All - Continuing to troubleshoot the HX-500. Making a bit of progress
and finding lots of out of tolerance resistors.
It seems however that the LV choke (pn 26302) in the rig is running
quite hot -- so much that it's uncomfortable to put your hand on the
frame (I tested it first for voltage there... hi hi).
I'm assuming that kind of heat probably isn't normal -- and possibly
could explain the higher than normal voltage coming out of the LV power
supply section?
Anyways, I'm inclined to replace it with something "new", like a Hammond
157M which has the same inductance and series resistance as the original
choke ( 8 Hy and 250 ohms). The 157 is only rated at 100 mA though.
Might anyone have a suggestion as to a replacement, short of having the
original rewound?
Thanks!
