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...
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...
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...
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...
Hi ! Thank U for ur recent purchase on the Maco 750 kit. It will be in the mail manana.
Finally found 1 of the 3 Maco 200.
Whoo. The last time used one was over 39 years ago LOL ! Did not find my first one.
It's
buried deeper in the garage in a box wrapped in plastic. This one. Picked it up...
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 !
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...
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...
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...
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...
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...
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...
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...
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...
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. (...
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...
