I have s/w like that and acts like that on my Astron 35m. It has done that for 30 years plus. PS still works fine. Just like your amp does.

Hello Everyone,
Quick update:? Mr. Mark Ward of Palstar has informed me earlier today, by email, Palstar discovered all of their power switches, obtained from a
new supplier, have the same fault that causes the malfunction as seen here
on my practically new LA-1K (about 4 months old) bought directly from Palstar.
Mark has stated that they will send me a new power switch, from their original supplier, ASAP.
If y'all have been following my postings here, this next new power switch will be the
2nd replacement power switch for my practically new LA-1K.
73,
Ray
