Yes, I understand. The unused metal on this wafer can be an issue. I'll keep looking for a better switch with unneeded metal to add the extra input. Stuff like this is getting scarce. Took me a long time to find a progressively shorting wafer.

I'm replacing the Bypass/Tuner Input switch on my Dentron GLT-1000c ATU to add another input. The new switch is a CRL 2500 series. It is no smaller than the original switch. Can I reliably put a kw through a 2500 switch deck in an ATU for HF? I've owned a few Dentron ATU's that have these...

Looks great, my first CB was an SBE Sierra w/ same knobs layout design, memories.

SSB HT?

A full size, walk-in amp.

Preparing to install new pair of 4cx300y tubes (rated 400w, packed in cans, 1 army green/ 1 silver color). This will be my second tube swap with tetrode amp. When I first got it working I used an old pair of 300Y's to get it going before I installed new 300A's. Past month or so I've got the old...

This is Homebrew category, at best. For the last several months I’ve been watching Marty None videos on YT. They are very entertaining but I’m gob-smacked by the variety of amps he gets to work on. Florida must be far different from up North. His latest video is a Henry 5k. Yes I subscribe...

Summer Heat slowed me down this year. I had to abandon 80 meter plans because I can't make it work antenna wise. My OCF is maxed-out at 95' total. Recall I'm a city ham. I avoid ant traps. Made many improvements on amp though. Transformer for low V power upgraded from 1/2A to 1A and...

I just got a NOS Artesyn LCM600Q, 24-28v, 27 Amps. 100-240v Input Auto Switching. Eventually want another to connect in P. Small size is nearly stunning.

I found the diagram for ACOM 1011 (grid driven 2x 4cx250). It works on 1.8 to 30MHz. The diagrams pi network is legible and shows 790-920pF on Load for 80m for my 2 tubes. My Tune values need another 100pF for 80. I'd never seen a Pride amp in-person or used on 80m but the max Load C of...

The Slinky demo reminds me of Physics class where Slinky's were used to show that different waves pass through each other. Those guys had fun making that video. How did they print that king-size Smith chart laid-out on the Gymnasium floor? The analogy btwn email Spam and Standing Waves...

Got it. My Tetrode project has drained the Brain Trust here over the past few years so, I'm fortunate my membership has not been terminated, lol. Thanks again for filling-in some of the blanks on the formula and process itself. I will report back but it will take some time. My Tune cap only...

Yes, I saw it very early morning while perusing iPhone so I was keyboard handicapped. Always wanted one of those inductors but it's so large.

Interesting new video demonstration posted today on YouTube. Old test equipment something to marvel at.

Thank you Brandon. I’m going to make another try this afternoon if possible. The online calculators wanted values I did not understand and was unable to provide. Your walk thru showed me how to use and apply that formula. I’ll report end values but it will take time, it is ungodly hot...
