Hello,
I just bought a HP8561B on ebay but it has a few faults.
1. The unit powers up and basically operates ok. But after a while, it
turns off, turns back on, goes through the start sequence, and then stays on
for a few minutes and turns off again. It cycles through this.
2. Sometimes at some settings it does stay on for a while (20 mins) other
times it justs keeps re-booting.
3. The frequency response also falls off below 1 MHz, to -40 down at 1 kHz.
I assume this is the first mixer.
Any one have any ideas before I waste $600 in shipping costs and send it
back to the US (I'm in the UK).
Regards
Martyn
