I currently use an Acom 1000 amp on 80 and 6m and a homebrew

The features I really like about solid state amps is their efficiency

All of our products are priced based on the cost of goods and on
recovering our cost of development over time. The KPA500 will be
fairly priced using these same criteria.
The KPA500 includes a built-in linear power supply, with a toroidal
transformer, to ensure no added transmit noise.
I hope you've factored in some profit.

No anger with Elecraft, they are my favorite ham company, and I'm quite
proud of my K3 even if it did take months of research and hair pulling
to figure out how to get a decent output from it on SSB.
I am concerned, based on the KPA500 rumors, that Elecraft may be

I am certainly looking forward to getting the KPA500. For me the size,

Is there any update on the timing for availability?

Hi all,
I have been following the discussion of the KPA500 with interest. While we
will have to wait for full specs when the product is actually shipped, a
question I have had for some time is whether the SGC 500 Power Cube would be
a more comparable amp? SGC makes high quality products, in my

40 meters. I sure hope you include one Wayne! (or make it an option of course)

Jack,
Elecraft pricing has been consistent with what the parts cost AFAIK,
plus something to recover engineering and development costs, plus a bit
for profit - and it takes quality parts to build quality equipment.
Those are the main reasons we cannot know the exact price for the KPA500
Regarding the KPA500 internal power supply - is it actively regulated, or
just rectified and filtered DC?

Thanks for the quick reply.
How do you think this unit would perform if powered from a smallish petrol

generator load varied with cw or ssb operation? The unregulated 60v supply

Hi,

engineering standpoint - nobody wants to to design a high power

That makes perfect sense. As with all vacuum tube amplifiers I'm aware of,
regulated power is not necessary, and would significantly increase the cost,
size, and weight of the power supply.

Andy,
It depends on the definition of quite a bit. The power supply is designed
for a minimum line frequency of 50Hz. Higher line frequency will cause no
harm. Low voltage input of 15% below nominal or so will start to reduce
power output. High voltage input above nominal of about 15% will

An unregulated linear power supply is very efficient and very simple. The
only advantage of a switcher is weight.

I wouldn't say the *only* advantage. What about universal, wide input

are 47-63Hz, 90-264VAC input. The switcher would also be regulated. A

I use an Ameritron ALS-600 along with the MFJ 600 watt autotuner.
Together, this combination just breaks $1500. It works superbly with
