Hi all,
so my celestion sub has died on me, probably my fault for leaving it on all the time...
On inspection, there are clear 'burn' marks to the circuitry inside which appears to be from r115 and r121 blowing in the power amp stage.
Does anybody know where I can get a service manual for celestion subwoofers?
or alternatively how do i go about finding the correct resistor values? they look to be completely 'popped' so can't tell what they were anymore

short up-date, turns out this is the same as a kef PSW2000, and probably many other kef subs, with the same problems which seem to be pretty common. I've found a service manual online, so will have a closer look at it tomorrow and update - the resistors are both1/8w 100ohm, i'll replace them with 1/4w. from the service manual:

it appears r144 and 143 are also gone 🙁
