I'll put my amplifier on the bench to have a look at...

Not much to see. Both amplifiers are in wooden crates and almost ready to go. They need a shipping address and edges covered in duct tape to prevent splinters during handling.

1kW Larcan 144MHz amplifier. 25W drive produces 1kW output. $1050US total shipped Canada/USA. I've converted about 40 of these, and unlikely there will be many more. 1kW Larcan 50MHz amplifier. 6.5W drive produces 1kW output. $800US total shipped Canada/USA. Both amplifiers picked up from...

There's a 2M Larcan with power supply and coaxial switches on Swap.QTH.com http://swap.qth.com/view_ad.php?counter=1173865

Your tax dollars at work...

Find yourself a tube tester for starters. There are still lots of parts around if you want to look for them. Tube equipment is often much simpler than solid state.

There are a few PL519 on eBay. A tube swap should go fairly easily.

Anything can be repaired if you can find original or suitable replacement parts. What tubes does the amplifier use?

That's the correct power supply. Keep looking and you will see them for $20 plus shipping. If you plan to set up several modules, look for the full frame that will hold six supplies. You can see it at the bottom of the BFLA rack pictured earlier. There is also a 2kW version of the power...

Icom IC746 driving an IC2AT with AT500 tuner. RG142 cable to the balun and then 14 gauge ladder line to the antenna. The rope is the best approach I've come with so far as well.

I have another 8-module wide frame available Garth. It will fit a 24 inch rack or cut it down to 6-modules for a 19 in ch rack. There is another full power supply frame, about 30 amplifier modules, and a second 19 inch rack too. You too could own your very own BFLA...

Pfft. A properly designed and installed station will not suffer any significant damage. No need to disconnect anything and you could operate right through.

How about even higher power? Each module produces 1kW output. I'm going with at least two on 144MHz. Above that and I have to build a combiner.

I'm planning to install a HF dipole fed with 450 ohm ladder line. At the center point I have a Ladder-Loc center insulator by WA1FFL. It looks very good, but I question how much stress it will handle. The copperweld wire will be held in a Pyrex center insulator and the Ladder-Loc will be a...

The bias current will vary slightly as the supply voltage changes. You will be able to get a more stable bias voltage using the voltage regulator followed by a potentiometer. Bypass capacitors and a medium size electrolytic will help keep it more stable.

Get a Larcan solid state TV amplifier and convert to 2-meters. http://members.rennlist.org/warren/2mLarcan.html

Depends on what you're buying. $20 on a $1000 item is insignificant.

The crossed Yagis make an X-shape in place of the driven element of the quad. The existing quad reflector (and director) can remain in place.

Buy more than one and you can get a better price... I have enough for the BFLA and a few spares.
