Philco 38-690 electronics restoration.
#63

   

Can't catch a break.
As I also need the tweeters connected I took them off.
The cones aren't good. Though electrically both are ok. One is patched and one is warped - likely water.

Well, after the power-up with no sound......the interstage transformer is also shot. Also the primary. Open.
(More sighs here).

This is in addition to some  sipping under the vanity in the powder room and the Schrader valve from my rear passanger wheel having cone off together with the cap when I tried to check the pressure in it. No inflating that one.

When it rains, it pours, and the frogs get strangled. Icon_smile

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
