I'd like to build a 6m SSB amp that uses about 10-14
watts of drive and delivers at least 100w.

Anyone know of plans online for one?

======================
Suggest you have a look at an article in QST-October 1990 ,pages 18 - 21
Title : " A compact brick for 6 meters"
Author : Pat Bunn , N4LTA

Gain : 10 dB Input : 10 Watts A single RF power transistor is
used : MRF492 ( NPN) (perhaps a bit dated ,but readily replaceable by a
current type.

Power supply for the unit : 13.8 V-DC Unit is shown as sitting in a
diecast enclosure with a large heatsink.

Good Luck

it was used in a construction (QST) 20 years ago, and the writer
mentioned it was somewhat dated then, not to easy to get gain. the
only reason to use it was the price, so I wonder if it is difficult to
find a better device now?

My first 6m amplifier from '85 used BLY94 because it was free, but it
cannot give more than 60-70W

I went this route a few years back, built a push-pull MRF476(?) with
bias for SSB, and after messing around with it for almost a year
rewinding transformers and playing with bias and tank caps trying to get
more than 100 watts or so in RF instead of heat I wish I'd just bought a
Mirage or TE and started my current project sooner, building a 6m/2m amp
with a GS35B,

If you really want to build in addition to articles there's
http://www.communication-concepts.com/
with stuff like

My advice:
I think 100w+/- solid state amps are cheap enough to buy used and not
build. If you want to build don't waste your time below +55 dBm, go for
the legal limit.

had some Thomson-CSF devices capable or 350W, but a friend insisted on
trying 2x PL509, although it hasn't been smoke tested, yet. It should
be capable of 3-400W amateur standard performance with -30dB IMD with
only 600V high voltage, see http://home.online.no/~la8ak/d6.htm

Chris, G3WOS has a very well documented compact design using the Eimac 8877
http://www.gare.co.uk/amplifier/

Plenty of power.

from the hospital, nursery, or morgue;
you can at least get rid of all the leftovers in your refrigerator.

1 - 2 lbs. cubed meat (human flesh, chicken, turkey, beef...)
1 -2 lbs. coarsely chopped vegetables
(carrots, potatoes, turnips, cauliflower, cabbage...)
Bell pepper
onions
garlic
ginger
salt pepper, etc.
Olive oil
butter

Brown the meat and some chopped onions, peppers, and garilic in olive oil,
place in baking dish, layer with vegetables seasoning and butter.
Bake at 325° for 30 - 45 minutes.
Serve with hot dinner rolls, fruit salad and sparkling water.



Bébé Buffet 1

Show off with whole roasted children replete with apples in mouths -
and babies? heads stuffed with wild rice. Or keep it simple with a
hearty main course such as stew, lasagna, or meat loaf.

Some suggestions

Pre-mie pot pies, beef stew, leg of lamb, stuffed chicken, roast pork spiral ham,
Cranberry pineapple salad, sweet potatoes in butter, vegetable platter, tossed salad with tomato and avocado, parsley new potatoes, spinich cucumber salad, fruit salad
Bran muffins, dinner rolls, soft breadsticks, rice pilaf, croissants
Apple cake with rum sauce, frosted banana nut bread sherbet, home made brownies
Iced tea, water, beer, bloody marys, lemonade, coffee

The guests select food, beverages, silverware... everything from the buffet table.
They move to wherever they are comfortable, and sit with whoever they choose.
Provide trays so your guests will not spill everything all over your house from
carrying too much, nor will they have to make 10 trips back and fourth from the
service stations.



Roast Leg of Amputee

By all means, substitute lamb or a good beef roast if the haunch
it is in any way diseased. But sometimes su

GAD the cost of that bottle!
A Svetlana 4CX800 is a LOT cheaper.
Many would recommend the 4Cx400A for the power level he wants
but you can (strangly enough) buy the 4CX800's for about the
same price as the 4CX400As. These tetrodes are usually run
passive grid driven (IE: 50 ohm grid resistor) but they can
also be run cathode driven. NOTE: this does not mean grounded
grid since both grids receive normal dc voltages are are grounded
ONLY for RF (IE: with capacitors).
BTW you can do the same thing with good old 4CX250's and 4X150's
if you can find good ones cheap surplus.
