Serial number


 

Hello all,?
Just got a used LA1K yesterday. Anyone got info on serial numbers? Just curious how old it is. S# 30659. Also, I noticed in the book it mentions a switch on the side of the amp for 120/240. Mine seems to be absent of this switch. I have both power cords, I used the 120 cord and the amp came on. Any info on this? Thanks

Hi Billy,

Palstar changed power supplies in late 2021/early 2022.? The older ones do not have the switch.

My LA-1K is about 300 higher than your serial and was purchased new in Jan 2019.

Fred,
?Thanks for the response. I was told the amp was 5-6yrs old, so that sounds about right. Appreciate the info on the voltage switch as well. I will call Palstar and get the exact year.?

So are the older units auto sensing voltage?

Mine is. It came with 220 and 120v cables. If your not sure, I would give them a call first before trying as if the switch on the side isn’t changed and wrong voltage you wont be happy.

Yes the older LA-1K's are auto voltage sensing. I just had this discussion with Mark @ Palstar. My amp was built in 2018. Palstar said they staterd using manual switch PS's about 3-4yrs ago.?
