Hi all,
I know HK990 is quite rare amp, but still hope someone will be able to help me. The thing is it switches off itself with "amp protection" on the screen. Sometimes it works for 30 mins, but in most cases switches off in 2-3 sesc... I've showed it to the technician, he changed some relays and capacitors but it didn't helped at all.
After short investigation on google I found few more threads with same problem described. However there are no answers on how to fix it...
Any ideas? It's too good to dump it :)
