My guess is that these are two separate problems. I have a 563 that has
been exhibiting the first problem for several months and I suspect a leaky
electrolytic(s) on the IF/AF board. I notice that the longer the radio has
been off, the longer the time it takes the audio to return which I believe
corresponds to the time it take the capacitor(s) to reform. So far the
delay has not been enough to cause me to dig into the board so I cannot be
positive as to the cause.
The second problem is probably reed relay K1 on the low pass filter board
which follows transmitter keying. If it sticks closed it will probably
kill most of the received signal. I had a 580 with the same problem that I
fixed by replacing the reed relay. It should be available from Ten-Tec and
not too expensive either.

Radio is "new" to me and so far a nice performer
Two glitches I observe:
(1) Sometimes, more often than not, when I turn on power the S meter is
active indicating signals but the audio is mute for some delay, varies
from
fraction of second to seconds
(2) During a recent ssb QSO the receive would not always come back to
level
it was before transmitting. Keying the PTT will bring it back.
Any suggestions or "yeah it does that" always appreciated
