I designed
this amp (back in 2007) for a buddy, who is now SK.
Current owner is in MT. It uses a custom 253 lb Dahl plate
xfmr and 24 x 3900uf lytics. Vac relays used for the input
+ cut off bias. Paralleled Jennings RJ2B's used for the
output. We tested the manually tuned, tuned input with a
800 watt CCS cxr for 10 mins, on each band. Input swr is
dead flat across all bands. Triple wafer model 85 switch
used for the 12 kw PI net. Multronics MI-14 1/2" tubing
coil used for
160-80-60-40-30m. HB 1/2 tubing coil used for
20-17-15-12m. This is a 9 band amp. 1000 pf @ 15 kv
jennings tune cap. 3000 pf @ 5 kv jennings load cap. Bias
is adjustable, on the fly with a 20 position rotary
switch. Dual line section bird, with 25 kw forward slug
and 1 kw reverse slug. Pep board also installed. Kicks
offline if reflected power too high. 10 kw out with 500w
of drive. 12 kw with 600 watts of drive. 7-16 DIN output
connector. I also have a spare, nib blower, on my shelf.
253 lb dal xfmr has pri taps at 198-208-218 vac....and
also 230-240-250 vac. Sec taps at 2300, 2900, 3900, 4600,
5000, 5400 vac. ( single phase 60 hz). 3 x 300 amp
contactors used on the 240 vac input. One per each
leg..and the 3rd one used for the step start. Separate
step start and variac used for the fil xfmr. There is only
5600 hrs on the hour meter. You need 200 amp service...and
also a 100 amp breaker installed in the main 200 amp
panel...and a min of 3 ga copper wire from main panel to
amp.
