I have a Cyrus 6 vs2 which has flashing per light indicating an internal problem. I'm new to this unit but have only done minor repairs to audio equipment before and some elections. Would like to sound out the problem to others and hopefully get some advice from wiser heads.

Hi,
In examining the reviews in Hifi News, i can see that many amplifiers use a solder connection of the speaker wire to the amplifier PCB.
I have examined Farnell and RS Electronics, yet i am not able to find such connections.
Does the industry use Turrets to solder to, and a insulating...
I feel I’ve had this amp long enough to do a short review. First of all I have to to give a huge thank you to Colin for being patient with my numerous emails and for being an absolute gent.

Hi everyone,
new to the forum, though I've read a lot. I am looking to buy a pair of Quad ESL 57 speakers, and I hope I can pick your brains about it. Currently there are two local offers I have an eye on. They roughly cost the same. One is a pair completely rebuild by Quad Musikwiedergabe some...

I've picked up one of these old 70's integrated and not even powered it on yet in case there is a staged approach I need to go through first - noteworthy is the old 2-pin UK plug which may mean it's not been switched on for 40 or so odd years!
