I'm in the process of adding a amp to my atv repeater down here in =
galveston. I have a old Mirage D-3010 uhf amp. I saw in the manual where =
it says  ATV MOD..................................... Remove .1 mfd cap =
and 10 ohm resistor which crosses over both final power transistors and =
connects each base to its collect lead. These cap/resistor networks are =
designed to eliminate low frequency oscillations and will distort ATV =
signals. I've looked and looked and cannot see any cap / resistor that =
crosses over the transistors. Has anyone else does this mod ??

Also I dunno if this is normal or not but when I unkey my transmitter I =
noticed that the power supply that is hooked to the amp surges for about =
a half a secound, it surges up about 5 amps over what it was drawing =
during transmit, any ideas on that one ??
