Doesnt happen very often so those who did it deserve the credit .
The CAV A8M comes into the shop badly burned since the costumer plays in the rough side i think probably too loud with heavy loads while the amplifier has been repaired ( badly also ) previously
Inside the notorious SAP 15-P-N inside a circuit that proper balance is very important to achieve stability .Seems that the amplifier has been repaired in the past more than once , probably by the local distributor , and wears inside all shorts of available versions of SAP 15 ...Obviously this is not the way to achieve stability .
On factory though the quality of make , order , symmetry and arrangement on the boards is exceptional for this type of product .After a quick argument with the local distributor who claimed that he never had a schematic a quick phone to Jenny and Ken proved to be a walk in the park and before i hung up the schematic was in my inbox .
That is a service minded company and in the feature i will never question getting a CAV product Already have a pair of speakers that i am thrilled with .
Well done Ken , Jenny thanks to your service minded policy the A8M is up and running again !
In between enjoy some pictures of the repair ...
Kind regards

Hi any chance of getting the service manual or a part number for the volume control as mine is damaged
Hello and welcome! I am asking for help in repairing or for the CAV A8M diagram. The defect is this - I haven't used the amplifier for 3 years - it was renovated at home, it was in a box in a room without moisture. I wanted to turn it on and it doesn't turn on, I can't hear the relay, the display is dark. Is there any RESET for this device? ?? Best regards, Wiesiek,
