hello
its junk, was junk when new,
age and todays price of sweep tubes do not make it better

seller stating the amp is rare
you do not want a rare amp
you want a common as dirt amp
that you will have no problems finding parts or new tubes for

35 years ago replacing sweep tubes was cheep
use to be could go down to the drug store
buy new set of sweep tube finals
for a Drake or Swan transceiver with lunch money, not any more

tube sellers like Antique Electronics Supply
do not warranty sweep tubes
will not take back bum sweep tubes
if you do not know what you are doing
you can kill a set of sweep tubes in just a few min.

please note, you do not do not want to waste
your time and money on any amp that uses sweep tubes

also the 1,000 watt pep noted is the old
dc input, not 1,000 watts pep output
be lucky to see 500 watts key down cw
for a min or so, before the the glass over heats
and the plates start to warp

want a nice used amp save your money
look for a Heathkit SB 200 or even better a SB 220

there were also lots of good old amps made by
Drake, Hallicrafters, Gonset, Heathkit, Hammond, Hammarlund,

look for a amp that uses real rf power tubes
572B, 811A, 813, 3-400Z, 3-500Z, 4-400, ect
mid power, servicable used amps out there
built like tanks and just as tough
using real transmitting tubes

love WRL gear, have more than one Globe transmitter
but I would never buy this WRL amp

yours truly
