I'm in the process of restoring a late model kws-1 which has the test
key that sat idle for many years. I got everything working with fresh
alignment on all bands except for the following: If I key the ptt on the
mic, the amp goes into transmit ok with 100ma of idling current except I do
NOT have any transmit audio but if I activate the "test key" then there is
transmit audio. So before I pull all my hair out can someone please guide me
in the right direction. I've already replaced V103 12AT7 and made sure that
K101 ptt relay works and cleaned all contacts of same without any
improvement.
