    D@A Warrior resurection and bigger Gas tank

    This disabled Warrior was given to me. However. My feeling. The condition it was in. Not worth much. A Lot of work to restore this. Even going with 4x22JG6 and 24LQ6. Its going to cost to put this Godzilla of sweep tube Amps back on the air. My first impression. It is most definitely under...

    Hopefully she will be up & running tomorrow. Not completely finished. But got to fill up the space in my passenger seat ! It has an illuminated on off pushbutton switch. Till my order comes in. Bright Green indicators! Not red. New miliamp meters that will be illuminated by Green Leds...

    D&A Phantom 12 tube promotion to Warrior high drive 2017

    The extra tranny came out of the warrior PSU. It is exactly the same as in this 12 tuber. Forgot the technical name. All the trannys have to be in "phase". These I believe Triad trannys. They could be Stancors. The Allied catalogs listed several manufacturers. They could be Hammils? The way...

    D&A Phantom 12 tube promotion to Warrior high drive 2017

    Re-positioning the trannys. Mounting the 4th tranny. Took a lot longer than I expected. All the hardware was coated with an epoxy resin. Guess they did not have lock washers? Several had to be drilled out. No unsoldering. Just carefully repositioning the wires. Luckily the tranny harnesses...

    D&A Phantom 12 tube promotion to Warrior high drive 2017

    To sum it up. the Warrior is way under powered. All 11 meter sweep tube amps I have run into are. Some worse than others. The goal of this conversion. Is to have a GG linear Sweep tube Amp that does not back swing on vowels. 12 soldiers 4 gas tanks. Option to use a sweep tube driver after...

    Apollo 500 amplifier

    Shoosh instead of editing. How R U loading & tuning the Amp ? R U using a watt meter on the RMS position ? If so. What is the RMS watts ? Properly loading tuning an Amp is by RMS. Not PEP. Tubes or other components in the Amp will be damaged if you are adjusting based on PEP !

    Apollo 500 amplifier

    1000w AM PEP If I understand it correctly. Is 4 x 250W RMS. A Palomar Skipper 300. With 1x 3 x short 6LF6/8950. 3.5 watts to 4 in. Dead keys 300w RMS. AM PEP is 1200w. Most likely. The original band this Amp was configured for. Is not 11 meters. The Skipper if I remember. Is about 800v DC...

    Apollo 500 amplifier

    Cool 2x driving 4. GG AB1. Plate voltage. Most likely is around 700v. Only 2 HV caps in series. Grid tune. Similar to early grey D&A amps."SWR" input impedance matching device. In this configuration. Provided it is driven with 3.5W to 4. Those 6LF6's will last awhile. Separate filament...

    Noob to tubes- Maco 200

    Hmm okay. First thing that is apparent from the photo of the tops of the tubes. Each vacuum tube must have its own parasitic suppressor. That is the resistor connected to the anode/plate of the tube. Not enough photos of the bottom. But. If I remember correctly. The plate choke of the...

    Noob to tubes- Maco 200

    Well. Opinions R like A-holes. Everyone has one. I'm 60+. Been Golden ScrewDriving sweep tube amps since I was a teenager. In my opinion. & from first hand experience. "Balancing resistors" Bleeder resistors R unnecessary in Sweep tube amps with less than 1100v DC at the anode plate of the...

    CALCULATE AVERAGE POWER TO PEAK POWER

    According to Bill Orr I think. Guru of home brew DIY amateur amps. A "GG" grounded grid amplifier carrier cannot be fully modulated to 100%. Unfortunately. No mention. What approximate percentage they can be modulated to ? The Phantom 12 tube in my car. Dead keys 650 watts RMS into a 3/4 Wave...

    Noob to tubes- Maco 200

    Oh' boy. Still happens to me. It is dangerous. If U have to. Make a sign clearly visible on your work space. DISCHARGE HIGH VOLTAGE CAPS BEFORE Touching anything. Hmm Bet that's one of the kits I sell on Ebay ! Insulated handle screw driver. Touch the caps & ground the other end to the...

    Rust removal and painting transformers

    Hold on......Ponder first what a concentrated form of phosphoric acid can do to the Iron. The transformer. Remember. Inside are copper wires wound around the core. These thin wires have a very thin layer of insulation. Check these pics. Before & after. With Prep and Etch sold at HD. RUST...

    Noob to tubes- Maco 200

    Ah yeah. I have two of them. OD Green. Ready for COMBAT ! They will fit M-2057 ! But....really not enough iron. I hate that puny air variable on the bottom ! Years ago was going to drill a hole & mount Palomar Skipper 300 style air variable on the back somewhere. I think it might be a 304.on...

    Noob to tubes- Maco 200

    8950's cost is steep. 6KD6 or 6LB6 best.The Maco 200 does not really have enough iron for 8950,6lx6 or 6LF6. But......Replace the "Parasitic Suppressors" connected to the Anode of tube. US made carbon resistors radically change value with age in that spot. Check the RF choke on the Input. (...

    D&A Phantom 500 resurrection & Re-Tube Need Help hit a Big BumP

    Ahh so hard to find anything on the Allied electronics Web site. they have a 4.5 amp. transformer 20v. Perfect. 6.5 Amp might have a voltage higher than 24v with these tubes. The 24LQ6 Phantom 500 required replacement of the DC blocking cap on the final tank circuit. They would open after...
