Hi David

One issue I am aware of and have experienced on the LA-1K 2018 vintage. The ALC and PTT RCA phono jacks on the rear panel are not mechanically secured, only via solder to the circuit card. The legs of the jacks can break and cause either intermittent operation or no operation if the PTT. Causes - twisting and turning of RCA Plug/cable into the jack; stress on cable resulting in forces applied to the jack. I recommend a quick mechanical check - can you move either by hand. The work around for me was using the PTT signal via the DB-9 port. Took me two days of debugging the station to determine the issue and root cause.

Otherwise my LA-1K has been rock solid, no performance issues. Fans are loud even at idle let alone when actively using the amp - just be aware on the early vintage inits. I just replaced with the Icom IC-PW2 (extremely pleased so far) and passed the LA-1K along to a son for his station.

Good Luck

Dave
