I recently purchased a pair of pentas (1's). They were demonstrated as working by the seller, I carefully loaded them and bought them home - a journey of 150 miles.
After setting them up I connected them to a Beogram 9000 - via RCA from pre-amp out as I don't have a Speakerlink cable. One speaker is working perfectly, the other is hissing like a snake. This starts immediately on start up and continues for a number of seconds after switch off. I've switched the wires round = same thing. I have also disconnected altogether and the hiss is exactly the same, suggesting to me that there is a problem is the amp itself.
I don't really want to tackle a complete recap at present as I really want to get these in place and get a feel for the physicality of them. In the longer run I am happy to tackle a more significant rebuild but a repair would be acceptable for now.
I am looking for any suggestions as to where to start. I have downloaded the manual, and would guess the power circuit to be likely. Any pointers gratefully received.
My first post!
