[ICOM] Problem with IC-781 and rising power

[GGLL]

	Hello, I'm trying to fix a nice 781 with a strange problem. In any 
mode, at any band, after I push PTT for transmit it tooks three to four 
seconds to reach full power (150 watts and whatever power output I set 
with R49). Just the 781 alone, no linear amplifier.
	I've traced that at soon I press PTT, the bias for the RF TX amplifiers 
(Q32 and Q39) raise from -1.6V upto 3.5V in the above stated time 
instead of being instantaneous at 3.5V. Q30 seems to switch properly also.
	I've replaced Q35 which had a small leak, and the ALC system has 
already K1VF ALC mods for the power spike.

Any hint, advice, is indeed welcome.
