Hello and welcome to the Group. The original AC-1 was designed to match dipoles with a nominal impedance of 75 Ohms. The later units with 900 pF loading...
Nothing is wrong with using that 900 pF for the plate and load caps. Don't forget some of the first gen AC-1's were equipped similarly (at least on the the...
Hi, and tnx sigcom1 and catman351 Well, I did change my mind, guess I will go for one 365pF cap and one 900pF cap as I see in other are using. And forget about...
Mark From the FAQ: 3. Where can I find 900pf variables? The original AC-1 used two 400pf variables. In these early units, loading capacitance required for a...

Hello everybody! I was thinking when you using the transmitter with some receiver on the same antenna you will need some kind of QSK unit, I would like to...
Hello, I was fortunate enough to find an E.F. Johnson TR switch on e-bay and this is perfect for what you need. Plus, it will handle a KW through it. 73, Sam...
All: First off, many thanks to my buddy Scott, WB8RAV, for handing me a pair of 75 vdc Zeners. I hooked the two up in series and applied the "top" to the...
Hello to all: Looking for that elusive AC-1? Let this partial kit satisfy your cravings until the real one comes along. I was at my storage unit two weeks...
Hi All: Well, I'm pretty much complete with my 6AG7/6L6 transmitter made from a Chevrolet small block valve cover. The unit was powdercoated the same color as...
I bought this neat little transmitter kit from the old WW Dist. Co., in Memphis, Tn., in 1970 when I first got my novice ticket. I paid $21.95 for it. The...

Cal, An 807 is a 6L6 with a plate-cap, in a coke-bottle (ST) bulb; albeit with somewhat longer internal leads. Look into the famous "QSL-40" series one tube...
