Hi Jurgen
thanks for the info. i will try to save the relay, trouble being the thin gauge coil wire has broke where it leaves the coil with not much room to solder an attachment wire but i will have a go, another question do you have any details on the diode (rectifier in manual) it is connected to one of the n/o contacts on the
mute relay as far as i can make out the part is k-f-1203, e45-

Hi
i have swapped valves as suggested but no change, it looks as if i will have to remove the amp, what i have done for the moment until i remove the amp is to switch to " mono" where both of the door speakers operate ok but the sound is not as good

Hi Jurgen
hope you have a good holiday, when i fist turn the JB on to play a record the left channel does not work
that is when i use the AVC to get both channels ,it does not matter the position of the switch by just swiching position brings on both sides, sometimes the left channel fails while a record is playing, i will do as you say by swapping the tubs (left to right) and see what happens
