have an Emperor 5010 /Alan 9001 (European version of a Pres. Lincoln), works great and does everything it's supposed to do. So, how does this radio stack up to the newer radios? I like the 5010 because it is easy to work on (no surface mounted parts or micro-fine printed circuit boards)...

I prefer the present color scheme to the other one.

It has to do with the design/function/operation of the AM Detector section of your radio. In "simple terms", after the front-end of the radio, the mixers and etc do their thing, a modulated signal is delivered to the AM detector. Through the "Magic" of electronics (the same principle that...

Shure 444D

Well, well, well I bet that cooled his jets....... Go figure, he brags about ratting his former friends out to the authorities and now he confesses to felonious activities in front of everybody who hates him. Most hams are moral and law abiding citizens, is he really qualifed to hold a...
