Avanti AV-800
It says that the 3 db cutoff frequency is 43 MHz, and that it is
especially useful for Channel 2 and 5 interference. It also says
it is rated at 1000 Watts, but it looks more like 500 to 600 Watts
realistically. $18

$15

Gold Line
Not much info other than it says for use from 0 to 30 MHz, and it
is rated at 1000 Watts. Again, I would say 500 to 600 watts. $17

 AMPHF - FOR SALE - Ameritron AL-1200  
FOR SALE - Ameritron AL-1200 S/N 12607
Clean & reliable. Instant on for bagging that rare one! Genuine Peter Dahl transformer. The power supply has been modified by adding 2 additional capacitors (a total of 10), see the web link in this ad for that write up in my blog.
The Ameritron AL-1200 has a 3,600v power supply. Its filter capacitor bank of eight, 270mF 450vDC runs right at the limit of its design (8 x 450 = 3600). A common modification is to add two additional capacitors, along with the needed bleeder resistors, to increase the filter bank capacity to 4,500v.
Keep in mind that the transformer still puts out 3,600v, so this modification essentially allows the components in the filter bank to have some overhead capacity. $2,000 plus shipping / delivery as required and negotiated with me.
